Remove Inappropriate Emails to Avoid Temporary Blocking

Because of a temporary block at the ISP, good email marketers who perform regular list hygiene may be unable to distribute messages to a certain ISP. Messages in this case typically bounce with the “too many invalid email addresses” error.

A temporary ISP block is not as dangerous as a permanent block because it is usually valid for 24-72 hours, and you do not need to contact the ISP to get it removed.

However, a momentary blockage warrants your attention as well. At best, you won’t be able to send messages to valid addresses or detect which ones are invalid until the block is removed.

If you do not take action, your emails may be vulnerable to more severe filtering or possibly permanent blocking at that ISP.

Are You a Candidate for a Temporary Ban?

If you adhere to email list cleaning and remove problematic email addresses as soon as they bounce, you will most likely avoid a temporary ISP ban.

The following email marketers are at risk of being temporarily blocked because of incorrect email addresses:

  • Marketers who employ bad email acquisition strategies to build their list without much regard for quality.
  • Marketers who send to old lists regularly in an attempt to re-engage inactive
  • Marketers that have just switched email service providers but have not practised effective or consistent list hygiene.

How to Reduce Your Chances of Being Temporarily Blocked Due to Invalid Emails

You may lessen the chance of temporary block for incorrect addresses and enhance email delivery by following these easy but critical tips:

Organize your email gathering procedure. This is where you should begin. Forget about collecting or purchasing email lists. Put a signup form on your website and let individuals sign up on their own. To minimize bad and misspelt emails, you should ideally set up a double opt-in process. To catch and block mistyped email addresses, add an email confirmation field to your form if you employ a single opt-in process.

Check old lists. If you haven’t emailed your list in a year or longer, it’s a good idea to validate old emails before sending a message to them. At the very least, you will identify some of the dead emails on your list.

Remove any emails that have bounced from your list. After the initial bounce, carefully examine your mailbox for returned messages and remove invalid email addresses from your list. Consider creating a separate mailbox for returned messages so that bounces are not mixed in with your regular messages. Then, in your email sender application, enter it as the “Return email address.” Bounces will be collected in a separate mailbox, which you will check regularly, and bad addresses will be removed from your database.

The aforementioned strategies necessitate consistent effort and patience. Depending on the size of your list, setting up the procedure could take several days. However, it all begins with the sign-up process. If you don’t avoid unsafe email collection methods, you’ll merely waste your time and effort trying to email list cleaning.
