Complaint Rate Target Calculator
Complaint thresholds are absolute, not relative to history. This tool gives you the per-send and per-month complaint allowance.
| MBP | Threshold | Max complaints/month |
|---|---|---|
| Gmail | 0.3% | 150 |
| Microsoft (Outlook, Hotmail, Live) | 0.1% | 50 |
| Yahoo / AOL | 0.2% | 100 |
| Apple iCloud | 0.2% | 100 |
Microsoft's 0.1% is the strictest. Plan to stay under that across all MBPs.

FAQ
What are the thresholds it uses?+
Gmail at 0.3 percent, Microsoft at 0.1 percent, and Yahoo, AOL, and Apple iCloud at roughly 0.2 percent. It multiplies your volume by each one to show the complaint count that trips it.
Should I enter my total send volume or the volume per provider?+
Per provider is more accurate, and this is the tool's main limitation. Each threshold is measured against the mail you send to that provider's users, so entering one total number gives you a rough allowance rather than an exact one.
Does it know my actual complaint count?+
No. It only turns your volume into a budget. The real numbers come from Postmaster Tools for Gmail, SNDS or JMRP for Microsoft, and your feedback loop reports elsewhere.
