B2B Cold Email Deliverability Penalty.

Simulate the logarithmic decay of your domain reputation and inbox placement rates when exceeding bounce thresholds in B2B cold outreach campaigns.

## The 2024 Deliverability Apocalypse

Google and Yahoo introduced strict new requirements for bulk senders. If your domain's spam complaint rate hits 0.3%, or your hard bounce rate exceeds 2% consistently, your sender IP and domain reputation will be blacklisted across the Google Workspace ecosystem.

### FAQ

**Q: What is a hard bounce versus a soft bounce?**
A: A hard bounce means the email address literally does not exist (the domain is dead, or the employee left the company). A soft bounce means the inbox is temporarily full or the receiving server is down. Hard bounces are severely penalized because they indicate you bought an unverified, scraped contact list.
