What we collect
To mail a greeting card for you, we collect the sender's name and email, the recipient's name and mailing address, your personal message, and any photo you choose to include. We collect exactly what we need to print and mail your card — nothing more.
How we use it
We use your names, addresses, messages, and photos only to fulfil your order — printing your card, addressing the envelope, and mailing it. We also use your email to send your secure payment link and order confirmations.
Your addresses are never sold
We never sell your information, and we never share recipient addresses with anyone else. They're used to mail your cards and nothing else. E-card emails contain only your greeting — no marketing, no tracking beyond what's needed to send it.
Photos and your right to use them
When you send us a photo, you confirm that you have the right to use it. We print it on your card only and don't store it longer than needed to fulfil your order.
"Mailed by," not "delivered by"
Mail dates mean we print, stamp, and mail your card on that day. First-Class mail usually takes 2 to 5 days, but we can't promise an exact delivery date — only that we'll send it on time.
Keeping in touch
The Card Club stores up to 25 saved dates so we can send you reminders 14 and 5 days before each one. You can update or remove those dates any time by emailing us.
