Why Agencies Are Leaving Shared Warm-Up Pools [2025 Cold Email Guide]

Aug 01, 2025

Shared warm-up pools were once a go-to shortcut for agencies launching or scaling cold email campaigns. By grouping many senders together, these pools promised quicker inbox warming and better deliverability. Over time, though, risks like shared blacklists and inconsistent results started to show. In 2025, this approach is fading fast.

Leading agencies have stopped relying on shared pools and are switching to private, automated infrastructures. Using individual domains and dedicated inboxes now helps teams keep sender reputation intact, avoid blacklists, and gain more control over inbox placement. This shift makes cold outreach safer and boosts positive reply rates.

If you’re looking to grow your agency’s cold email results, it’s time to rethink old warm-up habits. Adopting better infrastructure, automated setup, and closely monitoring deliverability will set your campaigns up for success. The right tools can make this transition easy and help you scale outreach without extra headaches.

The Shared Warm-Up Pool Model Explained

If you’ve managed cold email outreach over the past few years, you’ve probably come across the shared warm-up pool model. This method groups together multiple users or agencies, letting them “warm” inboxes collectively using the same pool of sending addresses. For a while, this was considered a clever shortcut for agencies eager to sidestep slow manual warming and get new domains up and running fast.

But how does this shared model really work and why has it fallen out of favor with high-performing agencies? Let’s break it down.

What Is a Shared Warm-Up Pool?

A shared warm-up pool is a network where several email accounts—often from different companies or teams—send routine, low-risk messages to each other. The goal is to mimic real human activity and convince inbox providers like Gmail and Outlook that these accounts are trustworthy and safe for outbound campaigns.

This approach became common because:

• Agencies could onboard new clients or scale operations quickly.
• Warm-up activity was automated and required little oversight.
• New inboxes “benefited” from established sender reputations of others in the pool.

However, this convenience came at a cost.

How Shared Pools Actually Operate

In practice, a warm-up pool will have dozens or even hundreds of unrelated users’ inboxes added to a central system. Automated scripts send, reply, and flag emails as important, simulating natural conversation. It sounds like a win, but the model has clear flaws:

• Shared risk: If one sender in the pool gets flagged or blacklisted, the hit often spreads to others.
• Unreliable reputation: Bad actors or poorly managed inboxes drag down the trust score for every connected account.
• Lack of control: You rarely know who else is in your pool or what they’re sending.

Inbox providers can spot these artificial patterns and may treat all pool members more harshly over time, leading to less reliable results for everyone.

Core Problems With Shared Warm-Up Pools

The biggest red flag for agencies now is the lack of control over deliverability. Here are some core issues to watch out for:

• Cross-contamination: A single spammer or careless sender can poison the pool, dragging everyone into spam folders.
• Reputation dilution: Shared pools mean everyone’s sender reputation gets mixed together. No matter how well you follow best practices, your results depend on the lowest common denominator.
• Inconsistent results: One day, deliverability is great; the next, it’s awful—with little way to diagnose or fix problems unique to your agency.

If you’re serious about maximizing deliverability and reply rates, these unpredictable factors are unacceptable. Keeping your outreach healthy means controlling your sender reputation at every stage.

How Individual Warm-Up Differs

Switching to an individual warm-up model gives agencies exactly that control. Each domain, sending address, and customer can have their own monitored and managed warm-up process, isolated from outside risks.

Agencies now use tools like Mailerr to set up custom domains, automated warm-up sequences, and separate workspaces for each client or brand. This eliminates the risk of cross-account contamination and gives teams the power to diagnose and fix issues without waiting on the rest of a pool.

For a clear explanation of how sender reputation impacts your cold email performance, SendGrid’s guide on warming up an IP address is a good technical resource.

By understanding the tradeoffs of the shared warm-up pool model, agencies are better prepared to upgrade their outreach infrastructure for safer, more consistent results. The right platform will set you up with automated reputation monitoring, DNS configuration, and domain management—all in a few clicks. This makes scaling campaigns easier and a lot less risky.

The Hidden Risks of Shared Warm-Up Pools

When it comes to scaling cold email outreach, shared warm-up pools may seem like an easy solution. But beneath their surface, these pools often create more issues than they solve. Agencies that stick with shared pools risk deliverability, data security, and consistent campaign results. Let’s break down the specific pitfalls agencies encounter with this model—so you can spot these red flags before they slow your outreach.

Deliverability Pitfalls

Deliverability is the lifeblood of any cold email operation. In shared pools, your sender reputation mixes with everyone else’s, including the worst actors in the group. If just one participant makes mistakes—like sending spammy content, blasting too many emails at once, or ignoring technical setup—everyone feels the heat. Pool members can end up blacklisted together, even if only one email account triggered the alarm.

This sort of cross-contamination often leads to:

• Increased spam folder placement
• Domain or IP blacklisting that’s tough to reverse
• Unpredictable dips in open rates and responses

As explained in Webbula’s guide on understanding email blacklists, even one bad sender in your pool can damage your outreach for weeks. Agencies are learning the hard way that reputation is too important to leave in the hands of strangers.

Lack of Control

With shared warm-up pools, your choices are limited. You can’t fine-tune critical factors like:

• The pace of warm-up activities
• Custom DNS or domain authentication settings
• Profile preferences or tracking domains

If another sender in the pool warms up too fast or cuts corners with domain setup, everyone suffers. The inability to set your own process leaves you exposed to risks outside your control. Agencies that run multiple client campaigns or complex sequences need independence—otherwise, it’s like driving a car where someone else controls the brakes.

Flexible platforms like Mailerr put control back in your hands, letting you manage individual settings for each client or campaign, automate technical configuration, and avoid the pooled risk trap.

Data Privacy Concerns

Sensitive client and campaign data don’t belong in a communal space. Shared pools mean many unrelated senders are on the same infrastructure, raising the risk that your conversations, contacts, or sender profiles could leak or get exposed during a breach.

Some of the biggest worries include:

• Client information being accessed by other pool users
• Accidental sharing of sensitive reply data
• Third-party software issues leading to compromised inboxes

For agencies handling confidential prospects or regulated industries, these risks are deal-breakers. Modern cold outreach tools like Mailerr separate workspaces and offer full admin access, so only you control who sees what and when.

Performance Issues

Shared warm-up pools can bring chaos to what should be a predictable process. Performance can swing wildly:

• One week you see solid open rates; the next, everything slumps.
• Some days messages hit inboxes, other days it’s all spam.

Why? The pool’s effectiveness depends entirely on the habits and behaviors of every participant. If one or two bad actors spike their send volume or trigger complaints, everyone else suffers from lost deliverability. You could spend hours troubleshooting your campaigns with no way to actually fix it.

Agencies need an outreach platform that guarantees consistent performance, not one that rolls the dice based on other users’ actions. By setting up private domains and using tools with reliable monitoring, you bring stability and growth back to your pipeline.

For more insight into how shared reputation can lead to blacklisting, Warmup Inbox’s article on email blacklists breaks down the mechanics behind why pool-based models leave you exposed.

Shared pools may sound practical, but the risks stack up fast—loss of deliverability, control, privacy, and predictability. If you want outreach campaigns you can bank on, it’s time to think outside the pool.

Shifting Best Practices: Dedicated Infrastructure and Individual Warm-Ups

As agencies reevaluate the old playbook, the shift toward dedicated infrastructure and individual warm-ups stands out as one of the smartest moves for 2025. Relying on your own domains and sender setup puts you back in control—no more gambling your inbox fate on what others do. Let’s break down why a private warm-up strategy delivers real-world benefits for agencies driven to protect their reputation, improve results, and keep client data safe.

Benefits of a Private Warm-Up Approach

Moving to a dedicated setup sets agencies apart. When you control your own infrastructure, you decide how every piece is configured and managed. This shift brings:

• Domain reputation control: Using a dedicated domain for cold outreach shields your main brand and makes troubleshooting easy if issues pop up.
• Admin access and visibility: You see all warm-up metrics, sender behaviors, and can fine-tune settings—something impossible in shared pools.
• Custom authentication: Setting up custom SPF, DKIM, and DMARC ensures each domain is trusted by inbox providers. Information on alignment for better delivery is covered well in this practical guide from Mailreach.
• Easier warm-up management: Agencies can warm up each domain at the right pace, suited to individual sending goals.

If you’ve ever had an outreach campaign go sideways and didn’t know if the problem was your setup or someone else’s mistake, private warm-up is a game changer. You can also run split tests or isolate issues quickly since every client and campaign is run in its own clean environment.

Higher Deliverability, Better Reputation

Consistent, reliable sending patterns build trust with email providers like Gmail and Outlook. With private warm-up, you avoid suspicious activity spikes caused by unrelated senders—which often happens in a shared pool. Over time, this approach lifts deliverability rates because:

• Your email volume looks natural to inbox algorithms.
• Authentication is always aligned, so you’re not flagged as spam.
• Reputation is tracked to your domain and IP, not a pooled average.

When agencies use a separate domain for cold email, they protect their main domain from possible damage and take back the reins on sender reputation. Many experienced teams report higher open and reply rates once they drop the shared pool headaches.

Mailerr’s platform, for example, lets you manage every domain under one dashboard so you can identify small issues before they become big deliverability disasters. This tailored approach leads to more emails in the inbox—and more real responses from prospects.

Enhanced Security and Data Protection

Sensitive information deserves better than a shared pool. When you’re on a dedicated setup, confidential contact lists, reply content, and client campaign data are siloed from other senders. This helps agencies:

• Reduce the likelihood of data leaks caused by software bugs or unauthorized users.
• Show clients you take information security seriously, which is key for regulated industries.
• Control who sees, accesses, or manages crucial inboxes and campaign metrics.

With private infrastructure, it’s simple to set up strict user access and audit trails that stand up to scrutiny. Modern cold outreach tools like Mailerr offer separate workspaces for each client or division, letting agencies demonstrate compliance and set stronger security policies. Having this command proves your professional standards and gives clients peace of mind that their data is not just another file in a crowded room.

The new best practice is clear: when you own the infrastructure, you secure your growth and reputation too.

How Agencies Can Move Away from Shared Pools

Moving away from shared warm-up pools isn’t just a technical upgrade—it’s a strategic shift that places control back in your hands. Agencies looking to protect sender reputation, sharpen security, and gain real insight into deliverability need to transition to a dedicated infrastructure. Here’s how to plan the move, set up your new system, and avoid common missteps.

Key Steps to Take: Auditing, Migration Planning, and Phased Transition

Before making any big change, get a full view of your current setup. Start by listing all domains, inboxes, and warm-up systems in use. Track which clients or campaigns rely on shared pools so nothing slips through the cracks.

A phased transition plan usually works best:

• Audit current infrastructure: Map each client and domain. Check DNS, authentication records, volume patterns, and past deliverability issues.
• Plan migration by client or brand: Group accounts that can move together to reduce downtime. Assign priorities—start with low-risk domains before moving your top performers.
• Test new infrastructure in parallel: Launch dedicated warm-up on new domains while maintaining your old pool for a week or two. Monitor results closely.
• Transfer and monitor: Once the new setup is stable, gradually move sending volumes over to your dedicated environment.
• Use dedicated tools: Platforms like Mailerr make these steps faster by letting you manage new domains, mailboxes, and DNS records in a few clicks.

Once you’ve mapped out your move, it’s time to build a system you trust. Setting up private warm-up systems means more than just buying new domains. Here’s what that process looks like:

• Acquire or buy new domains: Secure reputable domains and set them aside just for cold outreach. Mailerr lets you buy multiple domains in bulk or connect ones you already own—keeping all assets in one place.
• Automate DNS authentication: Proper setup of SPF, DKIM, and DMARC is essential for inbox placement. Mailerr helps by automating this process during domain setup, removing a major technical roadblock.
• Create agency-specific workspaces: Run each client or division from a separate workspace. This not only keeps things organized but also reduces cross-contamination risks.
• Manage multiple mailboxes per domain: With automated mailbox creation, you can generate dozens of unique senders in seconds—ideal for scaling outreach.
• Customize sender profiles: Use consistent names, profile pictures, and signature setups to improve brand trust.
• Add monitoring tools: Track opens, bounces, spam complaints, and blacklist alerts to spot problems early.

By automating as much as possible, you spend less time on setup and more on fine-tuning campaigns. Mailerr supports every step above, from one-click domain purchasing to monitoring sender scores and health.

Avoiding Common Migration Mistakes

Switching to private infrastructure is a big win, but rushing the process often leads to headaches. Here’s what to watch out for:

• Sending too fast, too soon: Ramp up volume gradually. New domains and inboxes need time to build reputation. Experts recommend starting with 10-20 emails per day per inbox, then slowly increasing.
• Ignoring blacklist monitoring: Just because you own the setup doesn’t mean you’re safe. Use built-in monitors to catch blacklistings or spam traps fast—this prevents small issues from snowballing.
• Neglecting DNS and authentication: Skipping DNS checks, or failing to align SPF, DKIM, and DMARC, is a surefire way to hurt deliverability. Always double-check records after migration, especially when buying domains in bulk.
• Not isolating problem senders: If an inbox starts getting flagged, pause it immediately. Private systems let you react fast, protecting your other clients and domains.

Migrating successfully means paying close attention to gradual scaling, technical accuracy, and ongoing monitoring. For a broader perspective on successful migrations, Mirantis offers a guide on best practices for migrating to a private cloud environment, which echoes many of these steps—keep your approach structured, measured, and data-driven.

With preparation and the right tools, agencies can escape the shared pool trap, take charge of reputation management, and set their outreach up for long-term growth.

Case Study: Real Results After Leaving a Shared Pool

When agencies step away from shared warm-up pools and build their own private infrastructure, the change isn’t just technical—it’s a complete shift in results. Instead of crossing their fingers and hoping for good deliverability, teams can see exactly what’s working and fix what’s not. Let’s dive into a real-world case that highlights the powerful gains agencies can achieve once they take ownership of their cold email strategy.

Unpredictable Results and Daily Headaches

Agencies in a shared pool often felt like their campaigns were on a rollercoaster. Some days, inbox placement was strong. Other days, open and reply rates dropped with no clear cause. In one example, a marketing agency managed campaigns for five different SaaS clients. They relied on a popular shared pool solution for inbox warm-up, hoping to shorten the path to live outreach.

But problems stacked up quickly:

• On several accounts, emails went to spam, even after only modest send volumes.
• Sender reputation changed week to week, often due to strangers’ mistakes in the pool.
• Troubleshooting took hours. Each new deliverability dip meant digging through logs, guessing if the problem was the agency’s message or another user’s bad habits.

These swings made campaign outcomes hard to predict and left the team anxious about promising clients consistent results. Over time, it was clear that relying on pooled infrastructure created as many problems as it solved.

The Shift to Private Domains and Automated Setup

The agency decided to move away from the shared pool approach and pilot a private setup for each client. Using a purpose-built tool like Mailerr, they bought bulk domains and set up individual workspaces for every brand. This change required up-front planning, but within a few clicks, the agency could:

• Buy new domains only for cold outreach, protecting their main brands from any sender issues.
• Automate DNS records and authentication (SPF, DKIM, DMARC), eliminating messy manual setup.
• Create separate mailboxes and custom profile details for each campaign and client.

The risks of sending cold emails from a primary domain were no longer a factor, since all outreach now ran on dedicated infrastructure.

Measurable Gains in Deliverability and Performance

Once campaigns ran from private domains, results stabilized fast. Key improvements included:

• Open rates rose by up to 40% compared to the final months on pooled systems.
• Replies and positive engagement doubled for two clients within six weeks.
• No more sudden spikes in spam placement. Reputation scores for each domain were steady and easy to track.

The team could identify and pause any sender with trouble, without risking the reputation of other clients. Each workspace had unique settings, tracked performance, and clear issue resolution.

For agencies considering the move, the difference was clear: using separate domains for outreach protects your main brand, keeps problems isolated, and gives complete visibility across all campaigns.

Operational Wins: Efficiency and Client Trust

Switching to private warm-up didn’t just help with numbers. The agency found new operational strengths:

• Setting up a new client campaign dropped from hours to minutes, thanks to Mailerr’s drag-and-drop domain and mailbox management.
• Team members could work inside dedicated workspaces, which kept sensitive client lists and templates compartmentalized.
• Clients noticed faster sends, more consistent campaign reporting, and fewer technical support issues.

Reliability went up, questions from clients went down, and the agency’s team could finally focus on new outreach rather than daily troubleshooting.

This approach didn’t just help one company—it’s become a blueprint for agencies looking for control, speed, and lasting deliverability. The lesson is simple: leave the pool behind and let purpose-built tech like Mailerr set the stage for growth.

FAQs

Agencies moving away from shared warm-up pools have plenty of questions about what comes next, especially when it comes to deliverability, technical setup, and tracking success across multiple campaigns. Here, you’ll find answers to the most common agency concerns, with practical details to help you run cold email outreach that gets real results.

What is a shared warm-up pool in cold email outreach?

A shared warm-up pool is a group of unrelated email accounts bundled together to simulate sender activity. These pools automate the exchange of simple emails between multiple users to “warm up” new sender addresses and boost trust with inbox providers. The idea was to game the system by making new addresses appear safe and human to companies like Gmail or Outlook.

But when many unrelated users, including some who take shortcuts or ignore best practices, share the same pool, reputation problems spread quickly. If one sender gets listed as spam or a domain is blacklisted, everyone in the group suffers. Agency teams may see fluctuations in deliverability or suddenly hit spam folders—sometimes without clear warning.

Are dedicated warm-ups better for email deliverability?

Yes, dedicated warm-ups are a much safer route for agencies concerned about sender reputation. When you set up private domains and inboxes for each client or brand, the domain’s reputation is only tied to your own sending habits—not someone else’s risky outreach.

A dedicated setup limits cross-contamination, keeps your sender score healthy, and makes it easier to diagnose any deliverability dips. Private warm-ups let you pace activity, run separate tests, and control technical setup without outside interference. This approach almost always leads to higher open rates and more reliable inbox placement because your email volume and behavior look natural and consistent.

How can agencies migrate away from shared pools smoothly?

A smart migration starts with a careful plan. Begin by taking inventory of all your current domains, inboxes, and which accounts use a shared pool. Organize this information, then move clients or brands in phases to reduce disruption. Launch the dedicated warm-up for a small group first, check results, then gradually scale up.

It’s a good idea to run your shared setup and dedicated setup in parallel briefly while you monitor deliverability and troubleshoot any issues. Track opens, replies, and bounce rates closely. Once you confirm the new environment delivers steady results, shift more of your sending volume over. For more practical migration tips, see this short guide on mailbox migration best practices.

What technical steps are needed for private domain setup?

Running your own outreach system takes a few clear steps:

• Buy new domains or connect your own for cold email campaigns, keeping them separate from your main business domain.
• Set up DNS authentication: Automate SPF, DKIM, and DMARC records for every domain to verify your emails and build trust with inbox providers.
• Create workspaces per client or campaign to keep everything organized and track sender reputation.
• Add new mailboxes, assign custom sender details, and monitor setup automatically.
• Check MX records and domain redirects to make sure inbound and outbound messages flow correctly.

Tools like Mailerr make these steps simple, automating record setup and letting you manage dozens of domains and inboxes with just a few clicks.

Are there tools that help manage cold email infrastructure for agencies?

Absolutely. Platforms such as Mailerr are designed for agencies running multiple outreach campaigns at scale. They offer:

• Bulk domain purchasing and instant connection,
• Automated DNS authentication (SPF, DKIM, and DMARC),
• Workspace management for every client or campaign,
• Monitoring tools for blacklist status, bounces, and inbox health.

These platforms save time on technical chores and allow you to focus on writing good emails and closing deals. Instead of wrestling with spreadsheets or different providers, you handle everything under one dashboard.

How can agencies track deliverability when using multiple inboxes?

Staying on top of deliverability across several inboxes requires constant monitoring. Agencies should:

• Use dashboards to watch open rates, bounces, and spam complaints in real time,
• Track sender reputation and domain health for each account,
• Set alerts for sudden dips or blacklisting events.

Dedicated cold email tools show all this data in one place, so you see problems before they grow. Segment reporting by workspace, client, or campaign makes it easy to spot which inboxes need attention. When agencies use their own infrastructure, they can pause problem accounts quickly and keep the rest of their outreach running smoothly.

Is it worth the investment to buy new domains for every client?

Yes, buying unique domains for each client or major campaign is worth the cost for serious agencies. Owning these domains keeps your main brand safe and avoids risky cross-brand contamination. If one campaign runs into trouble (like high spam complaints), the fallout is limited just to that domain, not your entire operation.

With domain prices as low as $14–16 per year through platforms like Mailerr, the return on investment is clear. The cost is small compared to the risk of getting your primary company address blacklisted or harming deliverability for every client at once.

Plus, bulk buying and automated setup mean you don’t waste hours on technical work. It’s a straightforward step for agencies who want reliable campaigns and happy clients. For more on secure migration and setup strategies, resources like migrating from on-prem mailboxes to the cloud provide helpful frameworks—though dedicated cold email tools simplify even further.
