Managing audience list compliance is critical for automated communication systems. The Block Manager panel (Access Control) provides a local blacklist mechanism inside your WordPress site, allowing you to suppress automated outbound transactional and marketing traffic to specific recipients instantly.

By adding phone numbers or email addresses to your blocklist, Wawp intercepts outgoing payloads before they leave your server, protecting your API balances and respecting user opt-out choices.

Complete Account and Access Ban When you block a user's phone number or email address, Wawp automatically propagates the block to all associated credentials for that account. Specifically:

Phone Block: Blocking a phone number will automatically restrict the associated account and its linked email address.
Email Block: Blocking an email address will automatically restrict the associated account and its linked phone number.

This restriction goes beyond suppressing outbound message or email delivery; it completely blocks the user from interacting with the website (including logging in, performing OTP checks, registering, or placing orders).

2. Blocked Email Addresses Tab

This tab manages email addresses restricted from receiving automated newsletters, order transactional updates, or SMTP-routed email alerts.

Blocked Email Addresses Tab overview — **Blocked Emails Panel**
Blacklist individual email addresses from receiving newsletters, transaction updates, or alerts.

Frontend Format Validation

Wawp validates the input format using a strict client-side regular expression before adding it to the list:

/^[^\s@]+@[^\s@]+\.[^\s@]+$/

If the entry does not match standard email syntax (e.g. missing @ or domain suffix), Wawp blocks the addition and prompts a toast error.

Restricted Email Controls

Restricted Emails Counter: Displays a numerical badge showing the total number of blocked email addresses.
Email Grid Layout: Renders each blocked address as a clean, hover-interactive white card featuring a mail icon.
Clear All Option: Instantly purges the entire email blacklist database.
Unblocking Emails: Click the hover-triggered X delete button on any email card to lift the routing ban.

All blocked email addresses are compiled and stored as a newline-separated string in your WordPress database under the option key: wawp_block_email_list.

3. Automated Keyword Opt-Outs (Wawp.net Cloud Suppression)

If you want to configure automated keyword suppression policies (e.g., automatically blocking users who message you "STOP" or re-subscribing users who message you "START"), these behaviors are governed by Wawp's central cloud suppression engine.
