Gmail email mis-send prevention tool that adds a confirmation dialog before sending emails

Prevents accidental email mis-sends in Gmail by requiring users to manually verify From, To, Cc, Bcc, Subject, and Attachments through a confirmation dialog with checkboxes before the email is actually sent

1. User composes an email in Gmail. 2. The extension replaces the 'Send' button with a 'Confirm' button. 3. User clicks 'Confirm'. 4. A modal dialog displays From, To, Cc, Bcc, Subject, and Attachments with individual checkboxes. 5. Addresses with mismatched domains are highlighted in red. 6. User must check all boxes to enable the OK button. 7. After clicking OK, the Confirm button changes back to Send. 8. User clicks Send to actually send the email.

Target users: Business professionals who send emails via Gmail / Users concerned about sending emails to wrong recipients / Organizations using Gmail/Google Workspace

Extension is a single content script (checker.js) with no background scripts, making analysis straightforward
The donation link points to external site gmsck.seya.work but the actual donation mechanism is not visible in the extension code itself
No API calls or external service integration detected beyond the donation link

Monetization

No paid features detected

The extension is completely free with no feature gating. It includes a voluntary donation link (https://gmsck.seya.work/#donate) shown in the confirmation dialog, but no paid features, subscription tiers, or payment-gated functionality exist. The 'pro' keyword hit in verified_contents.json is a false positive (appears in a block_size/hash context).

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is a content script that runs directly on Gmail pages. It does not implement any login UI, authentication flow, or account creation. While users must be logged into Google/Gmail to use the extension, that is a requirement of the destination service, not the extension itself. The extension has no background scripts, no storage permissions, and no external API calls that would require authentication.
