How many mailboxes can I connect and warm up?

Connected mailbox limits by paid tier:

There is no per-mailbox fee on any paid plan — you can warm up every connected mailbox at no additional cost. On the Pro plan at $14.99/month, you can connect 5, 50, or 500 mailboxes — there is no enforced cap. Email warmup runs on all connected mailboxes simultaneously. Your other constraint is your monthly email quota (e.g., 10,000/month on Pro), which is shared across all mailboxes and all sending activity (warmup + campaigns).
