Emails are not sending

Check the record first: a message that was held back says "Not sent:" with the reason.

Likely causes, in order

1. Client messaging is still off. Nothing goes to a real client until an admin switches it on under Settings, System, Sending. Only the test contacts and the team get emails until then. See Turn on client messages.
2. No mailbox is connected, or it needs reconnecting. Open Settings, Me, My email. A mailbox marked Needs reconnecting, or showing a red message, cannot send. Press Reconnect. See Connect your email.
3. No address is chosen for automatic emails. Reminders and receipts go from the address under Automatic emails go from on Settings, System, Sending. Pick one.
4. The client said no to emails. "Not sent: ... does not want emails." An unsubscribe switches Can email off on their record. A client set to booking emails only gets nothing else. See Unsubscribe and STOP.
5. Email is off on the task, or the notification is off. Check the stop's Email box, and the moment under Settings, System, All notifications.
6. It went, but to junk. Your domain may be missing its sending records. On your mailbox, check Deliverability: SPF and DKIM should say found. Ask whoever runs your domain to add the records it lists.
7. The team member has no email on their profile. "Not sent: nobody this goes to has an email address on their profile." Add it under Settings, HR, People.

Good to know

• The Outbox on the Inbox lists messages that did not go on their own and why.
• Settings, Tools, Health shows mailboxes that stopped working and messages that failed.
