Frequently Asked Questions

With Topa.io, you can prevent specific phone numbers from ever receiving voicemails or SMS messages. The Blacklist (DNC) feature ensures that certain contacts—whether uploaded manually, added automatically, or returned through enrichment—are fully blocked from entering any campaign. This helps you stay compliant, avoid unwanted sends, and maintain clean outreach workflows.

Follow the steps below to understand how the blacklist works and how to manage it.

Blacklist (DNC)

Topa allows you to create multiple user logins, organize users into groups, and control what data and pages each user can access. This is commonly used by agencies and teams that want to separate data between clients, departments, or sales teams while providing a white-label experience.

Users can log in through either:

The standard Topa login domain

A white-label domain with no Topa branding

You can also upload your own logo so the dashboard appears fully branded for your organization or clients.
