Rather run it yourself? Self-hosting is free, forever. Once Warmbly Cloud launches, link your instance and we run the warmup for your mailboxes in the shared pool, free for up to 10 mailboxes and $15 a month for unlimited. Everything else, sending, inbox, campaigns and data, stays on your server.
Free to run. We handle the warmup.
The whole platform is Apache 2.0 and costs nothing to self-host. When Warmbly Cloud launches, link your instance from Settings and the mailboxes you choose warm up in the shared pool, with thousands of real mailboxes sending, replying and rescuing from spam, while campaigns, contacts and inbox never leave your server.
- Unlimited mailboxes, campaigns and contacts on your instance
- Link in about a minute with a one-time code
- Only the mailbox credential travels, encrypted, for warmup
- Unenroll or disconnect any time; the cloud forgets it immediately
