MailMergic vs QRCertificates

MailMergic turns spreadsheet data into personalized certificates, transcripts, diplomas, and other documents that can be downloaded or emailed. For education workflows, users can upload PDF or Word templates and bring in student records from Excel, CSV, or Google Sheets. The service produces a separate PDF for each student and says it can process thousands of rows in one run. Before generation, its AI checks merge data for missing values, formatting problems, and mismatches. Users can email documents to spreadsheet recipients and monitor delivery, opens, and bounces in a dashboard. Student information systems can provide CSV or Excel exports without an API connection; Pro and Enterprise also list Zapier and a public REST API. The online service says it encrypts data in transit and at rest, hosts it in the EU, and uses access controls. Its free plan allows 25 documents per month for one user, with watermarks. Pro is $39 a year, billed yearly; Enterprise is $66 a year, billed yearly. An offline app is $107 a year, billed annually, for macOS and Windows.

QRCertificates is a web and API service for creating, delivering and verifying digital certificates and other credentials. Organizations can issue credentials individually or in CSV batches, using a drag-and-drop designer, reusable templates or uploaded artwork. Each credential includes a QR code and short code leading to a public verification page that needs no login or app. Credentials use Ed25519 signatures over canonical fields, and verification checks them against a fixed platform public key. Issuers can establish identity with evidence such as a verified email, DNS-confirmed domain or business registration, and can revoke credentials so public pages show that status. The API covers templates, issuance, batches, revocation, email delivery and public verification. Listed integrations include learning platforms, Zapier, Make and n8n. Plans include Free at free, Growth at $49 a month, Scale at $99 a month and Pro at $149 a month; Enterprise pricing is custom. The Free allowance is described as either 100 monthly credits or 30 certificates on different pages.
