📋Step-by-Step Instructions in Dashboard

01

How the Platform Global Suppression List Operates

👉 Where to Click:Contacts > Suppression & Blacklist

MailerWeb maintains a collective intelligence system called Global Suppression List (GSL). Whenever a number is flagged as an operator trap, hard bounce, invalid WhatsApp account or suspended number, it is logged globally. Before dispatch, campaigns cross-check the GSL in microseconds to suppress dead deliveries, saving credits and protecting chip quality.

02

Configure Automated Opt-Out Triggers

👉 Where to Click:Settings > Compliance & Opt-Out

To comply with Meta policies and privacy regulations, campaigns can include 'Reply STOP to unsubscribe'. MailerWeb chat processors listen for keywords like 'STOP', 'CANCEL', 'UNSUBSCRIBE', 'SAIR' or 'BAJA'. Upon detection, the contact is placed in the WhatsApp blacklist, preventing future campaign dispatches.

03

Audit and Manually Manage Blacklists

👉 Where to Click:Contacts > 'Suppression / Blacklist' Tab > '+ Add Suppression'

If a customer requests opt-out via call or support ticket, add them manually by entering their phone or email and specifying channels (WhatsApp, SMS, Email or All). View block date, reason log and revoke suppression with one click if authorized.

🚨Critical Safety Rules & Ban Protection

  • 🛡️Respect Unsubscribes Instantly: Pushing messages to users who requested to stop triggers direct user reports in WhatsApp. As few as 3-5 reports within one hour can trigger an account ban.
  • 🛡️Channel Isolation: An opt-out on WhatsApp does not necessarily void an email relationship if the lead only objected to instant messaging. MailerWeb segregates channel blacklists cleanly.

❓Frequently Asked Questions & Troubleshooting

P:If I upload a spreadsheet with blacklisted numbers, will they receive messages?

No! Platform precedence guarantees that suppression overrides imports. Any matching blacklisted entry is skipped automatically during campaign dispatch.

P:How can a contact opt back in?

The customer can send 'START' or 'YES' in WhatsApp, or an administrator can remove the suppression entry from the Contacts module upon verified consent.
