Hi, I have inherited a list of about 28,000 emails.
In my first mailing I received almost 4,000 rebounds.
What protocol should I go for proper cleaning of bounced emails? Can you please explain the steps? (or point me to a thread...)
If you've setup bounce handling properly (Step 7 of Get Started Guide), all 4,000 bounces would be flagged in your list.
You don't have to do anything, future campaigns will not be sent to them. Future imports of the same emails will not be re-imported.
