Questions about Email Verification Use | Email Verification API | WhoisXML API


Can your email verification tool quickly detect fake email addresses?

Yes. Our email verification products can thoroughly validate email addresses almost instantly via API calls or lookup queries. Simply type in the email address you want to verify, and you will see the verification details within seconds or minutes (for bulk lookups).

I have a long list of email addresses to validate, how do I do that?

You can validate up to 50,000 email addresses in one go using Email Verification Bulk Lookup or Email Verification Bulk API. Upload your email list in comma-separated values (CSV) format and download the verification results in CSV (for the lookup tool) and JavaScript Object Notation (JSON) or Extensible Markup Language (XML) format (for the API).

Aside from disposable email addresses, what other things does your email verification tool check?

Our email validation products check if the email address was created using any of 2,000+ disposable email services, including GuerillaMail and 10MinuteMail. We also perform the following analyses on every email address you want to verify:

  • Check if the email address contains syntax errors
  • Perform an email-sending emulation technique to see if the email address can receive messages through the Simple Mail Transfer Protocol (SMTP)
  • Check for misspelled and curse words
  • Make sure that the email address has corresponding Domain Name System (DNS) mail exchanger (MX) records
  • Check if the email address is a catch-all

Can I download a list of disposable email domains?

Yes, you can. We have an extensive list of disposable domains that are mainly used for fake and one-time email addresses. You can learn more about it here.

Do you provide a free trial email verification plan?

You can have 100 free API requests every month on our Email Verification API when you sign up.

How do your email verification products differ from others?

Our email validation process is extensive. It involves checks for syntax errors, mail server existence, and mailbox existence.

Our email verification service can be accessed via an easy web-based lookup tool or an integrable and widely compatible API. We have client libraries for our Email Verification API to reduce the amount of coding required on your end.
