6y ago, Mailwarm was #1 on PH. Today, we’re launching Mailwarm 2.0. First again ?
Hey Product Hunt 👋
Almost 6 years ago, @Mailwarm launched here.
Back then, the idea was simple: help teams warm up their inboxes and build sender reputation before scaling email.
That launch changed a lot for us.
Mailwarm became #1 Product of the Day 🏆 and Product Hunt helped us get our first real wave of visibility, users, and feedback.
Since then, we’ve spent years working on email deliverability with founders, sales teams, marketers, agencies, and operators.
And one thing became very clear: Email warmup alone is not enough anymore.
Teams don’t just need emails to be opened and replied to.
They need to know:
where their emails land
what affects their sender reputation
whether their setup is healthy
when something breaks
what to fix before campaigns silently die in spam
That’s why we’re preparing Mailwarm 2.0. The original email warmup tool, upgraded.

A premium email warmup and deliverability system.
With Mailwarm 2.0, we’re bringing together:
automated warmup
50,000+ real inboxes
human-like engagement
inbox placement monitoring
B2B and B2C warmup
infrastructure checks through @mailX by mailwarm
warmup with your own content
deliverability experts available for every subscriber
The mission is still the same as day one: Help your emails land in the inbox, not the spam folder.
To PH community:
If you use email for growth, what’s the hardest part today: warming up, monitoring, understanding issues, or knowing what to fix?

heyyy, congrats on the launch! wishing you the best. btw i'm curious how mailwarm 2.0 handles the diagnosis part: when something does land in spam, does it surface why, or more "here's what to check"?
