Fastest email verification I’ve tried so far after testing zero bounce, kick box and never bounce. Highest free credits too (most are just 100). These guys are 250. Works well. Docs are good enough. Support is decent.

The plugin works on some email fields, e.g. account login, and not on others, e.g. form fields created by Fluent Forms. We found it much easier to install Emailable’s API Widget with its standard configuration. As an email verification service, Emailable is quite good and affordable. However, we would not recommend this plugin for email verification. There are better plugins available on
