How to Send More Than One Postcard

Sending Many Postcards? We got you!

Prepare your files

Upload the image file that will be used on the postcards

  • We accept PDF files sized at 4.25" x 6"

  • Or image files: PNG or JPEG images sized at 1875px wide by 1275px high

To add recipients you have 2 options…

  • Upload a spreadsheet of addresses

  • Create a CSV file with each recipient as its own row

  • Use our template to see how to label each column

  • Use the message column for the postcard text

  • Use the service to indicate it is a "USPS_POSTCARD"

  • If you don’t have too many, or don’t want to use a spreadsheet, you can add recipients manually, after uploading the image file, and then link the documents to the recipients.

Sending Multiple Postcards

  • From the Mailform Home page, click MANY LETTERS (or click Services > Bulk Mail) (You will need to create a free Mailform account to send bulk mail)

  • Click TRY IT OUT


  • Upload Postcard images from your computer or from the cloud

  • Choose to import an address file (csv) or click X to add them individually

  • The image files show up on the right side and you can click to add your recipients

  • Click Postcard

  • Click Select Files to set the postcard image to each recipient, or click Add to All under the image file to the right.

  • Click the pencil icon to the right of the recipient row to enter a message and optional barcode link. You can choose to add individualized messages or Update All Postcards with the same message.

  • Once your recipients have all been added, you can click Mail All to proceed to checkout. Or you can click Save For Later, to come back and send at another time.

Postcards are sent with USPS First Class Mail and do not have tracking options. If you upload files that are different dimensions then our system will reformat them as best it can, but for best results, use correct dimensions.
