There are 5 types of Contact status in CRM. The status will be changed automatically based on the audience’s response, also you can change them manually.

Pending #

Someone who has interacted with your lead source, but hasn’t opted in to receive your email. This is the default status of an audience. All pending audiences will get a double opt-in email to confirm their subscription. This is required by GDPR policy and is very useful to avoid spammer.

Subscribed #

Someone who has opted in from your lead sources and also confirmed the double opt-in email you sent.

Unsubscribed #

Someone who was opted in to receive your email marketing campaign but currently opted out.

Bounced #

An email is marked as bounced if a double opt-in email has not received by the recipient’s mail server and returned to the original sender. A bounced email means that your mail has not been delivered, this happens if the email address is invalid.

Complained #

If a double opt-in email is received by the recipient’s mail server but the email delivery is rejected by the server’s API.
