The inbox tax
Your best leads are buried under the rest of your inbox.
Replies take attention you don’t have, so the important ones wait — and the lead who emailed at 8am books with someone who answered by 8:05. It’s not a writing problem. It’s a speed-and-volume problem, and that’s exactly what an AI assistant is for.

What your assistant handles
It reads, drafts, sends, books, and files — in that order.
Everything an assistant would do with your inbox, running the moment a message lands instead of whenever you get to it.
Drafts every reply in your voice
Reads the thread, understands what’s being asked, and writes the response the way you would — right length, right tone, your sign-off. The draft is waiting before you open the email.
Knows your business cold
Answers from your real prices, offers, and docs — pulled from your catalog — and never invents a detail it doesn’t actually have. No hallucinated quotes, no made-up policies.
Books meetings on your calendar
When someone wants to talk, it offers real open times, confirms, and puts the meeting on your calendar with an invite — no “what times work for you?” round-trip.
Sends the payment link when a deal locks
The moment a deal is agreed, ReplyOP drops your checkout or deposit link straight into the reply — so you get paid without chasing or switching tabs.
Auto-sends on autopilot
Turn on autopilot and ReplyOP sends the straightforward replies itself — scoped to new threads, set hours, or specific contacts. Anything sensitive waits for your one-click approval.
Re-engages the quiet leads
The thread that went cold after “let me think about it”? ReplyOP follows up at the right moment, in your voice, and stops the instant they reply — so nothing slips through.
Qualifies leads into a CRM
Every contact is read and tagged — hot lead, question, buyer, noise — and pushed into your pipeline so the people worth your time rise to the top automatically.
Checks itself before every send
Guardrails for the things it should never say, plus an injection-proof confidence check on each reply. Anything risky is held for you instead of sent.
API access, included
A read/write REST API and webhooks come with the email tool — pull your replies, leads, and analytics into your own systems, or build ReplyOP right into your product.
Sits on the inbox you already use.
No new app to live in, no migration. Connect Gmail, Outlook, or any IMAP inbox and ReplyOP starts drafting on day one — with a full log of everything it does.
FAQ
Questions, answered.
What does an AI email assistant actually do?
ReplyOP connects to your existing inbox, reads every new message, and writes a ready-to-send reply in your own voice — before you even open the thread. You approve and send with one click, or switch on autopilot and let it send the easy ones itself while it books meetings and files leads.
How does it learn my writing voice?
Paste a few emails you have actually sent. ReplyOP picks up your tone, length, vocabulary, and sign-off, then drafts every future reply from that profile. No tone sliders or templates — it just sounds like you, faster.
Will it send emails without me?
Only if you tell it to. Autopilot has clear modes: draft-only, auto-send when confident, or full autopilot — and you can scope it to new threads only, certain hours, or specific contacts. Sensitive messages always wait for your approval, and every action is logged.
Which email providers does it work with?
Gmail, Outlook, Microsoft 365, Yahoo, iCloud, Proton, and custom business domains. There is no Google or Microsoft approval screen to clear — you connect and start the same day.
