HUGE FAN of YAMM, have been using for years! Best mailmerge tool out there. This tool has been pivotal in the operations of my business. It's very user-friendly, so everyone from the most advanced technical users to those who are less comfortable with technology have been able to use the tool with ease. This is important as team members often have variable levels of degree of technical know-how. I really love the ability to see the status of the sent emails, whether they've been opened or even clicked.
