Frequently asked questions
What's the fastest way to get help?
Email support@zentez.io with your account email and, if relevant, a certificate ID or batch name — that lets us look into it immediately instead of asking follow-up questions first.
How long until I get a reply?
Within 1 business day. Most billing and account questions are resolved same-day.
I received a certificate and think it's spam or unwanted.
Email support@zentez.io with the certificate ID or the email it arrived in, and ask us to remove your data. We'll act on removal requests promptly and can also flag the sending account for review.
Can I request a refund through this page?
Yes — email support@zentez.io with your account email and order details. See our refund policy for what's eligible.
Do you offer phone or chat support?
Not currently — email is the fastest and most reliable way to reach us, and it gives us a written record to act on.
