Good service if you are bulk emailing; you don't have to send emails individually; and it checks opens and clicks.

By Rob W.
I wanted to increase users in our team account and got confused when adding users, so I created an individual account for myself again. Thanks to Carlos and Lex my individual subscription got refunded and register with a 10user account without any hassle or delays. Kudos to your support team.

My credit card is stuck with the ex-company email that I no longer worked there. It got charged to renew the plan from the excompany email. With great support, YAMM team helped me to solve the issue right away in 2 days. 5 stars for the customer service.
