What is email verification?

First and foremost, email verification is a method of verifying whether an email address is valid or not. And for that, you need an email verification service, which checks each email address in your list and removes all invalid and unsafe emails.

If you are an email marketer and want to run a successful email marketing campaign, then you should validate your email list before hitting the “Send” button. An email verification service can quickly identify and remove all the invalid, fake, disposable, role-based, and duplicate email addresses from your list and provide a fresh and hygienic email list.

Why is it vital to use email verification services?

There are many reasons why an email address may turn invalid or stop working. Sometimes, it may be due to behavioral factors (i.e., a person changing their email address) or certain technical glitches.

Below are a few common reasons why email addresses might become invalid

• Your recipients change their email service/ provider
• Your recipients change their email ID within the same email service provider
• Your recipients switch their positions within a company
• Your recipients change their jobs
• The domain is dead

As you can see, verifying your email lists before hitting the “Send” button” is essential. By using an email verification service, you can improve the performance of your email campaigns. An email verification service helps you:

• Lower bounce rate by removing non-existing, misspelled email addresses
• Scrub your email database to help you collect valuable data about your leads
• Analyze your email headers to ensure your mail server is set up and configured correctly
• Monitor your IP and domain reputation and notify when they are listed on a blacklist
