The first step to ensure the success of your email campaign is to make sure your emails are delivered successfully. Your email should land in your subscriber’s inbox if it’s to have any impact. ­For this to happen, you need an email list verification tool.


Email list verification is the process of determining whether the email addresses on your list are valid and deliverable. The validity of an email address can be measured through a combination of several validation techniques and internal databases checks with some proprietary algorithms.  These include:

  • Email address syntax check
  • Domain/MX records check
  • Role based Account detection
  • DEA (Disposable email address) detection
  • HoneyPot/Spam track detection
  • SMTP verification and so on

At the end of the list validation process, invalid email addresses are filtered out and you get a clean list for your campaign.

Why is Email List Verification required?

You may have gathered your email subscribers from completely legitimate sources (like the subscribe form on your website) but chances are that not all your email IDs are valid. According to Jupiter Research, more than 20 percent of email registrations contain typos, syntax, domain and other errors. Doing something as simple as sending to an old list where a specific threshold of email addresses bounces can set off your ESPs (Email Service Providers) threshold. And to add to it, bots keep pushing SPAM trap email addresses through systems every day.

Too many bounced mails, trigger ISPs (Internet Service Providers) to block ESPs. To keep themselves safe, ESPs block clients with too many bounced emails. So to safeguard yourself from being blocked or marked as a spammer, it is important that you verify your list before sending out your mass mailer.

How to verify or validate emails?

If your email list has just a few subscribers, you can do it manually by going through each email ID one by one. But chances are your email list extends to thousands of subscribers. Going through each email ID would not only be time consuming and tedious but also be full of errors.

Thankfully, you can automate the process by using Email List Verification tools like MassMailer Email Verifier. You can save yourself from the trouble of going through each email ID, fasten the process of verification, have a clean list and most importantly, have your mails delivered to your subscriber’s inbox.
