MailMyCertificate review
A privacy-focused certificate generator for local batch PDF creation and Gmail delivery.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MailMyCertificate is a browser-based certificate automation tool for hackathon organizers, educators, workshop hosts, and event teams. It supports PNG and JPG certificate templates, participant imports from CSV files or public Google Sheets URLs, visual drag-and-drop field placement, personalized PDF generation, ZIP downloads, and optional Gmail delivery through OAuth. Its open-source, MIT-licensed model and local browser processing make it suited to teams that want a free workflow with participant data stored on their own device during certificate generation.
The workflow is focused and practical: upload a template, place fields visually, import participant data, generate certificates in bulk, and download the results as a ZIP archive. The published capabilities also support Gmail delivery, while IndexedDB storage enables local browser processing. CSV imports are documented for up to 400 rows, so the tool fits many workshops, events, and educational batches but should be assessed against larger recipient lists. Public Google Sheets imports add another route for preparing participant data without requiring a separate spreadsheet export.
MailMyCertificate stands out for its open-source and self-hosted options, no-signup Free plan, no payment requirement, and no certificate cap stated for the plan. The tradeoff is a narrower ecosystem centered on Gmail and Google Sheets, with PDF as the export format and no AI features. Choose it if local processing, source availability, and straightforward batch certificates matter more than a broad credentialing platform. Teams needing a wider integration set or workflows beyond its browser-based certificate generation should consider an alternative.
