Emails which are returned undelivered are called bounces. It can affect your IP and sender reputation immensely, so much that when it reaches a certain amount, your account can be banned!
How does one navigate this tricky issue? Listed below are some key pointers on how to weed out the errors causing bounces.
Do not have invalid email addresses in your lists. They are parasites that infect your email campaigns.
Do not allow any formatting errors in your emails such as invalid email addresses, typos in domain names, and so on.
The @ sign is the symbol of email and believe it or not, it is frequently replaced by the number 2 or just plain missing!
ESPs provide granular delivery reports. Please request for one and make sure you go through it, inside out.
Send welcome emails to all the email addresses to track if they exist. This is by far, the best method of confirmation.
Test the heck out of your list. It doesn't hurt to recheck, you would rather be safe than sorry.
Set a bounce threshold, below the threshold of your ISP. Then you can act before its too late.
Track your delivery reports based on various criteria such as domain names, email addresses, time of sending and so on. If you see a negative pattern, hit the panic button!
Regular updates ensure your list is clean and ready for work.
