Email for Replit apps

Add an email inbox to your Replit app

Give your Replit app its own email address. It can receive email and attachments, show them in your app and reply to the sender. You paste one prompt, and Replit writes the code.

Create your AI agent’s inbox

Copy this setup prompt and paste it into ChatGPT, Claude or another AI app. It walks you through signup and connecting.

How it works

A new email arrives
Someone emails your agent’s address. Revdoku tells your agent right away.

Every read is logged
The audit log shows each email and file your agent opened, and why.
Your agent gets the data
It uses what it found and can reply to the sender.

What your app can do with its inbox

Receive email

Give your app an address for orders, forms, sign-up codes or customer messages, and show new email in the app.

Use attachments

Save PDFs, images and other files sent to the inbox, and use them in your app.

Reply to senders

Reply from the same address to people who emailed your app.

Add an inbox to your Replit app in 5 steps

Create your free inbox. Sign up with Google, GitHub or your email. No card needed.
Create an API key. In your Revdoku dashboard, open Account → Access, create an API key and copy it.
Add the key to Replit as a secret. In your Replit app, open Secrets from the Tools panel, add a secret named REVDOKU_API_KEY and paste your key.
Paste this prompt into Replit. Replit Agent calls Revdoku from your app’s server code, so the key never reaches your visitors’ browsers.

Add an email inbox to my app with Revdoku.
Read the Revdoku API guide first: https://revdoku.com/api.md
- Call the Revdoku REST API only from server-side code
  (a backend route or edge function). Read the API key from
  the secret REVDOKU_API_KEY. Never put the key in browser code.
- Create one Revdoku inbox for the app and save its id and
  email address. Show the address in the app.
- Show new emails and their attachments in the app.
- Let me reply to an email from the same address.
- When a new email arrives, update the app automatically
  (use a Revdoku webhook if the app has a public URL).
Ask me before creating more inboxes.

Try it. Send an email with an attachment to your inbox address and check that it shows up in your app.

Keep the key in Replit’s secrets, never in page code or chat messages. API reference · Plans and limits
