MailConsent

MailConsent is a web app + API that creates verifiable, audit-ready proof of email consent and preference changes. Instead of storing messy screenshots and scattered logs, it issues a tamper-evident “consent receipt” for every signup, double opt-in confirmation, unsubscribe, and preference update. Each receipt includes hashed metadata (timestamp, source form/app, IP region, user agent, consent text version, and list/purpose) and can be exported as a signed PDF or retrieved via API for internal audits, ESP disputes, or regulatory inquiries. It also provides a lightweight SDK for web forms and server-side events, plus a dashboard to search by email, event, or campaign. This is not an ESP; it plugs into existing stacks (SendGrid/Mailgun/SES, HubSpot, Shopify) and focuses narrowly on compliance evidence and operational clarity.
