Trying out @postmarkapp for my next react app blog and wow they have much better dev. experience than @SendGrid. Very clear & step-by-step.

Postmark makes it easy for us to handle all our outbound emails with a high degree of reliability and easy way to get insights into what messages are working with our customers (via tags and analytics).

I SERIOUSLY LOVE YOU! I am not kidding. Other provider's mail would often end up in spam or the service would be very confusing. One team, cohesive product, HUMANS! What's not to love. Keep doing what you're doing!

I came from Mailgun and left because too many emails went missing. Now, my email shows up instantly for people and the amount of time I save on support requests is worth it. A+ quality service.

Love the fact @postmarkapp are publicly sharing their status and deliverability details.

You go above and beyond to make sure your customers understand transactional email. The educational material you provide make me want to use you. But then there is also the fact (which made me seek you out in the first place) that you take deliverability very seriously. You fixed a problem I had with deliverability in Mandrill. An awesome service.

We now send about 100 Million emails a month with Postmark and we couldn’t be more happy with the experience.
