Do Not Disturb (DND) lets you prevent outgoing messages on specific channels for a contact — or block all communication entirely. It is essential for respecting contact preferences and maintaining compliance with SMS and email regulations.
DND settings

DND types

Prevents any communication from being sent to the contact through any integrated channel.
Restrict one or more specific channels while keeping others open. Configurable for: Calls, Email, Facebook, GMB, SMS, and WhatsApp.
For example, if a contact prefers email over text, you can enable SMS DND while leaving email open.

DND statuses

DND status
StatusMeaning
DND OnNo automatic or manual outgoing messages are sent on that channel
DND OffMessages function normally — automated and manual
If a channel integration is disconnected and later reconnected, each contact retains its previous DND status.

Automated compliance

Hoop includes built-in compliance features to automatically manage DND based on contact responses.

SMS compliance

1

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.
2

Sender information

SMS messages can be configured to include sender details for transparency.
3

Customize

Go to Settings → Phone System → Messaging → Messaging Compliance to customize opt-out message wording.

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.
Email DND

SMS DND types

Two types of SMS DND can be applied to a contact:
TypeHow it’s setHow it’s removed
TemporaryContact’s number returns error codes 30003, 30005, or 30006Can be updated from the contact record
PermanentContact replies STOP, UNSUBSCRIBE, or CANCEL — or returns error code 30004Contact 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.
Inbound DND

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
