Who we are
Greetings from S2S is a service of Sustainable 2U Inc dba Mail Stop, operated from the Mail Stop store at 6017 Snell Ave, San Jose, CA 95123.
What we collect
When you order a card, we collect your name, email, the recipient's name and mailing address, your message, and the mail date you choose. If you email us a photo, we receive that photo. Dates you save in the “My dates” list are stored only in your own browser and never sent to us.
How we use your information
We use your information only to print, stamp and mail your cards on the date you choose, and to send you the secure payment link by email. We do not sell or share your addresses or personal information with anyone for marketing.
Payment
We send a secure payment link by email within one business day. Payment is handled by our payment provider — we do not store your card details in this app.
Photos
If you send a photo, you confirm you have the right to use it. We use it only to print your card.
Your choices
You can ask us to update or remove your information at any time by emailing hello@mailstop.ai.
