All five route to the same human — the subject just helps us reply faster. Each card has its own “what to include” tucked underneath.

01 / 05!bug report
Found something broken? Send the receipt.

Paste the exact input, the tool URL, the browser, and what you expected vs. what you got. The more specific, the faster the fix — most bugs ship a patch within a day.

02 / 05+feature idea
Got an idea for an existing tool?

Lead with the problem ("I keep doing X across three tools"), not the solution. We've shipped most reader-suggested features within a week.

No agenda? Still welcome.

Saying "this saved me at 2 a.m." is genuinely the best email we get. No need for a subject — just write.

A glimpse at the other side.

The actual inbox is private — but here's the rhythm of a typical week. Mostly bug reports and tool ideas, the occasional “just to say hi.”
