Email Validation is a process that checks if an email address is deliverable. In other words, this tool determines if it’s possible to deliver mail to that email address before you send an email.

How Email Validation works

  • All the emails will be validated before sending the email if it's not validated before. There was an option to re-validate the email in 90 days. Before email sending, the validated date will be checked if it is validated before 90 days, re-validation will happen.

Why is Email Validation important?

Email Validation is important because it:

  • Boosts your delivery rate by removing invalid email addresses.
  • Maintains your mailing list hygiene by keeping your email list up-to-date.
  • Improves your email marketing metrics like click-through rate (CTR), open rate, and click-to-open ratio (CTOR).
  • Protects your sender's reputation.

How does Email Validation impact my email deliverability?

Email deliverability is highly impacted by bounced emails. Decrease email bounces by performing email Validation ahead of time.

Your IP address and domain reputation take a hit when your email service provider (ESP) can’t place your email into a subscriber’s inbox. This impacts future deliverability because email clients rely on IP and sender reputations to determine whether or not to deliver your messages. If you have a bad sender or IP reputation, email clients may decide to place emails sent from your domain name in your subscriber’s spam folder. Or, they may not deliver them at all.

When should I validate my email list?

If you’ve bought a mailing list (which we highly recommend that you don’t) or if you’ve inherited a mailing list you’re unfamiliar with. It’s a great idea to use an email verifier.

In addition, if your list has grown or it’s been some time since you last verified your email addresses, we recommend giving your mailing list a health check today.
