Get Started FreeEmail bugs are hard to reproduce
Disappearing evidence
By the time you report the bug, the email is buried in someone's inbox or deleted.
"Cannot reproduce"
The classic developer response. Without the exact email, debugging is guesswork.
Missing context
Screenshots don't show headers, raw HTML, or why the email looks wrong.
Back-and-forth
Endless Slack threads asking for more details about the broken email.
