When do follow-up emails stop, and can I stop them for one person?

Follow-ups stop by themselves when you mark the lead Contacted, Booked, Won or Lost, or when they unsubscribe. Every email has an unsubscribe link and your mailing address, and replies come straight to your own inbox.

A person never gets more than one email a day (the thank-you counts), and an email that can’t go out within a day of its time is skipped, never sent late.

For one person, open them in Leads and use Pause, Resume or Stop under “Follow-up emails for this lead”. For everyone, open Follow-ups and tap Pause or Turn off. Nothing goes out while paused, and emails that fall due meanwhile are skipped.
