Frequently asked questions
How do I run my first inbox placement test?
Create a project, add your sending domain, and trigger a test from the dashboard or via the API. See quickstart.
Why is my DKIM showing as weak?
Ensure you use 2048-bit keys and rotate keys periodically. Our report links to recommended DNS values.
How are tests counted for billing?
Each seed-list send counts as one test. Overage rates apply after your monthly quota.
Do you support custom seed lists?
Yes — upload a CSV in the dashboard or contact sales for managed lists.
Why am I landing in Promotions on Gmail?
Subject and template patterns can trigger Promotions. Test variants and review our content heuristics guide in the docs.
