Domains, sending limits and warmup
Bring your own domains. Domain registration and renewal are not included. Each managed domain supports up to 5 mailboxes.
Your email service’s limits and sending safety checks also apply. Managed mailboxes ramp gradually, up to 50 automated campaign emails per mailbox per day. You can choose a lower limit.
Warmup is optional, uses a shared network and can be turned off. There is no separate plan limit for warmup, and it doesn’t use your campaign email allowance. Warmup analytics cover the last 7 days; inbox placement is not guaranteed.
