Gmail does not natively offer a 'resend' feature for sent emails. Users who want to send the same email again to the same or different recipients must manually copy all fields. This extension automates that by cloning the original sent email into a new compose window.

User opens a sent email in Gmail → Extension injects a Re-send button in the toolbar → User clicks the button → Extension reads the original email's To/Cc/Bcc fields, subject, and body → A new compose window opens pre-filled with the original content → User can modify recipients or content before sending

Target users: Google Workspace / Gmail users who frequently need to resend emails to the same recipients / Office workers and administrators using Google Workspace (Sateraito Office ecosystem)

The main JS file (resend_btn.js) is minified, making full logic tracing difficult, but key behaviors (button injection, DOM manipulation for compose window) are clearly identifiable
The extension name references 'Sateraito Office' and the website (sateraito.jp) may offer related paid SaaS products, but the extension itself contains no payment or account integration

Monetization

No paid features detected

No payment APIs, subscription checks, feature gates, upgrade prompts, or premium/Pro tiers detected in any source file. The 'pro' keyword hits from the static scan are false positives from minified JavaScript variable names (e.g., 'Object.prototype'), not payment-related code. The extension has no background service worker that could check license status.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is a pure content script that injects a Re-send button into Gmail's interface. It operates entirely client-side on the already-open Gmail page. There are no authentication flows, no API calls requiring credentials, no account creation, and no communication with external services for auth purposes. Users need to be logged into Gmail (as it operates on mail.google.com), but that is Google's own service login, not something the extension requires or controls.
