Add contacts to a sequence

Add contacts to a sequence

Enrolls saved contacts in an Apollo sequence so its email steps go out from the mailbox you choose.

Note: Only saved contacts can be enrolled, so create the person as a contact first, and pass a sending mailbox id from the email accounts list. Enrolling can start real outbound email: confirm the sequence, mailbox and contacts first.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
