Built where email gets filtered
A small, invite-only warmup service for high-volume senders, built from our own sending.
Why we built it
The warmup we could buy warmed filler instead of our copy, and could not tell us where our email landed. So we built our own, and tested it on our own senders first.
Why a sunrise
A sender earns Google's trust the way a day starts: slowly, and in order. The arch is the window you watch it from, and the shape in our name.
What we think matters
- Your copy
- Warm the email you send.
- Nothing hidden
- No code words. No filters.
- Grades, not guesses
- Measured, not estimated.
- Honest numbers
- Every number says where it came from.
What you will not find here
Logos, testimonials or invented counts. Just our own numbers.
Who makes it
Ark Warmup is an Ark OS product. We work by email.
Start your first morning.
