Instructions - 4x6 Postcard


PDF Creatives

PDF creatives must be submitted as a PDF file with two pages in the PDF file - one for the front of the post card (page 1) and one for the back (page 2). The front of the post card is free form. Both sides of the card must have a 0.25 inch bleed on all sides. The final PDF page size must be 6.5 inches wide and 4.5 inches tall.

The back of the post card has specific layout restrictions. Please use the image below for guidance in creating the layout for the back of the post card.

PDF creatives do not support dynamics variable injection.

HTML Creatives

Unlike PDF creatives, HTML creatives allow for dynamic injection of variables into the creative based on this guide. HTML creatives also do not require advanced graphics editors and can be created using a simple text editor.

With HTML creatives, you will need to create two separate HTML pages: one for the front of the post card and one for the back of the post card. The HTML template for the front of the post card can be accessed here. Sample HTML for the front of a card can be located here. The HTML template for the back of the post card can be accessed here. Sample HTML for the back of a card can be accessed here. When HTML creatives are used, all variables are merged into a PDF document and distributed to mail houses in PDF format for mailing. Using the sample front and back HTML provided here, the final PDF file would look like this.

It is important to note that all images and resources in your HTML file must be hosted on an always-available CDN, such as Amazon S3, as creative generation happens real time and all resources must be available at all times. If you need assistance on hosting images or other resources, please contact us.
