Email health check.
But effective.

If you’re still using classic email health checkers, you’re probably running into these two problems:​

  • they only do a one-time check of your deliverability or technical setup (which may or may not detect issues); or

  • they only show you the problem but do not offer an effective solution.


We do it differently. 

Warmup Inbox is not only detecting your deliverability issues in real time, but it is also improving your deliverability.

How does it work?

​The email warmup process is quite simple. 

  1. You sync your email inbox to our platform and we'll send emails on your behalf to other users within our network. Your inbox will be communicating with real users, just like you. The whole process is automated, you don’t have to do anything.

  2. The power of correlation: If your warmup emails are landing in spam, your real emails are most probably also ending up in spam. So by sending the warmup emails, we are able to detect any deliverability issues immediately and more accurately than any other email health checker.

  3. Your Live Performance Tracker will notify you about any deliverability issues so you can immediately pause your active email campaigns. This will save you from ruining your email reputation. (Trust us, it can happen really fast).

  4. Meanwhile, we interact and engage with your warmup emails. We reply to them, we mark them as important, we unmark them as spam, etc… All of this will restore your reputation and train ISPs & Mail Servers to view your emails as valid and safe. This will happen as long as you stay connected to us.

  5. Once your deliverability improves again, you can resume your current email campaigns.

We all know that in cold email marketing, your email health may be OK one day and go down the tubes the next. Because of that, you should always be working to improve your email deliverability.


Simply put, you need real time health monitoring + email warming at the same time, at all times.

Warmup Inbox is the solution.
