Bulk Domain Import for SSL Monitoring

Adding 60 client domains one by one takes 40 minutes. That's the onboarding experience that makes people not bother.

CSV import gets you from a spreadsheet of domains to active monitoring in under two minutes. One domain per row, upload the file, and Expiron starts checking certs immediately.

Works for any number of domains. Onboarding an MSP account with 200 client domains is the same process as adding 10.

  • One domain per row in the CSV — no headers required. Upload and monitoring starts immediately.
  • No limit on import size on Pro plan — onboard 10 domains or 500 in the same operation.
  • Includes subdomains — each subdomain is a separate entry, same as adding manually.

Common questions

What format does the CSV need to be?
One domain per row, no headers required. Expiron reads the domain name and ignores everything else.

Yes. Each subdomain is a separate entry, same as adding manually.
