My Honest Review of Mailwarm

When I decided to test Mailwarm, there were 2 huge dealbreakers:

1. Highly expensive pricing
2. No free trial

If it were not for testing and review purposes, I personally would not have considered paying for Mailwarmat at all!

After purchasing, the setup process was straightforward.

You can connect your accounts via SMTP, tweak the warm-up setting, and start your warm-up.

My email account was warmed up in 2 to 3 weeks’ time.

I ran an inbox placement test with 53 emails sent from professional and personal inboxes:

Overall results

1. Inbox – 55% (29/53 emails)
2. Spam – 21% (11/53 emails)
3. Others – 15% (8/53 emails)
4. Undelivered – 9% (5/53 emails)

Inbox placement by ESP

1. Google Workspace (US) → 80% Inbox and 20% in Spam
2. Gmail → 100% landed in Other
3. Microsoft Business (US) → 65% Inbox and 35% in Spam
4. Outlook → 100% Undelivered
5. Zoho → 100% Other
6. Yahoo → 100% Other

For the price paid, these results do not justify the cost.

In the next section, I break down the pros and cons of Mailwarm to summarize where it performs well and where it falls short.

Pros and Cons of Mailwarm

Pros

• Simple setup

• High spam rate for professional email accounts based on testing results

Does Mailwarm Actually Make Sense for You?

Mailwarm comes with a few fundamental limitations that are hard to ignore.

1. It is expensive
2. Offers no free trial
3. It is not built for scaling across multiple inboxes
4. And shows mixed results depending on the email provider.

When you put all of this together, the value does not line up with the price being charged.

Considering these factors, exploring other alternatives to Mailwarm makes more sense than committing to it in 2026.
