Understand why emails were rejected
See why recipients are landing in your email suppression list. Whether it’s because their email bounced, they unsubscribed, or they reported your domain as spam, you’ll be able to make adjustments.
Ensure international email compliance
Current customers have the right to leave your email list. Comply with email marketing laws like the GDPR and CAN-SPAM Act of 2003 by honoring their opt-out requests and removing them from future emails.
Boost your email deliverability
Improve your sending reputation by removing hard bounces and unsubscribes from your contact list. Export a CSV file of rejected email addresses or delete recipients so they no longer receive email messages.
