Sometimes email marketers who maintain good hygiene on their lists aren’t capable of delivering messages to an ISP due to an intermittent blockage at the ISP. In this case, the emails generally bounce due to the “too too many email addresses that are invalid” error https://www.growbots.com/blog/how-to-test-email-deliverability-and-verify-email-addresses/.

A temporary block from an ISP isn’t as big of a issue as a permanent block as it’s usually valid for 24 to 72 hours and you don’t need to call the ISP for elimination.

But the issue of a temporary block should be taken into consideration. In the best case you’ll be unable to send emails to valid addresses, or find incorrect ones until this block has been lifted. If you don’t, your email could be subject to the most severe blocking, or permanent blocking by the ISP If you don’t adopt measures.

How sending to bad addresses Impacts the ability to deliver

The reputation of your sender is a key element that the majority of ISPs look at when making decisions about how to proceed with your newsletters. Sending out newsletters to inactive email addresses is among the issues that can ruin the reputation of your sender. Other complaints include spam from recipients, as well as a large bounce rate.

The email addresses of bad senders are scrutinized by ISPs in order to detect fraudulent senders since it is a typical tactic used by spammers to distribute emails to large mailing lists, without checking if the addresses are legitimate or not.

If an ISP detects that a certain amount of messages sent by the same sender are sent to addresses that aren’t valid It places an interim block. The percentages that trigger temporary blockages with ISPs differ. ISPs don’t disclose their thresholds to make it difficult for spammers to change the size of their lists to stay clear of blocking. This is a security measure.

Are you a target for an interim block?

If you maintain your mailing list tidy and delete the bad addresses as soon as the bounced emails and bounce back, you won’t experience the temporary blockage at your ISP.

The main categories of marketers that could be the users of temporary blocking due to invalid email addresses include:

Marketers who make use of poor email acquisition techniques to build their lists without much consideration to the quality of their email.

Marketers who regularly send old lists in an attempt to re-engage subscribers who have been inactive.

Marketers who recently switched email providers but didn’t follow efficient or consistent hygiene on their lists.

How to minimize the risk of being temporarily blocked for inactive emails

By following these easy but crucial guidelines, you can lower the possibility of temporary block for invalid addresses and boost your ability to deliver emails:

Get the email collection process. This is where you must begin with. Don’t bother with harvesting or purchasing email lists. Create a sign-up form on your site and let users opt-in themselves. Ideally, you should set up the process with a double opt-in option to ensure that you do not send out incorrect or misspelled emails. Add an email confirmation field on your registration form if you’re using an opt-in procedure that is single to block and catch mistyped email addresses.

Check old lists. If you haven’t sent an email the list for one year or more It’s a good idea to verify the emails from years ago for legitimacy prior to sending an email to them. At the very least, you’ll find a few dead emails that are on your list.

Remove bounced email addresses from your list. Be sure to check your email for bounced messages and then remove inactive emails from the list following one bounce. Create separate mailboxes for bounced messages so as not to confuse bounces with regular emails. You can then use that mailbox as the “Return mail address” in your email sending software. This will allow you to keep bounces in an additional mailbox which you’ll regularly check and eliminate invalid email addresses out of your databases.

The above methods require consistent work and a lot of patience. It may take several weeks for the process to be set up. up the process up based on how large the list you have. But, it all begins with the registration process. It’s a waste of time and effort trying to cleanse your email lists of spam in the event that you do not avoid the risky methods of collecting emails.
