Warm-up that only writes to our seeds.

Warm-up has a new mailbox send a few ordinary emails a day to SendPath's own seed mailboxes, which open them, rescue them from spam and reply. New mailboxes need about two weeks.

Warm-up

How it works

  1. 1

    Start it when you want

    Warm-up is off until you start it, mailbox by mailbox. It's never switched on for you.

  2. 2

    It ramps up gently

    Day 1 sends 3, then 2 more each day up to 40, and less at weekends, like a real person.

  3. 3

    It stays out of your inbox

    The seeds reply to a private address of your mailbox, and a filter files those replies away as they arrive.

FAQ

Questions, answered

Will warm-up email my contacts or other customers?+

No. Your mailboxes only ever write to SendPath's seed mailboxes.

Can I send campaigns while a mailbox warms up?+

Yes, at low volume. A mailbox that has been sending well elsewhere can skip the slow start, but it still has to prove its inbox placement.

Does it work with a sending service?+

No. A mailbox connected through a sending service like Resend or Amazon SES doesn't warm up.
