The importance of email ID validation

Protect your sender reputation by using a valid email check to catch bad addresses. When someone signs up for your email list, Mailgun’s email ID validation service double- and triple-checks that you’re adding a real person to your list.

Hard bounces happen, but a high bounce rate can put your sender reputation at risk. Major inbox providers flag spammy behavior – like sending to invalid email addresses – so running a valid email check can help you catch bad contacts before they do damage.

What’s an invalid email address?

An invalid email address is either improperly formatted or just doesn’t exist. A valid email address, of course, is one that’s properly formatted and does exist. Sometimes the difference is just a matter of filling out a form incorrectly.

Invalid email addresses often contain simple email ID mistakes that can easily be avoided when you verify email addresses with an email checker directly within your email forms.

  • @domain.com (missing username)
  • email.domain.com (missing @)
  • email.@domain.com (leading dot is not permitted)
  • email@domain (missing top-level domain like .com or .net)
  • email@-domain.com (leading dash in front of domain is invalid)

Why every great email marketer needs a valid email check for email verification

Without verifying your emails with an email validator, up to one-fifth of legitimate business emails will never appear in the targeted inbox, which means a lot of wasted effort spent on acquisition, lead generation, email marketing design and execution.

When Email Validation verifies an email address actually exists, you won’t waste money sending to temporary or disposable mailboxes, role-based email addresses (like info@), or bad email formats. Over time, this protects the reputation of your domain and IP address, reduces bounces, and improves deliverability.
