Cold Email Deliverability Infrastructure for Agencies

Key Takeaways

  • Gmail and Outlook break under cold email volume.

  • Aerosend offers multiple inboxes with reliable deliverability.

  • Built-in warm-up, rotation, and alerts keep campaigns safe.

  • A single dashboard removes manual maintenance.

  • Teams focus on leads and deals, not tech.

Cold Email is your bread and butter. We understand that because it’s ours too.

At the end of the day, every booked meeting is additional revenue and directly impacts client retention. You spend money creating campaigns and building lead lists to achieve a consistent flow of replies. That’s what your clients trust you to do. Book meetings/generate positive replies.

However, all this collapses if your emails never reach the prospect’s inbox. The whole premise of what you were good at doesn’t work just because you have poor email deliverability. Deliverability is hard to reverse-engineer, tough to manage, and impossible to control.

This is precisely what we solve here, too. We built private infrastructure so that your cold emails can land in the inbox reliably, consistently, every single time. Built on first principles, Aerosend gets better deliverability rates than Google/Outlook or many others in this space without getting any bans

Why Aerosend

1. Premium Deliverability Set Up – We give you the best of all worlds:

  • Aged and Clean IPs
  • Dedicated Servers
  • Completely Isolated Infrastructure for every 10 domains
  • Premium Warmup from Warmupinbox.com and Warmy.io
  • Dynamic Warmup Settings
  • Self-Optimizing Infrastructure

2. Deliverability Monitoring System and Domain Burn Alerts

You don’t need to manage and track deliverability for each individual inbox anymore. Aerosend constantly monitors deliverability and alerts you if anything goes wrong.

  • Monitoring Warmup Pools: We consistently monitor 6+ warmup pools and evaluate ESP mix, bounce rates, average domain age, and spam trap rate to ensure everything is running smoothly.
  • Domain Burn Alert: We track individual domain performance and send you alerts to slow down/replace domains
  • Dynamic IP Rotation: If an IP burns, we replace your IP dynamically

3. Scale

We allow you to scale without any disruptions. No blocks or additional verification required.

4. No Bans, Blocks or Disconnects

G Suite and Outlook keep disconnecting. Our inboxes ensure you don’t experience any disconnects.

Why Your Current Process Is Not Optimal For Scale

If you’re not able to scale effectively, chances are you are getting inboxes from the following: 1) Creating your inboxes with Google/Outlook: You are paying $8/month for inboxes and constantly get hit with ID/Phone number verifications. To maintain this, you have to run proxies, headless browsers, and virtual cards. It’s an expensive and cumbersome process.

You are using resellers:

  • Your reseller adds you to his 300-domain panels or legacy panels. These domains are “hacky” ways to get inboxes. They share a centralized reputation, have the worst deliverability, and are constantly shut down by Google. As a result, you lose the investment/domains.
  • You use official resellers: Even though they may not face the same issues as unofficial resellers, they still get the worst IPs. They also have a centralized reputation to an extent, and your accounts die every 2–3 months.

You use a “fake” private infrastructure:

Some companies masquerade as private infrastructure but are actually resellers of SMTP infrastructure. They have no control over deliverability.

You are managing deliverability on your own, or not managing it at all

Managing deliverability is a very tough process. You need to cross-check multiple metrics, create individual ranges for different clients, and understand where it is going wrong before it happens. If you are on other platforms, you should be reducing sending from at least 10% of your domains every month. Are you doing that right now? Stop risking your agency. Let us take care of your deliverability problem. Focus on building great campaigns. That’s how you win.
