Blocked Sources and Scrub Services for Lead Filtering

Reject leads from unwanted vendors and scrub incoming leads against the Blacklist Alliance and DNC.com suppression lists before they enter a playbook.

Mav gives you two tools for keeping bad leads out of your playbooks: Blocked Sources and Scrub Services. Blocked Sources lets you permanently reject leads from specific vendors or sub-sources. Scrub Services connects Mav to external suppression databases so every incoming lead is checked against the Blacklist Alliance and DNC.com lists automatically—before it enters a playbook.

Both tools live under Settings → Filters.

Blocked Sources

Use Blocked Sources to prevent a specific lead source—or a combination of source and sub-source—from submitting leads to your account. Once a source is blocked, any lead that arrives carrying that source identifier is rejected automatically.

1. Open Filters

   Navigate to Settings → Filters.

2. Open Blocked Sources

   Click Blocked Sources.

3. Enter the source details

   Enter the Source name. If the source uses sub-sources, enter the Sub-Source value as well—leaving the sub-source blank blocks all leads from that source regardless of sub-source.

4. Save

   Click Save. The block takes effect immediately for any new incoming leads.

If a vendor uses multiple sub-sources, you can add separate blocked source entries for each one, or block the parent source entirely by leaving the sub-source field empty.

Scrub Services

Scrub Services connects Mav to external suppression databases. When enabled, Mav checks every incoming lead against the selected list before it enters a playbook—leads that match a suppression record are rejected automatically.

Mav currently supports two scrubbing databases:

Service	What it screens for
Blacklist Alliance	Known litigants and serial TCPA complainants
DNC.com	Do-Not-Call registry records

1. Open Filters

   Navigate to Settings → Filters.

2. Open Scrub Services

   Click Scrub Services.

3. Enable a scrubbing database

   Toggle on Blacklist Alliance, DNC.com, or both.

4. Enter your API key

   When prompted, enter the API key for each service you’ve enabled. You obtain these keys directly from Blacklist Alliance and DNC.com.

5. Save

   Click Save. Mav begins scrubbing all incoming leads against the enabled databases immediately.

Scrub Services requires a valid API key from each third-party provider. Make sure your API key is active and has sufficient query credits—if the key is invalid or exhausted, scrubbing will fail and leads may pass through unchecked.
