Make calls wherever you are


Receive (customer service) calls in one team inbox

Often your customer service may have contact with a client in different ways. For example: a client may send an email and calls you subsequently to get a direct answer to his question.

Trengo can match a call with an email address in the corresponding client profile. You know immediately who your client is and how he contacted you. It gives you a clear overview and prevents extra work.
