When something changes, the right thing happens.
Your agent runs the conversation. Rules keep the record behind it — tag a new contact, set a field, start a sequence, or notify you the moment a tag, field, or date changes. Set the rule once; it fires once per contact, and never spams.
Your agent talks. Rules keep the record.
Your agent handles the conversation — reading what a customer means, answering from your catalog, closing the sale. You would never script that. Rules handle the other half: the housekeeping every one of those conversations leaves behind. A contact gets tagged, a field changes, a renewal date comes due — and the right follow-up should just happen. That is not a conversation to design. It is a rule to set. The agent is smart on purpose; rules are exact on purpose.

The old way: tag it by hand, or bury it in a flowchart.
Without rules, the housekeeping falls on you. You tag contacts by hand, try to remember which lead needs a follow-up, and export a spreadsheet to find whose trial ends this week. Or you wire it into a flow builder — where this logic gets tangled into the same canvas that runs your messaging, and one burst of updates can fire the same action over and over.
- ✕You tag and update contacts by hand — or forget, and your segments rot.
- ✕The follow-up that should fire on a status change waits until you remember it.
- ✕Finding whose renewal is due this week means exporting a spreadsheet and eyeballing dates.
- ✕In a flow builder, with no throttle, ten quick edits fire the same action ten times.

When an event happens, do these actions.
A rule is one sentence: when this happens to a contact, do these things. Pick the event you are watching for, list what should happen, and HyperDM runs it on every matching contact — in order, the moment it fires. There is no canvas to maintain and nothing to check by hand.
Pick the trigger
a new contact, a tag, a field, or a date.
List the actions
tag, set a field, start a sequence, notify you. They run in order.
It runs itself
every matching contact gets the actions, once each, automatically.
Five triggers. Everything that happens to a contact.
Rules listen for the events that already happen as your agent works — nothing extra to wire up. Narrow a rule to one specific tag or field, or fire on any.
New contact
someone messages you for the first time. Tag them by source and start a welcome sequence.
Tag added
a tag lands on a contact, like vip or abandoned-cart. Subscribe them to the sequence that should follow.
Tag removed
a tag comes off a contact. Pull them out of the sequence it was keeping them in.
Field changed
a custom field's value changes. Re-segment, sync a status, or notify you.
Date field
a date you store on the contact, like a renewal or a birthday. Fire on the day, or a set number of days before or after — checked once a day.
Then it does the work — in order, automatically.
Stack as many actions as a rule needs; they run top to bottom every time it fires. The vocabulary is the same one your sequences use, so nothing is a special case.
Add a tag
create it if it is new, then tag the contact. Segment as things happen.
Remove a tag
take a tag off to move a contact out of a segment.
Set a field
write a value to any custom field, like status = churned.
Subscribe to a sequence
drop the contact into a live nurture or follow-up by name.
Unsubscribe from a sequence
pull them out the moment they should not get more.
Notify you
HyperDM leaves a note on the contact's thread in your shared inbox, so a human sees it. Not an email or a text; a note where the conversation already lives.
Start a flow
if you've built a flow, a rule can trigger it. A power-user option, not the point.
Guardrails so it never spams a contact.
Automation that fires twice is worse than none — it messages a customer again, tags them again, and erodes the trust your agent just built. HyperDM ships the guards that keep a rule exact, so your lists stay clean and no one hears from you twice.
The honest FAQ.
Set the rule once. Get the hour back.
Every conversation your agent closes leaves a trail worth acting on — a tag, a field, a lead to follow up. Rules turn that trail into the next action instead of a note you'll get to later. Live in under 10 minutes, free for your first 50 conversations a month, no credit card.
