MailboxValidator Email Validation Services

 

The Single Email Validation API does validation on a single email address to verify accurately if an email address is valid. It checks for email syntax, MX record, MX server connection, email greylisting, free email, disposable email, suppressed email, role email, high risk email, catch-all email and much more.  Validates your email list to ensure that every email that you sent has a high probability of reaching your targeted customer.

Features

1. Email Syntax Checker-Validates that the email address conforms to a standard format.

2. Duplicate Email Remover-Removes duplicate emails.

3. Free Email Provider Checker – Free Email Provider checker of MailboxValidator checks whether the emails in the list are from a free email provider like Gmail, Yahoo, Hotmail, etc.

4. MX Record Checker – Checks for the existence of mail server records in the DNS.

5. MX Server Connection Checker – Tests for a successful network connection to the mail server.

6. Email Greylisting Checker – Some mail servers use the spam trap to identify the spam email addresses and block them forever to make their mailbox free of spam. So, email greylisting checker of MailboxValidator checks if the mail servers use the spam trap tool or not.

7. Suppressed Email Checker – Checks if an email is in our own Do Not Mail list.

8. Role Email Checker – Checks if an email address is a role email like admin, support, webmaster or sales, etc.

9. Bulk Validation Supported – If you have a huge list of emails then instead of doing the one-by-one email validation, you can do the bulk email validation. Upload the entire file of email addresses and speed up your email verification.

10. Single Validation Supported – Validate a single email instantly and returns all the validation results in either JSON or XML format.
