📝 Email automation for OpenClaw
@openclaw is everywhere right now.
And one of the most requested use cases is email.
This guide shows you how to send your first email, configure an email inbox, and more for your OpenClaw agent using @resend.
Why OpenClaw needs an email API
OpenClaw is awesome. But the moment you want it to send an automated email, things get complicated fast.
The default approach is Gmail. Connect your Google account via OAuth, grant permissions, and let OpenClaw read and send from your inbox.
It works. But you're giving an AI agent broad access to your entire multi-year-old email account. Every message, every attachment, every draft.
That's a real problem. Security researchers have already shown how a single crafted email can trick an OpenClaw agent into leaking inbox data or deleting messages. Prompt injection through email content is not theoretical. It's happening.
Even if security wasn't a concern, Gmail has practical limits. Rate limits kick in when you try to send at any real volume. OAuth tokens expire and break your automation. And the setup itself takes longer than it should.
There's a simpler path. Instead of connecting a personal inbox, you give your agent a dedicated email API.
No inbox exposure. Just an API key and a verified domain.
That's where Resend comes in.
Setting up Resend
First, create a free account. No credit card is required. The free tier gives you 3,000 emails per month, which is plenty for getting started.
For this part, you will actually need a human in the loop in order to verify your email.
Once you're in, you have two options:
A) Provide the credentials to your OpenClaw agent
We recently disabled bot detection, so your OpenClaw agent can now access the Resend dashboard using a headless browser.
Needless to say, you should do this in a secure way using a password manager like 1Password, which has a built-in skill for OpenClaw.
