Managing blocked and unsubscribed contacts is essential for maintaining high deliverability, protecting your WhatsApp quality rating, and staying compliant with privacy regulations. DMLY provides structured tools to handle both blocking and unsubscribing efficiently.
Blocking vs Unsubscribing — What’s the Difference?
BlockingBlocking typically occurs when:
A user blocks your WhatsApp number directly
A platform restriction prevents delivery
Messages become undeliverable repeatedly
Blocked contacts cannot receive messages from your number.
UnsubscribingUnsubscribing happens when:
A user opts out of marketing
They reply with keywords like STOP
You manually mark them as unsubscribed
Unsubscribed contacts:
Can still message you
Will not receive marketing broadcasts
Should be excluded from promotional campaigns
Managing Unsubscribes in DMLY
Automatic Unsubscribe (Recommended)DMLY supports automated opt-out handling.
When a contact sends:
STOP
Stop

You can configure automation to:
Apply the Unsubscribe tag
Remove them from marketing segments
Prevent future promotional broadcasts
This ensures immediate compliance.
Manual UnsubscribeTo manually unsubscribe a contact:
Go to Contacts
Click the More Actions (⋮) menu
Select Edit Contact
Add the tag: Unsubscribe
Save
The contact will now be excluded from marketing segments.
Excluding Unsubscribed Contacts from BroadcastsWhen creating a marketing segment:
