I have 59,000 customers I want to send email campaigns to. I made several groups of customers so that they would be under the limit of 40,000. The largest being 28,000. I sent an email to each group, but only the one under 3,000 completed successfully, the others sent to about 30% of the group. The only error I got was a message about cleaning my subscriber list. Can any body help?
Hello @jtruffa John,
That's happening because the system recognizes/find some fake customers (may be spam bots registrations) in the list you are sending to. So, you will have to remove the fake customers/emails and then start the campaign again. And that process will be a manual review process where you will review customers one by one and delete the one who are fake.
