## What is holding Resend · Email for developers back

1. **Developer and data sharing program**, 4 points lost. No developer portal or data sharing program was found on public pages. Fix: Document the program, the standard in use for example FDX in US banking, the supported partners and a sandbox.
2. **Passkeys at sign in**, 4 points lost. No passkey signal was found on the sign in page or in the published pages read. A prompt that starts only after a person types is not visible to the scan. Fix: Offer passkeys with conditional UI on the sign in page and for step up approvals.
3. **Documented delegate and data sharing controls**, 4 points lost. No public page on delegate access or connected app controls was found. Fix: Publish a help page on delegate access and add a connected apps screen where customers revoke access.
4. **Browser tools exposed to agents**, 3 points lost. The sign in and home pages register no browser tools for agents. Fix: Register tools for safe tasks such as location search and price lookup with navigator.modelContext.
