Common migration questions
Will my Postmark Message Streams work?
Yes. Mailazy supports separate transactional and broadcast streams with their own reputation tracking. Map Postmark streams 1:1 during migration.
Does Mailazy match Postmark's delivery speed?
Yes. Median time-to-inbox is under 5 seconds for transactional sends. We use the same priority routing approach.
What about Postmark's MJML templates?
Mailazy supports MJML import directly — paste your existing templates or use our visual editor. Same responsive output.
Are bounce categories the same?
We use the same RFC standard categories (hard/soft/spam/transient). Postmark webhook payload mappers are available in our SDK.
Is there a sandbox / test environment?
Yes. Every account has a test API key that captures emails without sending. Free tier includes 1,000 test sends per month.
