The message

Read back from the chain, 6,400 bytes stored. Original.

One message, two providers, one DKIM signature.

Postmark and Resend each get their own copy of these exact bytes. If the two
stored versions differ, the difference is the provider, not the sender.

Line endings matter here. So does a non-ASCII character: café, Ω, 東京.

This page is disposable. The record is on chain and anyone can serve it from chain data alone.
