Switching to Nucleus was a game-changer. Within 24 hours, we saw a 35% jump in email deliverability and doubled our open rates. Our audience targeting became dramatically sharper — and our campaigns started converting faster. The difference was immediate and measurable.
Yahoo Sender Hub (senders.yahooinc.com), same core metrics, same 0.3% complaint threshold.
Microsoft SNDS covers Outlook, Hotmail, and Live. Note: consumer accounts only, not Microsoft 365 or Exchange Online.
Validity Sender Score (senderscore.org), a third-party 0-100 score. Above 80 is good, below 50 is real trouble.
The quick read on your numbers:
Complaint rate: under 0.1% golden, 0.1-0.3% watch it, over 0.3% fix it today.
Bounce rate: under 2% fine, 2-5% clean house, over 5% is a real list problem.
Domain reputation: High is great, Medium is a warning, Low or Bad means you're already filtered.
If your numbers came back rough, recovery follows real ranges: minor damage clears in 2-4 weeks of clean sending, moderate damage takes 4-8 weeks, and severe damage (multiple blocklists, a "Bad" Postmaster rating) runs 8-16+ weeks. Some domains never fully recover. The clock only starts once clean behavior replaces the bad pattern, and resuming full volume too early is the most common way senders reset their own clock back to zero.
The Cliff Notes
Authentication proves who you are. Reputation proves you're trustworthy, and it's judged continuously, not once.
83% of delivery failures trace back to reputation, not content, and most senders never check it.
Domain reputation is portable. You can't escape a bad one by switching tools.
Spam traps are hidden mines. Pristine traps blocklist you instantly; recycled and typo traps erode you slowly.
Recovery is slow: 2-4 weeks for minor damage, 8-16+ for severe. Check your dashboards weekly.
