Most cold emailers obsess over subject lines and copy. But if your bounce rate is above 5%, none of that matters.

Here's what actually kills campaigns:

1. Role-based addresses (info@, support@, admin@)

These rarely reach a real person. High bounce risk, low reply rate. Filter them out.

2. Catch-all domains

They accept every email — even fake ones. You think you got a valid address. Your ESP disagrees.

3. Stale lists

B2B email addresses decay at 30% per year. That list from 6 months ago? A third of it is dead.

4. Disposable emails

Temp-mail signups inflate your list and inflate your bounce rate. Dead weight.

The fix isn't a better sequence. It's cleaning your list BEFORE you launch.

Validate syntax → verify domain → confirm mailbox existence. Every time.

That's what BounceGuard does. 🛡️
