Warm-up helps establish consistent sending behavior before you launch campaigns.
Genuine-looking activity, built up gradually.
A new mailbox has no sending history. Warm-up gives it one, steadily, before you ask it to carry real campaigns.
Our warm-up network
Your mailbox communicates with the Infrabox warm-up network, where emails are exchanged automatically.
A gradual ramp
Activity builds over time instead of jumping straight to full volume, which is how reputation is earned.
Consistent sending behavior
Regular, steady activity helps establish the consistent pattern mailbox providers look for.
Bring your own mailboxes
Already have mailboxes? Connect them directly through Infrabox and put them on warm-up too.
From cold mailbox to campaign-ready.
Warm-up sits between mailbox setup and export in the Infrabox workflow.
Step 1: Enroll the mailbox
Turn on warm-up for mailboxes bought through Infrabox or connected from your existing providers.
Step 2: Let the network work
Emails are exchanged automatically with our warm-up network for at least 2-3 weeks. Longer is better for reputation.
Step 3: Export and launch
Once warmed, export the mailboxes to your sequencer and track their performance in Email Insights.
Two to three weeks minimum. Longer if you can.
Reputation is built, not switched on. Infrabox recommends a minimum warm-up period of 2-3 weeks before large-scale campaigns, and longer warm-up periods can be used for better reputation building.
