A Very difficult product. If you don't use the account for 3 days, then they will close the account on the 4th day and ask you to create a new account. You need to have a lot of backup emails in order to use Sendgrid. Another big comedy is about their password rules. It has to be 16 letters. even my bank hasn't asked for such a ridiculous thing. Seems some engineer over there wanted to create some innovation and he just increased the password length. loose guys
Easy to use and hook up, love that you can get a dedicated server for cheap. Analytics leave a lot to be desired as they paywall you for specific user activity beyond 7 days. Pretty affordable.
Easy to use, with good monitoring options and great support for experienced and beginner developers.
The free tier is also a great start for smaller projects.
