EmailDetective – A Email Validation API▲6
Hello, I'm Andrew, owner of EmailDetective. I was looking for an API solution for email validation/scoring for multiple mailing lists. I noticed a lot of the email validation services out there: - Do not have an API - Are behind a paywall to try the API - Are priced way to high - Have inconsistent or non-intuitive APIs So I decided to create my own solution. This is my first time announcing EmailDetective, so I am looking for any general feedback, issues you might have run into and if you find this service useful. And yes you can try it out for free without signing up :)
