This is a doddle to set up if you read the manual and I have no doubt it will save me tons of cash in the future. I prefer to own my data and this includes everything from emails to analytics. I get peace of mind knowing I can tell my customers exactly where their data is.

It took me less than 30 minutes to set up the server and generate an SSL certificate. Took me less than 2 days to get Amazon approved.

I was using Sendy previously and honestly there isn't anything wrong with Sendy for my use case. My reason for the switch was that we have Beefree included with some HTML templates so I can use it right away without messing about with 3rd party stuff and of course, its lifetime so no more update payments to sendy.

Of course you do need your own server, however that is a good thing. Keeping stuff separate is always a great idea. I had sendy set up on my main server so if that went down, so did my list.

I purchased tier 3 because I do plan on reselling it as a freelance developer as part of my services.

Support is good for the team size, and I didn't need to wait more than a day for an answer (which I found by reading the docs anyway!)

This is a diamond buy. I love that its not a sass, you own your data, its safe. And even at full price of $999 I can see this selling well. I look forward to many updates in the future..

Oh which reminds me... how about 2 factor, it needs to happen! I cant see that anywhere :)
