Turn a bot email into a working inbox app

Grok Bot can set up and publish a mailbox app for a bot address, then return the live link and password.

Done with Grok Bot· Intermediate· Oct 2026

What they did
A developer made a Grok Bot template that starts by asking the user to grant access. Once approved, it uses the user’s Vercel and Supabase accounts on free tiers to create a mail app for the bot’s address ending in @mail.grokbot.com. The agent takes over the address, builds the database, publishes the app to the user’s Vercel account, adds syncing, tests the setup, and then sends back the link plus password.
How it went
The first build finished in 23 minutes with no code written by hand. The finished app worked on desktop and phone and included inbox, sent mail, drafts, archive, trash, starred messages, automatic sorting, search, composing, replies, and code extraction from emails. The post says replies wait for the next sync, and xAI had not shared limits for bot email sending or storage.
Tips
Expect to handle the account approvals yourself before the agent can proceed. Your mail data stays in your own Vercel and Supabase accounts, not in the template maker’s.

Try it yourself with Grok Bot

Help me create a mail app for [bot address]. Start by listing the access and account connections you need, and stop until I approve them. After I confirm, use my [Vercel] and [Supabase] accounts to build the app, set up the database, add syncing, and verify that it works. Before any action that would send mail, erase data, or submit changes, pause and ask me to confirm. When you are done, give me the live app URL, the password, and a short rundown of what was created.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
