Great but very bad at the same time
The idea of this plugin is really great.But unfortunately t goes to scr*w up the link/email/page of the lost password.So that when a user forgets the password will be never ever able to get the change
This is a Great Plugin
Works great! Using it to replace the default WordPress Email.
Way better than using built-in / server email!
This plugin is super easy to use and connect to whatever email service you are already using. Much better than the built-in / server-side emails that WordPress defaults to. Thank you <3
