First confirm which address is yours
A design can be ready before the domain is registered. Before approving a print run, compare the address on the card with the active domain in your account. An available search result does not mean you have purchased it. Check the extension as well: a different letter or dot changes the address the customer will try to open.
Keep the exact spelling in the file sent to the designer and request a final proof. If the name uses ñ or accents, test typing and sharing it through the project’s actual tools. Do not accept a different spelling merely because it is easier to lay out. Decide the address first, then adjust the design around that decision.
Test without your administrator session
Open the address in a browser where you are not signed in to the website builder. A visitor should see the published page, not a preview or a private screen. Test HTTPS and also www if the printed materials include it. Connect the domain and website before announcing that customers can already visit the address.
Use a phone to read the content and complete the main task. On a professional card that might be sending an enquiry; at a restaurant it could be viewing the menu; in a shop it might mean checking a product. Ask another person to try without instructions and fix confusing steps before printing additional copies.
Review the link inside the QR code
Generate the QR code using the final public address and check where scanning it leads. If it uses an intermediate service, review that account, its terms and who will maintain the link. A printed code cannot explain to customers that a supplier changed its destination or that the account managing it has stopped working.
Scan a physical proof at the intended print size using the devices available to you. Review contrast, readability and the destination. Include the written domain where the design allows, for people who prefer typing it. Avoid preview links, administrator addresses and temporary campaign pages that will disappear when the promotion ends or the project changes tools.
Check how customers can reach you
If printing a domain email address, first verify that its mailbox exists and receives messages. Send an enquiry from an external account and reply from the mailbox. For a contact form, test submission and confirm delivery to the team. Seeing a success message on the page is different from establishing that the enquiry reached its intended inbox.
Review what the printed material promises: opening hours, support language, the service and any specific page address. Do not include a contact route you cannot yet manage. Keep a straightforward path for someone who types the root domain manually, so they reach useful information without needing the QR code or a particular campaign link.
Keep a proof and check again later
Keep the final approved proof, the QR destination and the completed checklist. Record who administers the domain, website and email, along with renewal dates. If an agency is involved, request a handover identifying those services. Keeping printed material useful depends on maintaining the address and its destination after the initial design work has finished.
Repeat the test with an already printed card after changing hosting, nameservers or page structure. Check that old links still reach their intended destination. If the project is just starting, check a .es name and confirm registration before producing materials. Reviewing a proof is easier than correcting every copy after it has been handed to customers.
