Suppression list
A suppression list in email marketing is a list of contacts who have opted out or should not receive specific communications.
There are many reasons why a specific email address has been added to a suppression list, including:
- Opt-out: Users have unsubscribed or opted out of receiving messages.
- Compliance: Legal regulations (e.g., GDPR, CAN-SPAM) require respecting user preferences.
- Disengaged: They’ve shown consistent inactivity.
- Complaints: Previous issues like spam complaints or hard bounces.
A suppression list helps maintain ethical, legal, and effective communication practices and ultimately improves email deliverability and engagement rates.
