MailMyCertificate
MailMyCertificate turns participant data and a certificate design into personalized PDF certificates.
What MailMyCertificate is
MailMyCertificate turns participant data and a certificate design into personalized PDF certificates. Import recipients from a CSV file or public Google Sheets URL, then place participant fields on a PNG or JPG template in the visual editor; PDF templates are not supported. The browser generates certificates in batches, and finished files can be downloaded together as a ZIP or sent individually through Gmail. Google OAuth is used for delivery, with the `gmail.send` permission; the app says it cannot access the inbox or contacts. Certificate generation, participant data, and generated PDFs stay locally on the device. During sending, the backend temporarily receives recipient details, message content, and the PDF attachment, and says it does not intentionally retain them afterward. The service is free, has unlimited certificates, requires no signup, and has no paid tiers. The editor works best on desktop, while mobile is suited to downloading after setup. The guide recommends about 400 emails per batch, subject to Gmail API limits and browser performance.
