This has made my work life so much easier. Before I downloaded YAMM, I would spend hours sending individual emails to each student. YAMM allows me to send personalized emails to my students in minutes, which increases response rates. Their costumer service is awesome!

Perfect customer experience, quick, warm, efficient. We’ve just switched 4 individual accounts to a Team one in less than couple of hours with all the refunds for the unused license periods. - All the added features (Polls, Filtered lists) help a lot for RSVPs activities. - EU invoicing. Happy “4yrs old” customer
