The only difference here is that I’ve seen more mentions of Postmark having faster delivery rates. It’s clear that Postmark is dedicated to providing a terrific transactional email sending experience, but because of this, it lacks email marketing features. So, if you want fast delivery speeds and high inboxing rates for your transactional emails without any extra features, go with Postmark. Need to send both transactional and marketing emails, even at the same time, without compromising your deliverability? Don’t look further than Mailtrap.
