That’s a big mistake for the following reason:

Autoresponders always keep an eye on bulk emailing, especially for newly imported lists.They won’t send the email all at once. Instead, they’ll test it with 50 to 80 contacts first.If the bounce rate is low and there aren’t a lot of complaints, they’ll manage to send the rest shortly after.So what should you do?Divide your imported list into temporary lists of 50 to 80 contacts and send them separately at different times.

Cleaning up your lists must be done for two reasons:

#1: You save money by not paying for large lists, because autoresponders charge based on the number of subscribers.

#2: Your account will be placed in the “good” list by the autoresponder. Keep in mind: accounts with a low open rate, high complaint rate, or high bounce rate will be monitored closely. It will be harder for you to send bulk emails in the future. Plus, your account might be suspended if you receive too many complaints.

Have you unknowingly made any of those mistakes ?
