How to reactivate a subscriber that reported your mailing list as spam
Some ISPs (Gmail, Hotmail, Yahoo, AOL) allow their users to flag any email as spam. If your subscriber does that to one of your mailing list emails, those ISPs notify us. Then, we remove that person from your list.
Sometimes, the person made a mistake. They ask you to put them back on the list. Their address needs to simply be "renewed" to again receive your list messages.
Step One: Check Audit Trail Report
If your Audit Trail report says Address Unsubscribed - Address On Your Reject List, you must first remove that subscriber from the Reject List. Follow the instructions in Step Two below.

Step Two: Renew Subscriber
Log into your mail-list account at https://database.mail-list.com.
- Click Manage Subscribers.
- Click Special Handling For Subscribers.
- Enter Subscriber email address.
- Choose Renew.
- Choose email to send results.
- Click Special Handling for Subscribers button.

Subscriber will be removed from Reject List and once again added to your mailing list.
