Are these two tools competitive or complementary?

Mostly complementary. Linear Customer Requests is the storage and prioritization layer attached to issues. ReplyMill is the inbound + reply layer. Many teams use ReplyMill for email/Slack triage and forward the highest-demand clusters into Linear.

Does ReplyMill push into Linear?

A native Linear push is on the roadmap. Today, you can copy ReplyMill cluster URLs into Linear issues manually, or use Linear's email-to-issue feature on a separate alias.

Can Linear send replies to customers?

Not directly. Customer Requests stores feedback but doesn't reply to the customer. If a customer emails you, someone needs to reply from somewhere — that's the gap ReplyMill fills.

Why not just forward email straight to Linear?

Linear's email-to-issue is a one-way pipe. ReplyMill threads incoming email, groups by topic, drafts replies, and tracks status. The reply loop is the part Linear isn't built for.

Do I need a paid Linear plan to use ReplyMill?

No. ReplyMill works standalone. If you also use Linear, the two compose well; if not, you still get the inbound and reply benefits.

Pick Linear Customer Requests when…

•You already live in Linear and the goal is to weight requests against existing issues.
•Customers send feedback through a public portal or someone manually files it for them.
•You don't need to reply to the customer from the same surface that captured the feedback.
•You're happy to bring your own inbound layer (email, support form, etc.).

Pick ReplyMill when…

•Customers email you and you need a way to capture, group, and reply — not just file feedback.
•You want AI drafts so engineers can close the loop without writing every reply from scratch.
•Slack is where the team works, and routing each request into a thread is the path of least resistance.
•You'll eventually pipe high-demand signal into Linear, but you need the inbound layer first.
