Introduction

Organisations often need to issue many digital certificates at once – for a course, webinar, or training program – without hand-emailing each one. Certopus makes bulk certificate delivery easy.

In Certopus, you can design a certificate template, upload a list of recipients (name and email), and then in “a few clicks” all personalized PDFs are generated and sent out. The platform handles the email merge automatically, attaching each recipient’s certificate or providing a secure link to download it .

This means even 100 or 1,000 certificates can go out in the same time it takes to send just 5. Below are three practical methods to send bulk certificates via email with Certopus:

1. Use Certopus’s Built-In Bulk Email Feature

This is the simplest way: Certopus itself can issue and email all certificates at once. After logging in, use the drag-and-drop designer or a template to create your certificate. Then prepare a spreadsheet (CSV or Google Sheet) with each recipient’s name and email.

In Certopus, select “Bulk Issue” or “Deliver”, upload the list, and click to send. Certopus will merge each row into a unique certificate and email it automatically. You can choose to attach the PDF or send a link. For example, Certopus can send each attendee’s certificate as a PDF attachment or a secure link as soon as it’s generated.

This bulk-email step takes literally a single click after generation – saving you the hassle of manual emails. In short, Certopus lets you send certificates in bulk by email in a few clicks

Steps:

  • Design certificate: Use Certopus’s online editor or templates to lay out your certificate (logo, name field, date, signature, etc.).
  • Prepare recipient list: Export attendee data (names/emails) from your LMS or event platform into a CSV or Google Sheet.
  • Bulk issue: In Certopus, create an Event and upload the CSV. Confirm the fields (name, email) and hit “Issue.”
  • Email delivery: Certopus.com will generate all certificates and email them. You’ll get delivery status, and recipients receive a polished PDF in the inbox ..

This bulk issue method is designed for speed and reliability. Certopus users report that what used to take hours can now be done in minutes. By automating the process end-to-end, Certopus eliminates errors (no misspelled names) and ensures every participant gets the correct certificate on time.

2. Automate with Integrations (Zapier, Webhooks, etc.)

For an even more automated workflow, use Certopus integrations or API. The platform connects seamlessly with Zoom, Google Meet, Moodle, Google Sheets, and over 1,000+ apps through Zapier or Activepieces.

Here’s how automation works in Certopus:

  • Connect your favorite tools:
    Integrate Certopus with event or learning platforms such as Zoom, Google Meet, or Moodle.

  • Set up an automated trigger:
    Example:

    • Trigger: New Zoom registration or meeting end
    • Action: Certopus generates and emails a personalized certificate.
  • Use Zapier or Webhooks for automation:
    Create workflows (“Zaps”) that send certificates automatically as soon as new participant data is added.

  • Auto-publish certificates instantly:
    Enable “Auto-Publish” in Certopus to send each certificate automatically as an attached PDF or secure link — no manual steps needed.

  • Integrate with LMS or CRM systems:
    Link Certopus to your existing LMS or CRM so that certificates are issued immediately upon course completion or enrollment update.

  • Bulk-send without manual effort:
    Certopus handles all the generation, personalization, and email delivery — ensuring every participant gets their verified certificate right in their inbox.

In short: Certopus automation means your certificates are emailed on autopilot, saving time, reducing human errors, and ensuring a smooth participant experience.

3. Manual Mail-Merge or API (Fallback Method)

If you prefer a manual or customizable workflow, Certopus still makes it efficient to send certificates in bulk through email.

Here’s how you can use Certopus with manual or semi-automated methods:

  • Generate certificates in Certopus:
    Create and export all certificates as PDFs once they’re personalized.

  • Export recipient data:
    Download a CSV file with participant names and email addresses directly from Certopus.

  • Use Gmail or Outlook mail merge:
    Upload the exported CSV and PDFs into your email client to send certificates using mail merge tools like Gmail Merge or Outlook Add-ins.

  • Use Google Sheets Autocrat:
    Combine Google Sheets + Gmail to attach each certificate file automatically for bulk emailing.

  • Custom automation via API:
    Developers can use the Certopus REST API with SMTP scripts to fetch each certificate and send emails from a custom email server or branded domain.

  • Faster than manual sending:
    Even though this approach involves extra steps, it’s still far more efficient than attaching certificates one by one.

In short: Whether you use mail merge or Certopus API, these methods let you leverage Certopus’s PDF generation and personalization features while keeping flexibility in how you send certificates.
