How to Check an Email Address With the Free Email Verification Tool

Whether your customer list is large or small, checking every email address by hand is not realistic. Some people mistype an address, others hand over a throwaway one just to get past a form once - both look exactly like a normal email address, and the only way to tell the difference is to actually verify it.

What a good verification tool actually checks

Just seeing an @ sign and a dot is not enough. A real verification looks at whether the domain has MX records (meaning a mail server is actually configured to receive mail there), whether the domain belongs to a known disposable/temp-mail service, and whether there is a common typo in a popular webmail domain - all checked together, not one at a time.

How to check it step by step

1. Paste the email address you want to verify into the checker box.
2. Click Check - within a few seconds the syntax, MX records, and disposable status are all shown together.
3. Look at the resulting score and the individual signals to judge whether the address is real and reachable, rather than only reading pass/fail.
4. Use the bulk upload option if you need to verify a whole list of addresses at once.

How much the free version covers

A limited number of email checks are available for free every day with no signup required - plenty for a small list or the occasional one-off check. For a larger list, Premium removes the daily cap.

Reading a borderline result

Not every result is a clean valid or invalid - a domain that accepts all mail regardless of the address (a catch-all) or one missing just a single authentication record shows up as medium risk rather than a flat pass or fail, and is usually still fine to send to, just worth a second look for a high-value message.
