Complaint Rate Target Calculator
Complaint thresholds are absolute, not relative to history. This tool gives you the per-send and per-month complaint allowance.
| Provider | Published figure | Complaints a month |
|---|---|---|
| Gmailtarget: keep spam rates below 0.10% | 0.1% | 50 |
| Gmaillimit: avoid ever reaching 0.30% | 0.3% | 150 |
| Yahookeep your spam rate below 0.3% | 0.3% | 150 |
| Microsoft (Outlook.com)not a requirement: its SNDS FAQ calls under 0.3% a good bar to shoot for | 0.3% | 150 |
| Apple iCloudpublishes no complaint number and offers no feedback loop | None published | n/a |
Plan for Google's 0.1%. It's the lowest number any provider publishes, and Google reports your rate in Postmaster Tools.
You ran the numbers. Now see your real ones.
A calculator works from the figures you type in. Outsolvi measures them on the email you actually send, and grades every open so Apple Mail pre-fetches and security scanners don't inflate the count. Outlook and Gmail, from $7/user/mo billed yearly, 14-day free trial.
See it on your own inboxShows how many spam complaints your monthly volume allows under each mailbox provider's published figure, and which providers publish none. Gmail has a 0.1% target and a 0.3% limit, Yahoo asks for below 0.3%, Microsoft gives 0.3% as a reference, and Apple publishes nothing.

FAQ
What are the thresholds it uses?+
The ones providers publish. Google asks senders to keep spam rates below 0.1 percent and never reach 0.3 percent. Yahoo asks for below 0.3 percent. Microsoft has no requirement, but its SNDS FAQ calls under 0.3 percent a good bar to shoot for. Apple publishes no complaint number and offers no feedback loop.
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.

Nate built Outsolvi after watching every email-tracking tool he had ever used lie to him about opens. Outsolvi grades every open as a person or a machine, in Outlook and Gmail, so the number on the dashboard is one a rep can actually act on.
