Open Integrations, then Email. Check two things: that your mailbox says Connected, and that you have not used up your daily or hourly limit shown under Inbox ramp.

Check these in order
- Is the mailbox connected? It should show Connected. If not, click Sync, or remove it and add it again.
- Did you hit the limit? New mailboxes send a limited number of emails and build up over 30 days. On day 1 the limit is 10 a day and 5 an hour. Today: 10/10 or This hour: 5/5 means you have used it. Wait for the next hour or day. See How to check your email sending limit and Inbox ramp in FlowForce.
- Check the status of a one-time send. In Sequences, a quick email that did not go out shows Failed. Open it to look at the details. See How to read your sequences and what each status means.
- Check the Sent folder. In Inbox, open Sent to see whether the email left.
A sequence is not sending emails
Check that the sequence status is Active and that the lead is on it. See Why is my FlowForce sequence not sending?.
