Card Mailer

Card Mailer prints 5x7 photo postcards and mails them by USPS First-Class to a list of US addresses.

Share a photo, the greeting and message for the card, and your address list. The list can be a spreadsheet (.xlsx), a CSV export from Google Contacts or Outlook, or addresses pasted one per line. Card Mailer:

• reads the names and addresses, checks required fields and US address format, and shows which rows need fixing. The result states whether a USPS check was performed. You can correct them in the chat or in the table
• shows the front (photo and greeting) and the back (message and sign-off) before you order
• gives the total, the send date and the expected arrival window. If the cards must arrive by a certain day, it gives the latest send date
• creates an order and gives you a link to cards.onmax.me, where you review the recipients and pay. Nothing is printed or charged before you pay
• tells you whether an order has been paid, printed, mailed or delivered

For families sending holiday cards and small businesses sending thank-you cards to clients.

Limits: US addresses only, including APO/FPO. Up to 300 recipients per order. Postcards only, with no envelopes or folded cards. Not for e-cards or email, and not for advertising mail to people who have not asked to hear from you. The USPS address check cannot tell whether someone has moved. Delivery dates are USPS estimates. Recipient addresses are deleted 30 days after the send date, and lists that are never ordered are deleted after 14 days.
