Improve Your Deliverability

Implement an email validation service in real-time

Invalid email addresses result in unnecessary bounces, drive down your engagement metrics and sender reputation, and cost you money. Use an email validator tool to proactively protect your reputation and boost your delivery rates. Also, with email validation, you won’t waste your budget on email addresses that don’t exist. 

Usually, the easiest way to build a list and verify emails at the same time is through a web form. When an email validation tool is not in place, users may enter invalid email addresses, spam traps, or disposable mailboxes. If you send a bulk email without an email verification process your messages end up bouncing, and your sender score and email deliverability both end up suffering for it.

A study showed that sender reputation led to nearly 75% of all email delivery problems. With a solid validation process, your organization gains a strong sender score with top Internet Sender Providers (ISPs), so your IP addresses and domain names have a positive reputation. Email validation will increase your delivery rates so more of your emails can make it to the inbox. 

How to validate emails with a verification service

Partner with an Email Service Provider (ESP) that offers an email verification tool. Usually, there are two methods of validation:

  • You can either validate emails at sign up to make sure you are capturing good data. Or, with a real-time email validation API, verify email addresses in real-time at the point of capture to reduce invalid email addresses submitted through newsletters forms or online registrations forms.

  • You can also clean your email list periodically to make sure it stays that way. A bulk list validation tool will help you clean your subscriber list of invalid emails before you send. It can be as simple as uploading a .csv file and checking the list. List cleaning should be done at least every 6 months to ensure your emails are still valid.


Customers who validate email addresses before they send have a 21% lower bounce rate, which drastically improves their inbox placement.



Pro Tip

Address validation can make the difference between a successful email marketing campaign and an underperforming one. When you make sure your message is reaching valid emails with an email address validator, you’ll see a dramatic rise in your deliverability.
