Opt-out Number
- Combines unsubscribes + invalid emails
- Broader view of contact list health
BranchUp periodically verifies all emails using a reputation service to minimize bounces. When agents upload a contact list, each email undergoes this verification process. Emails flagged with a poor reputation are automatically marked as 'Opted Out'.
Common Reasons Emails Get Flagged
- Closed email accounts
- Typos in email address
- Non-existent domains
- Full mailboxes
- Expired temporary emails
