Your inbox, handled.

Mailon is your helper that answers emails on your behalf. It reads messages in a designated inbox and decides on the next best step - whether that's drafting a response, checking a knowledge base for the information needed to reply, or routing the response to you for review.

AI email agents

Your AI helper agent gets its own email address — separate from your personal inbox — and you can create as many of these addresses as needed.

You stay in control

Nothing sends without you.

Every draft waits in a window you can cancel — 30 minutes by default. Anything the agent is unsure about is escalated to your review queue instead of sent.

Common questions

What people ask before signing up.

What is Mailon?

Mailon is an AI email agent that gets its own dedicated email address on your subdomain — like support@acme.mailon.ai. It reads every incoming message, drafts a reply in your voice grounded in your knowledge base, and sends it after a short cancellable delay. You set the direction; it does the typing.

How does Mailon know what to say?

You give it two things: a short prompt that describes its job and tone, and a knowledge base of reference documents (PDFs, DOCX files, FAQs, price lists). Mailon searches those documents when drafting a reply, cites the source, and never invents answers it can't ground in your material.

Can I review replies before they send?

Yes — every reply waits in a cancellable window (30 minutes by default) before it goes out. You can edit, cancel, or let it send automatically. Anything the agent is unsure about is escalated to your review queue instead of sent.

Does Mailon connect to my existing inbox?

No. Mailon doesn't touch your personal Gmail or Outlook. It has its own dedicated address on your subdomain. You can forward a real address to it, publish it as your support@ address, or use it standalone — your primary inbox is never involved.

What kinds of emails can Mailon handle?

Mailon handles inbound email of any kind: customer support queries, product questions, booking requests, sales follow-ups, and more. You write one prompt per mailbox to define the scope and tone, then attach the relevant knowledge. One agent per use case keeps replies accurate and on-brand.

Is there a free plan?

Yes. You can start for free — your first replies are on us, no credit card required. Connect a mailbox, upload a document, and watch Mailon draft its first reply within seconds. Paid plans unlock higher usage and additional mailboxes.

Can I use my own domain?

Yes. Start in seconds on a free name.mailon.ai address, then connect your own domain whenever you're ready — like support@ai.yourcompany.com. It's a single DNS change; we handle the rest (MX, DKIM, SPF, and DMARC). Custom domains are available on paid plans.
