  1. Caveat emptor: with free plans from SendGrid, Mailgun, etc, you have no control over the IP address that’s used to send mail through. These IPs are typically shared, and it’s not uncommon for them to be on someone’s blacklist (especially Microsoft’s, so delivery may be an issue with any Hotmail or Outlook address). I’ve tested almost every transactional email service and ended up using Postmark, which costs $10/mo (minimum), but has proven to be reliable. Plus their customer support is fantastic.
