FAQPage Schema
How do I manage email and domain suppression lists for cold outreach?

You can add, remove, and list individual or bulk email addresses and domains to your suppression lists. This protects your sender reputation and ensures compliance during cold outreach by preventing contact with blacklisted targets.

What is the best way to bulk blacklist domains before a cold outreach campaign?

The best way to bulk blacklist domains is by adding bulk lists of specific domains like 'gmail.com' to your suppression list before launching a campaign. This automatically blocks all associated emails to focus your outreach on B2B targets.

Can I add individual email addresses to a blacklist or do I need to upload a bulk list?

You can add individual email addresses directly to your blacklist instead of uploading a bulk list. The suppression list management supports both individual and bulk additions, giving you flexibility for specific blocks or mass pre-campaign setup.

How does domain blacklisting work for maintaining sender reputation?

Domain blacklisting maintains sender reputation by suppressing all emails from specified domains, ensuring you never contact them during outreach. This prevents complaints and bounces from known problematic domains, keeping your sender account healthy.

How do I clean up stale entries on an email suppression list?

Cleaning up stale suppression list entries requires removing outdated individual or bulk email addresses and domains. You can manage this cleanup process to ensure your compliance lists remain accurate and do not unnecessarily block valid outreach targets.
