How DEVA validates an email address?
- Format Validation : DEVA ensures that an email address has a valid format. Ex : validusergmail.com is invalid email address because its missing the ‘@’ before the domain ‘gmail.com’.
- MX Records : An email address with a domain that does not have an MX record in its DNS settings is invalid. Ex: user@domainWithNoMXRecord is invalid. DEVA finds if MX records exists for the domain tied to an email address. If no MX records exist, the email address is reported as invalid.
- Disposable/Temporary Email Address detection : DEVA maintains a list of throwaway/disposable email addresses or junk collector email addresses and validates emails against this list. Ex : email@example.com will be invalid.
- ESP (Email Service Provider) Grammar Rules: Ex : @yahoo.com emails cannot have user part less than 4 characters. We learn new ESP grammar rules every now and then and incorporate into our validation algorithm.
- Spam Email Address detection : DEVA has access to a gigantic third party database of email addresses known to spam. It queries this database to determine the validity of an email address. Ex : firstname.lastname@example.org is one such email address that is known to spam.
- Profanity Check : This is a distinguishing feature of DEVA. It checks email addresses for profanities and marks them invalid if found.
- Role Based Email Address detection : DEVA detects generic group role based email addresses like info@, support@, store@, etc and marks such email addresses as invalid.
- Patterns : There are countless patterns we discovered while validating over 50,000 emails every month for our clients that are obviously invalid emails. Ex : email@example.com, firstname.lastname@example.org, email@example.com, etc. DEVA is constantly learning and building up the black listed patterns as our user base grows.
- Blacklisted Domains : Ex: example.com is reserved and can’t be used in practice. Therefore, all emails having this domain are marked invalid by DEVA.
- Custom Blocklist : You may request certain valid domains, emails and users to be blocked. For example: A site may never want any mail.ru email address to be used on their site due to the higher probability of it being a malicious email address. We can add such custom requests to your validation.
Note: You may request to disable any of the above filters when validating with DEVA.
