Beehiiv New Subscriber Agent with Hermes
The sharpest instruction in this template concerns what stays empty. Seniority, team size and why somebody subscribed are not on the record, so those fields are left blank rather than inferred from an email domain. Hermes reasons capably across ordinary problems, and the discipline being asked for is to hold that back.
Watch it work before it's live
Run a staged conversation — no account needed. The agent handles it for real while a simulated world answers its tool calls; nothing touches real accounts, and nothing is actually sent.
New subscriber
Free tier. utm_source=partner-swap, utm_campaign=aug-crosspost, referring site theampereletter.com. Signed up 07:41 CEST on mobile and confirmed the double opt in four minutes later. Her email domain matches a company already listed on the sponsor prospect sheet.

Tagging rules
Which tags go on a signup and where each one comes from, the custom fields worth filling from the subscription record, and what makes a subscriber notable enough to interrupt someone for, usually a company domain you sell to or anyone on a paid plan.

Why Hermes for this agent
Blank is a valid answer
A field that cannot be filled from the record stays unfilled. That instruction is easy to write and is the one every capable model wants to break.
Segments checked before pinging
If a tag drops a notable subscriber into an automated sequence, the Slack line says so. Knowing the second-order effect of your own write is a small piece of care worth having.
Before you fork
How do we check it is not guessing at the fields?
Annual Premium Upgrade is the useful staged signup, because it arrives from organic search with no UTM values and no referrer beyond google.com. A correct run tags the tier and the paid plan, tags the source as organic, and leaves the referrer tag off entirely. Any run producing a confident referrer from that record is inventing, and you have found it before a segment was built on it.
