What Supermail is
Supermail is the email infrastructure layer powering Superfolio. It is not a consumer email service or standalone product. Supermail processes inbound email to application alias addresses for the sole purpose of updating job application records inside Superfolio.
What data Supermail processes
When a recruiter or hiring platform sends an email to a Supermail alias, Supermail processes: the sender's email address and display name, the email subject line and body content, the timestamp of receipt, and inferred signal classification (e.g. interview request, rejection). Signal classifications are generated automatically and may be incomplete, inaccurate, or incorrect. Users should independently verify all information. Email content is stored to power the in-app email timeline and is retained as described in the Data Retention section below.
How data is used
Processed data is used exclusively to update the corresponding job application record inside Superfolio and to forward the email to your registered account email address. Inferred signals (e.g. interview invite, rejection) may be used in aggregate and anonymised form to power platform-wide insights such as company response patterns. No data is used for advertising, third-party analytics, or model training.
Data sharing
Supermail does not sell, rent, or share your data with third parties. Email data processed through Supermail aliases is not accessible to other users or external systems. Data is shared with infrastructure providers necessary to operate the service: Postmark (inbound email reception), Resend (email forwarding), and Supabase (database hosting), each operating under appropriate data processing agreements.
Data retention
Email data associated with a job application is retained for as long as your Superfolio account is active. You can delete individual application records or your entire account at any time. Deletion requests are processed within 30 days. Certain records may be retained where required for legal, security, fraud prevention, or compliance purposes.
Security
All data is encrypted in transit (TLS) and at rest. Access to production data is restricted and logged. For a detailed description of our security practices, see the Security page.
Your rights
You have the right to access, correct, or delete your data at any time through your Superfolio account settings. For requests that cannot be completed in-product, contact us directly.
