Support volume is a diagnostic. Every recurring ticket is telling you about a defect in your design, your errors, or your documentation, and the highest-return move is almost always to fix the cause rather than to answer faster.
Categorize your tickets for a month. You will find a handful of clusters: people cannot find their key, people do not understand the auth flow, an error message is unhelpful, an edge case is undocumented, a limit is a surprise. Each cluster has a fix that permanently removes it. An error message that names the invalid field and what would have been valid eliminates an entire category of tickets before they are written.
Then make the answers public and findable. A support answer given privately over email helps one person; the same answer in a public issue tracker or forum helps everyone who searches for the same error string later. Structuring your public issues by type — bugs, experience, features, security — the way InfluxDB does makes them navigable rather than a pile.
And staff it honestly. Support is where a developer finds out whether anyone on the other side actually cares, and it is chronically underfunded relative to how directly it determines whether consumers stay.
