Migration Guides

Two months since I switched from @SendGrid to @postmarkapp and deliverability/time to inbox has been significantly better. Plus, Postmark's support team is fantastic! Highly recommend using @postmarkapp for your transactional emails.

Currently switching over all my transactional email to @postmarkapp. Great experience so far – awesome job, guys!

Postmark blows every other transactional email product out of the water.

Every time I integrate @postmarkapp with an app I find myself thinking how great the onboarding is. So refreshing.

Postmark ensures that the mail from our customers gets delivered to their customers.

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

Postmark has made it easier to help our customers because of its accessible and detailed activity log which means we get better information faster.

We've architected our sending infrastructure to rely heavily on Postmark, and we couldn't be happier. They've been supportive at every step along the way, and have helped us to deliver (and report on) tremendous results for our clients.

Before Postmark we were using SendGrid, but we had lots of problems with the IP reputation, and they wouldn't move us to another IP range. So we decided change providers, and we are very happy with Postmark.
