Features

Everything a mailbot needs to run your inbox.

Mailon gives you an AI agent with its own address that reads every message, decides what to do, and replies in your voice — grounded in your knowledge, and never out of your hands.

The agent

Replies that sound like you

In your voice

A short prompt sets the job and the tone. Support sounds like support, sales sounds like sales — on brand, every time.

Grounded in your knowledge

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.

Reads the whole thread

Replies use the full conversation, so follow-ups land in context instead of starting from scratch.

Your choice of model

Anthropic Claude, OpenAI GPT, or xAI Grok. Pick one per mailbox, override it per prompt, switch whenever you like.

Human-in-the-loop

You stay in control

Nothing sends without you

Every reply waits in a review window you can edit or cancel before it goes out.

Escalation queue

Out of scope or unsure? The agent hands it to your queue with a suggested draft instead of guessing.

Spam, filtered

A two-stage filter — fast header checks plus a lightweight model — clears the junk before it ever reaches a reply.

Pause any time

Pause a mailbox to keep logging mail while auto-replies stop. Pick it back up in one click.

Knowledge base

Knowledge it can actually use

Upload your docs

PDFs, Word files, spreadsheets, Markdown, web pages — drop them in. Scanned documents are read with OCR automatically.

Crawl your site

Point Mailon at a URL and it turns your website into clean, searchable knowledge. Re-crawl whenever it changes.

Finds the right passage

Semantic search means the agent surfaces the answer even when the wording doesn’t match — no exact keywords required.

Scoped per mailbox

Keep one knowledge base for the whole team, then choose exactly which documents each mailbox can see.

Prompts & testing

Tune it like a teammate

Versioned prompts

Edit the agent’s instructions with full version history, and roll back any time.

A/B test in the open

Run two prompts at once with traffic weights and watch which one writes the better replies.

Test before you ship

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.

Full audit trail

Every reply, spam call, and escalation is logged with its complete transcript, so you can see precisely why the agent did what it did.

Production-ready

Built to run for real

Its own address

A real, sendable address on your subdomain — like support@acme.mailon.ai. Forward to it, publish it, or point your existing support@ at it.

Deliverability built in

Bounces and complaints feed suppression lists automatically, with one-click unsubscribe and STOP handling, so your sending reputation stays intact.

Sign in your way

Google, Microsoft 365, or email and password. Accounts on the same email link up automatically.

Usage you can see

Every reply, crawl, and lookup is metered, so what you use is exactly what shows up — no surprises.
