Email excellence vs multi-channel breadth

Postmark is legendary for transactional email. They've optimized everything for deliverability and built a reputation for reliability.

Sendivent takes a different approach: handle all notification channels adequately rather than one channel perfectly.

When email-only is right

If email is truly your only channel and deliverability is critical, Postmark is hard to beat. Their focus shows in:

  • Industry-leading delivery times
  • Excellent sender reputation management
  • Detailed delivery analytics

When multi-channel matters

Most products eventually need more than email. When that happens, you either:

  1. Add more providers alongside Postmark
  2. Use a multi-channel platform like Sendivent

Option 2 is simpler but trades Postmark's email excellence for channel breadth.

The honest comparison

Postmark is better at email. Sendivent is better at doing email plus everything else from one place. The question is which tradeoff fits your product.
