Pros & Cons from Real Users

Pros

  • We used the email verification and validation API to prevent spam sign ups on our ecommerce site and Abstract what a great match for us. The responses were faster and more accurate than other options we tried. Since Abstract offers other API's like IP geolocation we were worried about not having a specialist provider, but Abstract really was excellent. And now we are using more of their API's.

Cons

  • They didn't have many different pricing plans at first, but eventually we worked with them to get a price that worked for us.
