Automated compliance
Hoop includes built-in compliance features to automatically manage DND based on contact responses.SMS compliance
Opt-out messages
An automatic opt-out message is appended to SMS communications, allowing recipients to reply STOP to unsubscribe. This automatically updates the contact’s SMS DND settings.
Email compliance
An unsubscribe link is automatically included in outgoing emails. When clicked, it sets the contact’s email DND. Customize the unsubscribe settings at Settings → Business Profile → General section.
SMS DND types
Two types of SMS DND can be applied to a contact:| Type | How it’s set | How it’s removed |
|---|---|---|
| Temporary | Contact’s number returns error codes 30003, 30005, or 30006 | Can be updated from the contact record |
| Permanent | Contact replies STOP, UNSUBSCRIBE, or CANCEL — or returns error code 30004 | Contact must text START to the number to re-opt in |
DND for inbound calls and SMS
Enable DND Inbound to prevent a specific contact from being able to call or text your CRM number. This blocks all incoming communication from that contact.
Email DND auto-enable triggers
The system will automatically enable email DND for a contact if any of the following occur:- ISP permanent failures — bounce, generic, suppress-complaint, suppress-unsubscribe, or suppress-bounce events.
- Spam complaint — the recipient marks your email as spam (Mailgun complaint event).
- Unsubscribe — the recipient clicks the unsubscribe link.
You can disable DND from the contact record for the reasons above, except when the contact has been marked as SPAM. For bounce or suppression events, remove the contact’s email from your ISP’s suppression list and validate the email before re-enabling.
Workflow integration
You can trigger DND changes automatically in workflows. For example: when a contact unsubscribes from email, a workflow action automatically enables their email DND — ensuring every touchpoint respects their preferences without manual intervention.FAQs
