Burned domains
One bad ramp and the domain you waited weeks to age gets flagged, sometimes for good.

Mailflow warms up your inbox automatically so your emails land in the primary inbox.

Where your cold emails actually go
There's an invisible gatekeeper between you and every prospect: The spam filter.
It decides (silently, before a human reads a word) whether your email exists.
On a fresh domain, it decides against you.
Wasted spend
Every hour on lists, offers and copy is thrown away when the mailbox kills the send.
A pipeline that quietly dries up
Replies fall and you blame the message, when the real problem was placement all along.
Warm up in three moves
You did the work.
Your emails should reach a person, not an algorithm.
Here's how Mailflow gets them there.

We warm it automatically

Land in primary
Watch inbox placement climb on your dashboard while replies start coming back where they belong.
