Warm up a new email domain before it matters.
New domains and new inboxes land in spam because nobody knows them yet. We build their reputation slowly, the way mail providers expect, and show you where your mail actually lands.

How it works
- You connect the inbox you'll send from
Your mail keeps going out through your own provider, from your own address. We never send your campaigns.
- It sends a few real-looking messages a day
To a group of mailboxes at Google, Microsoft and others, during your working hours, a little more each day.
- The other side opens, replies and rescues
If a message lands in spam, it's moved to the inbox and marked "not spam". That's the signal providers trust most.
- You see where your mail lands
Inbox, spam or promotions, by provider, plus checks on your domain's settings and on spam lists.
What we'll tell you straight
Warm-up helps a good sender get started. It can't fix mail people don't want.
You'll get two numbers, not one. How your mail lands with our warm-up group, and how it lands in a separate test where nobody rescues anything. The second one is the honest one.
We only touch our own messages. In your inbox the service acts only on the warm-up messages it sent. Your other mail is never read, stored or moved.
Who it's for, and who it isn't
- Businesses starting a new domain or adding inboxes for sales, support or newsletters.
- Teams whose mail started landing in spam after a change.
- Agencies setting up sending for clients.
Not for purchased lists or bulk mail to people who didn't ask for it. We check every domain before it joins, and accounts that collect spam complaints are removed. That's what keeps the group healthy for everyone in it.
