The email tool
An AI that writes like you
Because it learned from you — and it actually knows your business.
Overview
Most “AI email” tools help you write faster. ReplyOP writes the first draft for you. The moment a message lands it reads the whole thread, works out what the person is actually asking, and produces a complete, ready-to-send reply in your voice — before you ever open the email. You stop starting from a blank box and start from a finished draft you can send or tweak.
And because it works from your real prices, offers, and docs, the reply isn’t generic filler — it moves the conversation forward the way you would. If it’s missing a detail it’s designed to ask rather than guess, a safety check reviews every draft, and nothing leaves your inbox until you approve it (or you switch on autopilot).
What you get
Drafts every reply in your exact voice
Paste a few emails you’ve actually sent and ReplyOP picks up your tone, length, and sign-off — so replies are written to read like you typed them, not like a template.
Knows your business cold
Answers from your real prices, offers, and docs, pulled from your catalog — working from facts you’ve given it instead of guessing, with every draft yours to approve.
Reads the intent on every message
Tells a price question from a booking request from a “just looking,” and replies accordingly — pulling out the question, contact details, and next step.
Works with any email inbox
Gmail and Outlook connect in one click; Yahoo, iCloud, Proton, and any IMAP inbox connect with an app password. ReplyOP only ever touches the conversations your customers send you.
Streaming drafts
Tokens appear as the AI writes them — no “loading…” spinner. You read the reply as it forms, then send it or tweak it.
Always yours to edit
Every draft waits for you. A rich-text composer with bold, links, lists, and your real signature — not plaintext.
Trained across industries
Agencies, coaches, real estate, med-spas, ecommerce, consultants — it has seen the conversations your business actually has.
API access included
A read/write REST API and webhooks ship with the email tool — pull your replies, leads, and analytics into your own app, or build on top of ReplyOP.
How it works
From a new message to a sent reply.
- 01
Learn your voice
Paste a handful of emails you’ve actually sent. ReplyOP extracts your tone, sentence length, vocabulary, and sign-off into a reusable voice profile — no tone sliders, no templates to fill in.
- 02
Read every new message
As each message arrives it reads the full thread, pulls out the real question, the contact details, and the next step, and classifies it — so the leads worth your time rise to the top instead of getting buried.
- 03
Draft in your voice
It writes a complete reply, streaming in as it goes, working from your catalog and docs rather than guessing at a price or policy. What you read is meant to sound like you typed it.
- 04
You send — or it does
Approve with one tap, tweak it in a rich-text composer with your real signature, or switch on autopilot and let it send the confident ones itself while it books and files the rest.

FAQ
Questions, answered.
Will it actually sound like me?
It learns from your real sent mail, not a generic template, so the drafts are written to read like you wrote them. You can edit any draft, and you approve each one before it goes out — so you stay the final word on tone.
Which email providers does it work with?
Gmail and Outlook connect in one click. Yahoo, iCloud, Proton, Microsoft 365, and any other IMAP inbox connect with an app password. There’s no Google or Microsoft review screen to clear — you connect and start the same day.
Can it make up prices or facts?
It’s built not to. It works from your catalog and docs, stays grounded to the thread, and a safety check reviews every draft. If a detail is missing it’s designed to ask rather than invent — and because you approve sends (unless you turn on autopilot), you’re always the final check. Like any AI it isn’t perfect, which is exactly why the review step exists.
How long does setup take?
A couple of minutes: connect your inbox, paste a few emails you’ve sent so it can learn your voice, and it starts drafting on the next message that arrives. There’s a 7-day free trial to try it on your real inbox.
Does it only handle sales email?
No — it drafts any reply in your voice: client questions, scheduling, support, follow-ups. The lead scoring and CRM sit on top for the threads that are actually leads, so the rest just gets answered.
