MailboxValidator Mobile App



We have recently introduced our MailboxValidator mobile app for the Android and iOS platforms. This free tool can quickly validate an email address without the need to sign up or register for anything.


Credits to perform queries

This app works on the simple concept of credits. Each credit enables you to perform 1 email validation. Upon installation, you’ll get 20 free credits. You can immediately use these 20 credits if you so wish. Upon finishing these 20 credits, you’ll have to wait another day to get another 5 free credits. As long as you have the app installed, you’ll get 5 free credits per day up till a maximum of 100 credits.


Validation results

The app will return some results like the below:

  • Verified Status
    • This is the summary to say if the email address is valid.
  • Domain Exist
    • This indicates if the mail server record exists in the DNS.
  • Server Down
    • This is the checking for non-responsive mail servers.
  • Free Email
    • This indicates if the email address is from a free email provider like Gmail.
  • Syntactically Correct
    • This indicates if the email address conforms to the standard email address format.
  • Disposable Email

  • Contained High Risk Keyword
