A short prompt sets the job and the tone. Support sounds like support, sales sounds like sales — on brand, every time.
It answers from your docs, price lists, and past replies, and cites where it found the answer. It paraphrases your sources — it doesn’t invent them.
Replies use the full conversation, so follow-ups land in context instead of starting from scratch.
Anthropic Claude, OpenAI GPT, or xAI Grok. Pick one per mailbox, override it per prompt, switch whenever you like.
Every reply waits in a review window you can edit or cancel before it goes out.
Out of scope or unsure? The agent hands it to your queue with a suggested draft instead of guessing.
A two-stage filter — fast header checks plus a lightweight model — clears the junk before it ever reaches a reply.
Pause a mailbox to keep logging mail while auto-replies stop. Pick it back up in one click.
PDFs, Word files, spreadsheets, Markdown, web pages — drop them in. Scanned documents are read with OCR automatically.
Point Mailon at a URL and it turns your website into clean, searchable knowledge. Re-crawl whenever it changes.
Semantic search means the agent surfaces the answer even when the wording doesn’t match — no exact keywords required.
Keep one knowledge base for the whole team, then choose exactly which documents each mailbox can see.
Edit the agent’s instructions with full version history, and roll back any time.
Run two prompts at once with traffic weights and watch which one writes the better replies.
Try a prompt against a sample email and see the exact reply, the tokens, and every step the agent took — before it ever goes live.
Every reply, spam call, and escalation is logged with its complete transcript, so you can see precisely why the agent did what it did.
A real, sendable address on your subdomain — like support@acme.mailon.ai. Forward to it, publish it, or point your existing support@ at it.
Bounces and complaints feed suppression lists automatically, with one-click unsubscribe and STOP handling, so your sending reputation stays intact.
Google, Microsoft 365, or email and password. Accounts on the same email link up automatically.
Every reply, crawl, and lookup is metered, so what you use is exactly what shows up — no surprises.
Connect a mailbox, upload a doc, watch Mailon draft its first reply. No card required.
