[...] The other tool that I tried was GMass. It felt a lot more complicated. I didn't like that I had to install two pieces to get it to work - an extension to my Chrome browser plus an add-on to Gmail. Each of those added buttons which are there all the time. Then I wasn't able to preview the merge to make sure that my merge fields worked correctly. What I liked about Mailmeteor is that I could send emails in a few minutes, using the tools I'm already familiar with. It felt very natural to me.
