Postmark Review

I like that they have several different options to send emails from as well - we use it for our newsletters but also their API allows us access into other third party services (like MailChimp) which makes things easier than having multiple accounts set up! Sometimes you get errors when trying sending larger files with attachments so make sure your server can handle large file sizes otherwise this could be problematic if working within certain size limits or bandwidth restrictions at work/home…
