Resend Robot Send

Send Dev Email (Simulate Inbound)

You are running the /resend-robot-send workflow. Use Resend Robot to simulate receiving an inbound email through the app's webhook pipeline.

Commands

Reply to most recent outbound email

bin/rails "resend_robot:reply[0,Thanks for the email!]"

This finds the most recent outbound email, uses its recipient as from and its reply-to address as to, then:

1. Stores the inbound email JSON
2. POSTs to the webhook endpoint (default: /webhooks/resend)
3. The app's webhook controller processes it through the normal pipeline

The first argument is the index (0 = most recent, 1 = second most recent, etc.).

Reply to a specific outbound email

First find the email index:

bin/rails resend_robot:outbox

Then reply to it:

bin/rails "resend_robot:reply[2,I have a question about this]"

Send from a specific address

bin/rails "resend_robot:receive[stranger@gmail.com,,Question about something,Is this available?]"

Arguments: [from, to, subject, body]

• If to is empty and reply_domain is configured, Resend Robot auto-generates a cold-{hex}@{reply_domain} address
• The to address should match your app's inbound email domain for the webhook controller to accept it

Common Patterns

• Reply to last email: resend_robot:reply[0,Thanks! Got it.]
• Cold inbound: resend_robot:receive[stranger@gmail.com,,Question,Is this available?]
• Test full cycle: Send email via app -> /resend-robot-read to verify -> /resend-robot-send to reply -> check app state

Important

• The dev server must be running (bin/dev) for inbound simulation to work
• All inbound emails go through the REAL app webhook pipeline (same code path as prod)
• If your app processes inbound emails asynchronously, poll for completion after sending
