Can I use Mailsend as a Postmark replacement?

Yes. Mailsend's API handles transactional email with the same webhook events, open tracking, and delivery reporting as Postmark - plus marketing campaigns, automation, and segmentation that Postmark doesn't offer.

Is Postmark faster than Mailsend for transactional email?

Postmark has an exceptional reputation for delivery speed. Mailsend's transactional delivery is fast and reliable, though Postmark's singular focus on transactional speed gives them an edge in pure latency benchmarks.
