Sending limits and warm-up

Set these in Settings → Sending → Schedule & limits.

• Emails per day, per mailbox: 15 by default, 50 at most. Every email counts, follow-ups too.
• Sending days and hours: Monday to Friday, 9 AM to 4 PM by default, in each company’s own time zone. A company in California gets its email in California business hours.
• Spacing: emails go out a few minutes apart (4 to 11 minutes by default), like a person sending them.
• Follow-ups: 3, 5 and 7 days apart if they don’t reply. A reply stops them.

Warm-up

New mailboxes start at 10 emails a day and add 2 a day until they reach your limit, so email providers learn to trust them. If a mailbox is already in regular use (older than 3 months, sends and receives every week), you can skip the slow start in Settings → Mailboxes.

Safety pauses

If too many emails from one mailbox bounce, that mailbox pauses itself and you get a notice. Check where those addresses came from, then press Resume sending. Your other mailboxes keep sending.
