DEVA (Dilli Email Validation API) is a simple REST API to validate the authenticity of an e-mail address without sending a verification e-mail to its owner. Using DEVA, you can integrate email validation in your system, reduce your bounce rate and improve your business reputation.
Test Out Our Email Validator
Some of the factors used to determine validity of an e-mail address are as follows :
- Format Validation : DEVA ensures that e-mail address is valid. Ex : e-mail addresses with missing @ are not valid.
- MX Records’ Existence : DEVA validates that MX records exist for the domain tied to the e-mail address.
- ESP (Email Service Provider) Grammar Rules: Ex : @yahoo.com e-mails cannot have user part less than 4 characters. We learn new ESP grammar rules every now and then and incorporate into our validation algorithm.
- Profanity Check : This is a distinguishing feature of DEVA. It checks e-mail addresses for profanities and marks them invalid if found.
- Patterns : There are countless patterns we discovered while validating over 50,000 e-mails every month for our clients that are obviously invalid e-mails. 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 e-mails having this domain are marked invalid by DEVA.
