I have been using YAMM for several years. I am technologically challenged but I like to keep control of my own email list. After answering my questions with patience (many when I was in the middle of putting out a mass email and something did not go to plan) I have been able to use and enjoy the YAMM app and build my company. I especially enjoy grabbing a cup of coffee after the emails have been sent and being able to watch who opens the email. My rate of opening is 45% and I have over 2500 email addresses (a two day send on Google with a 1500 limit). I also like how easy it is to schedule the remaining emails and follow up a few days later with those that have not opened the email the first time around. YAMM is prefect for my small business.

YAMM is an easy-to-use mail merge tool, all integrated within Google Workspace. I use YAMM in a nonprofit setting, so sending personalized messages to other community partners is easy. The YAMM team is also super helpful and supportive. 10/10 recommend.
