How to check email database for validity

7b79e4e8c3e25571bab72910f91f3e18

The effectiveness of email distribution depends on the validity of subscribers’ addresses. A valid email is an email address that actually exists and is assigned to a specific person.

Special services are used to check validity, which will be discussed in today’s article.

Why and when validation is needed

There are two reasons for using validation:

  1. Delivery. When subscriber addresses exist, delivery is increased. This, in turn, improves the reputation of the sender and reduces the likelihood of getting into spam.
  2. Saving. The validity check will detect non-existent addresses – you will not need to pay for them in mailing services.

The validation process itself will be useful when the subscriber base was formed very recently or has not been used for a long time. This is especially useful for cases where the database is collected without Double opt-in – double confirmation of subscription. Or when the addresses in the database are older than 1 year, but there were no newsletters for them, or you have already sent a newsletter and in the statistics you see more than 10% of non-existent addresses.

What to do next

After removing all invalid addresses from your database, you can start a new mailing. However, it is not worth doing this right away, since many subscribers may have already forgotten about you.

It is better to start by sorting the database by the time of adding subscribers. This way you can get a new database of addresses of those users who joined you recently. Make a newsletter for such people. And those who have been with you for a long time – for them it is better to create a separate newsletter with a reminder about the company. Such subscribers should be stimulated, for example, by giving them a pleasant bonus.

This process is called resuscitation, and this is how it is better to do it:

  1. Choose addresses with the date of the last shipment – it is best if the mailing was less than a year ago.
  2. Next, select older addresses and also send them a resuscitation mailing.
  3. Select the next segment of 2 to 3 years and send emails to them.
  4. Repeat the steps until you have gone through the entire subscriber base.

Also, don’t forget the statistics after validating the addresses. There is a good chance that many users will complain about you after a long pause. In this case, you need to analyze everything and take appropriate measures, for example, you can temporarily stop mailing for a certain segment.

Conclusion

One of the key points in checking the validity of addresses is the use of the Double opt-in method, the essence of which is double confirmation of mail. This will protect your mailing from invalid addresses and make it the most effective.

If you did not have the double confirmation method connected at the time of sending, you should check the email database for validity. To do this, use the services we talked about. Yes, you will have to spend a little, but such a contribution will improve the mailing and bring additional income.
