Why ReplyMill

Every escalation is
a game of telephone.

Support paraphrases the customer. Engineering asks what they actually meant. The customer waits while your team plays messenger. ReplyMill removes the relay entirely.

Customer emails support
Support rewrites it into a ticket

Support goes back to the customer
Three days later, still no answer
With ReplyMill

How replies work

Tickets land in Slack.
Engineers reply
from there.

No new dashboard to babysit. Every bug and request hits the Slack channel your team already lives in — with full context attached. Reply in the thread, or open ReplyMill for more depth. Either way, ReplyMill drafts the customer-ready response so engineers can close the loop without switching hats.

On it — token refresh isn’t resetting cookie expiry on WebKit. Fix is straightforward, pushing to staging now. auth/refresh.ts line 84.

“Hi Sarah — thanks for flagging this, especially with a demo on the line. Our team has identified the issue and a fix is going out shortly. You should stop seeing the logout problem within the hour.”

Tickets post to #eng-bugs automatically. Engineers fix in thread — ReplyMill handles the customer-facing language.
