BounceCheck from MailNinja is an email cleaning and verifying tool.
What we check for
Is the email addresses domain name registered and verified? Our Data Verifier tool will look up to see if the associated domain name is registered. If not, the email address does not exist.
Valid syntax / Format check
Is the email address real? We scan the addresses in your list to check the syntax – i.e. does the address contain an ‘@‘ sign, close with a .com or other domain extension, contain valid characters etc.
Gibberish Email Address
We check to ensure the address doesn’t look like a random email address. For example, firstname.lastname@example.org doesn’t pass the test.
Disposable Email Address
We check if the email address has a domain name used for temporary email addresses.
Presence of SMTP Server
This check is successful if we are able to connect to the SMTP server (indicated in MX records).
We test the email address and see if it bounces or not.
We check if the server has a catch-all policy which accepts all the email addresses.
Remove role-based emails
Role-based addresses are typically company addresses defined by a job rather than a person, and are often managed by several people or eventually fall into disuse. Some of these types of addresses are associated with high bounce rates and spam complaints.
Remove webmail provider emails
Our verifier can scan and remove email addresses containing Gmail, AOL, Yahoo, Hotmail domains.
Remove duplicates and empty rows
Removes duplicate email addresses without the need for Excel.
