Replies to bug reports: templates for every situation
Short replies for thanks, need more details, fixed, can’t reproduce and won’t fix, so every report gets an answer without sounding canned.

Short answer: reply to every report, quickly, in a sentence or two. Say what happens next. A clear reply tells the reporter what your team needs and what happens next. Personalize the first line and the templates below do the rest.
Thanks, we’re on it

Good news: this is fixed in {version / today’s update}. Could you try {action} again and tell me if it works now?Can’t reproduce yet
Template
Thanks. We tried {action} on {device/browser} and couldn’t make it happen yet. If you see it again, could you send another report from that screen? That gives us the details we need.Not planned, for now

Thanks for the idea. We’re not planning this right now because {short honest reason}, but I’ve added your request so we can see how many people ask for it.See also: closing the loop on user feedback
