Email Verification Service
Email checker – The easiest way to verify email addresses
Check if an email address is valid or not with Mailgun's fast and simple email verification tool. We send billions of emails every month and use this data to build the fastest and most accurate set of email verification data available.
Protect Your Business
A bad email address is a lost customer
Over 20% of your email database will go bad this year. Invalid email addresses result in unnecessary bounces, drive down your engagement metrics, damage your sender reputation, and cost you money.
How much time and money are you wasting on bad leads?
Mailgun’s entire business is sending emails. We send more than 250 billion emails every year, so we’ve hashed the majority of active email addresses. We know what’s deliverable and what’s not.
Plus, our quick Email Verification software is part of an integrated suite of deliverability features and services. You don’t have to worry about wasting time and effort switching between different platforms and data sources.

When verifying large contact lists, get your results in minutes instead of hours or days. Need to clean a list with millions of addresses? Walk to the breakroom, grab a cup of coffee, and come back to a clean email list.
Protect your platform from abuse without sacrificing performance
Bot attacks can turn into full-blown DDoS attacks if detected too late. Are your users trying to trick your platform with grammar rules? Our email checker flags that information too.
List verification feature
Clean your subscriber list of invalid emails before you hit send. Our list verification feature is as simple as uploading a .csv.
Not sure whether your list needs a clean? Run a list preview. This email tester is a version of our Email Verification feature and can help you assess a statistically significant sample of your list so that you can decide whether you need to clean the rest.
