Just tried out @postmarkapp and boy is it blazing fast. Transactional emails that previously took 5-10s to reach my inbox with Mailgun are now hitting my inbox in less than 1s.
11/10 would recommend.

I’ve had great success with @postmarkapp and the API is solid as gold.

Sendgrid = Frustration
Postmark = 💌
– Mike Verbruggen
Ripped out Sendgrid and moved Growform's transactional emails over to @postmarkapp today.
Their app is ridiculously easy to use, they have a clear focus on deliverability and great docs. Highly recommend so far.
– Harvey Carpenter
I just implemented @postmarkapp in like 5 minutes. Email received in Yahoo in seconds. I am sold.

I have nothing but huge love for Postmark, one of my heroes in the bootstrapped world.
– Anna Maste
Spent the weekend shifting @SeshMysteries across from SendGrid to @postmarkapp and couldn't be happier with the experience so far ✨📩
– Dan Foster
Been a postmark customer for a veeeerry long time. Stability and deliverability is so good I sometimes go months without thinking about it… just works(tm).
– Ben Webster
I’ve been so impressed with @postmarkapp since migrating almost all Smart Order Notifications transactional email to them last month. The peace of mind is amazing and the responsiveness of their support team is next level.
