Choosing the Best Postcard Format for Your Campaign

There are many variables to consider when choosing a postcard format for a direct mail campaign. Factors like size, postage rates and design, all play a role in determining the best mailer for your campaign.

Although we see a strong ROI from all of our print products, below are a few of our most popular formats and why we recommend them for direct mail campaigns.

Sumo Size Postcard

Sumo Size Postcard

Maximum Attention. Low-Cost Postage.

Postcard Size: 6″ x 11″

With direct mail, you need eye-catching images and enticing offers to get noticed. Our popular Sumo Size gives you plenty of space to work with and is the largest postcard that can mail at bulk rate postage.

Bonus Tip: Leverage the space to give emphasis to your most importation information and make sure those elements stand out.

Panoramic Double Sumo

Panoramic Double Sumo

Picture Perfect. Space to Spread Out.

Postcard Size: Folds to 6″ x 10.5″

We use this postcard format for a lot of our own direct mail marketing. The interior of the Panoramic Double Sumo is almost two feet in length meaning photos and graphics really stand out while leaving plenty of space for your offer and information.

Bonus Tip: To encourage recipients to read your full message, always include a “See Inside” teaser on the front and mailing panel for folded mailers.

Standard Postcard

Standard Postcard

Rapid Delivery. Effective Advertising.

Postcard Size: 4.25″ x 6″

Perfect for fast campaigns on a budget, our Standard Postcard Size comes with numerous advantages. It mails at First-Class speeds and is cheaper than other sizes. Delivery for the Southwest is usually within 1-3 days and is 3-5 days for nationwide.

Bonus Tip: When you mail at First Class, the USPS also provides free forwarding or returns for outdated addresses (something you can optimize with our mailing list services).
