Watch out for

The PDF generator might fail if special characters in names are not escaped properly so sanitize input strings before passing them to the template.
Email delivery can be delayed or blocked by spam filters so configure SPF and DKIM records for your sending domain.
The Data Table may grow large over time which slows down verification queries so add an index on the certificate ID column.
Webhook retries can cause duplicate certificates to be issued so implement idempotency checks using the candidate email or a unique hash.
