- A campaign is one email, one audience, one departure.
- A sequence is a journey: contacts enter on a trigger and walk it at their own pace.
Before the first email
Four things must be true, and the sending settings screen shows them as a checklist:- your organization is allowed to send;
- a domain is verified and proved;
- the sender address book has an address on it;
- your balance covers the audience.
Who never receives
Three exclusions are applied at departure, not when you pick the audience:- unsubscribed contacts;
- addresses on the suppression list — hard bounces and spam complaints, permanent and organization-wide;
- people who declined the send's topic.
