MailAuth Inspector runs inside the user’s browser and interacts with Gmail to identify the relevant message card, fetch the related “Show original” content, and extract SPF, DKIM, and DMARC results for display in the Gmail interface.
The extension stores user configuration in browser storage. Configuration may include dashboard preferences, rule toggles, theme choices, Google Sheets destination details, and settings related to billing mode or product access.
Optional workflows can store queue items, duplicate-prevention data, usage information, billing status, and a stable account identifier in browser storage. Queue items may include contact or message-related workflow data, score and priority information, retry status, and error details.
If the user enables Google Sheets integration, MailAuth Inspector can append rows to a sheet selected by the user. Those rows can include sender email, sender domain, Gmail thread and message identifiers, auth results, alignment and policy values, spoof-risk details, and workflow status fields.
If the user accesses paid features, MailAuth Inspector can communicate with billing and subscription services through secure online checkout pages. The extension stores billing status and access information locally. Full payment card details are handled by the payment provider, not by the extension itself.
Queue and dedupe data are managed inside the extension and are intended to be limited rather than unbounded. Privacy-related controls in the extension can clear local workflow state, and retention-related settings can be adjusted from the dashboard where available.
