Warmup

Every new inbox warms up on its own before it sends at full volume.

How it works

Each inbox exchanges a small, growing number of emails with our warmup network, which opens, replies and moves mail out of spam.

Choose 14, 21 or 30 days in Settings → Sending defaults. Volume ramps steadily to your daily limit.

You can send during warmup, but keep it light until the inbox shows Ready.
