MarketingRecorded example

Watch your competitors' email offers

Get a private email address per competitor, sign up to their newsletters, and get a brief of every welcome offer, hook, call to action and discount link they send.

poppi · 2026-10-08 18:49 UTC · "ohhh we’ve got your new fave soda right here 😋" · hook "welcome to the future of flavor!" · no offer in the text Zevia · 18:54 UTC · "Welcome to the Sip Squad 🥤" · CTA Shop Now (after a confirm-your-subscription email) Recess · 18:55 UTC · "get calm cool collected with Recess" · shop link carries discount=TEAMRECESS Gap to exploit: none of the three pairs a clear value prop with an explicit offer in the welcome email.

Build it step by step

Create one address per competitor

Each address only receives mail and comes with an access token. Keep both.

agentmail.create-address ↗

{
  "tool": "agentmail.create-address",
  "input": {
    "label": "poppi"
  }
}

Sign up to their newsletters

Use each address in the competitor's footer or pop-up signup form. Open any confirm-your-subscription link.

Read what arrived

List messages per address, then read each one: subject, sender, text (HTML emails included), links and codes.

agentmail.get-message ↗

{
  "tool": "agentmail.get-message",
  "input": {
    "address": "superpowers-agents+poppi-…@agentmail.to",
    "access_token": "…",
    "message_id": "…"
  }
}

Write the brief

Summarize offers, hooks, calls to action and links from the email text only, then patterns worth copying and gaps to exploit.

Before you build

Can these addresses send email?

No. They only receive mail, so they can't be used for outreach or spam.

Why is there no offer for some brands?

Many brands put the offer in an image. The brief says so instead of guessing, and discount codes often show up in links.

How long until emails arrive?

Welcome emails usually arrive within minutes of signing up; campaigns follow over days and weeks.
