Review on Postmark by Seth Gomez

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 network level etc., Also sometimes there's issues where images don't display properly after being sent out via postmail; however these are rare occurrences &amp has always been able resolve them quickly once contacted by support team member who then works closely wth client developer teams until issue resolved successfully.- Sending mass updates- Mass communication tools.
