YAMM is a great program for easily sending batch emails. It’s smooth and has a simple report to track opens, clicks, and replies, so you know who you’re reaching. I’ve been using it forever a few years now. The free version is good enough for shorter lists and the upgrade is inexpensive while opening a bunch of other options. Highly recommend.
