BEFORE YOU START
A few useful answers.
Does Stampwyn host or send my email?
No. Stampwyn analyzes authentication and transport reports. Your existing mail hosting and delivery services stay in place.
Will reports appear immediately?
Reports depend on receiving providers and their schedules. DNS changes do not create historical data, and not every receiver sends reports.
Can an agency manage our domains?
Yes. An owner can invite a partner and grant permissions for the relevant domains. Delegated access can be revoked.
Can I register today?
Stampwyn is currently in a private pilot. Existing invited users can sign in; public registration and billing are not available yet.
