My experience with Vergify so far has been great.
The best thing about this software is the amount of features you get with one app. Before I was using an app for live chat, a different one for email marketing, a different one for handling my support tickets and then a CRM for managing my clients. Vergify offers all of this. This is helpful and saves me time.
They support reading and sending emails through the app, however they do not support yahoo email accounts, only gmail, office 365 & outlook.
Thanks Clive, we're happy your experience has been positive.
