Folderly complaint budget
Calculate how many spam complaints a campaign can survive.
Enter planned volume, Gmail share, and expected complaints to see whether the campaign has room to scale or needs a tighter audience and safer message first.
Complaint budget
See how few complaints a send can afford.
Estimated Gmail recipients: 3,000. Other recipients: 2,000.
Modeled Gmail spam rate
0.10%
This is planning math, not live Postmaster Tools data. Actual reported spam rate can differ by sender, mailbox mix, filtering, and reporting lag.
Share the planning card with the owner of the list before volume increases.
3
complaints at a 0.1% planning ceiling
9
complaints around a 0.3% danger band
6
more complaints before danger band
Use this before scaling a list.
If one or two complaints can move the campaign into a watch band, narrow the audience, improve the opening line, add a clear opt-out, and test the draft before increasing volume.
Small lists can have tiny complaint budgets.
A campaign with a heavy Gmail audience may have only a handful of complaints before the risk profile changes. Use this calculator as a pre-send constraint, not as a delivery guarantee.
Pair complaint math with message review.
Complaint risk is usually a relevance problem before it is a math problem. Run the draft through the Folderly checker to review copy, AI-template smell, opt-out language, and sender setup.
Is this live Postmaster Tools data?
No. It is a planning calculator. Live spam-rate reporting depends on mailbox provider data, sender reputation, reporting volume, and delay.
Why does the calculator focus on Gmail share?
Gmail and Googlemail recipients often make up a large share of cold outreach lists, and public sender guidance includes spam-rate thresholds that are useful for planning.
What should I do if the budget is tiny?
Reduce volume, tighten audience fit, rewrite the opener, make the opt-out clear, and run the draft through the Folderly deliverability checker before scaling.
