Direct Mail Best Practices
Purchasing our turnkey direct mail solution?
Here is an overview of the best practices for direct mail.
In this article, we will review best practices to help users discover your Art House direct mail campaign while complying with USPS’ direct mail regulations.
USPS has very strict guidelines for direct mailers. Be sure to follow these guidelines, ensuring that your dot the i’s and cross the t’s.
In regards to promoting your AR activation, we suggest using a combination of these on the back of your direct mailers to ensure users are aware of your activation and it is a frictionless experience. An example would be using a Call-To-Action and a QR Code and / or NFC tag. These also are not the only ways to promote your project, so get creative!
Designing Your Direct Mailer
USPS has a lot of rules and regulations for their Every Door Direct Mail (EDDM) service. It is important to follow all of these when designing your direct mailer. In this section, we will outline the various requirements.
*If you are not using the USPS Every Door Direct Mail (EDDM), but using a mailing list instead, you can disregard this section. When not using USPS' EDDM service, you are essentially sending standard mail and do not need to follow these guidelines. Speak with your account manager for more details.
Mailer Sizing
With our turnkey direct mail solution, we currently standardize the size of our direct mail for simplicity. We use the most common size, which is 6.5" by 9".
If you'd like to customize this, please speak to your account manager and reference the below guidelines.

-
Rectangular with four square corners or finished corners that do not exceed a radius of 1/8 inch. Must be one of the following: more than 11.5 inches long OR more than 6 1/8 inches high OR more than 1/4 inch thick. (Note: If an 8 1/2 x 11 piece is folded in half, the final dimensions would not be a flat-sized piece.)
-
Cannot be more than 15 inches long, 12 inches high, or 3/4 inch thick.
-
Cannot weigh more than 3.3 ounces when submitted at the local Post Office.
Indicia Placement
Instead of using precanceled stamps or a postage meter, the mailer prints postage information in the upper right corner of the mailpiece. This postage block is called an "indicia." The indicia are printed onto each mailpiece and should be included in your design.

-
Orientation of the address does not matter, i.e., whether the address is applied parallel to the long or short side of the piece. However, the address must be in the top half of the piece.
-
The shortest end will always be the top half of the piece. Length is always the long side.
Indicia Design
USPS has specific indicias for specific types of direct mail. Contact your account manager if you need assistance choosing the proper indicias. Click the examples below to download.

Promoting Your AR Activation
Promoting your AR activation might be the most important piece of the puzzle. It is important to include a clear and concise call-to-action on the back of your direct mailer. To improve the user experience, we suggest including tools such as QR codes or NFC tags linked to our Immediate Experience to make the activation frictionless. In this section, we’ll dive into each of these in detail.
Call-To-Action (CTA)

Tell users what they stand to benefit from scanning (what is the value proposition). Use phone graphics (like the one above) to make the action of scanning clear. Put yourself in the shoes of the user. In the context it’s placed in, would someone scan it? If the answer is ‘no’, you probably need to go back to the drawing board to ensure the QR code is visible and the call to action is incentivizing scanning.
What we have found is that the success of an AR project can have everything to do with the process and communication. Creating this clear and effective Call to Action is part of what we call the 5 C’s for Success:
Context - Put yourself in the shoes of your end user in the exact moment of
assistance and ask yourself what that moment would feel like: do you have a hand
free at the moment, good network connectivity and the dwell time to make it a
positive scanning experience?
Control - How well can we control this context: the lighting, the image itself
being scanned, the distance of the user from it, occlusion, the acoustics, file size
etc. The more control we have in that context the better the end user experience.
Remember that when it comes to AR, the experience will only be as good as what the camera on the device can see at that scanning, detection, initialization and tracking moment.
CTA - Make sure the Call to Action clearly tells people HOW to scan and WHAT
they are going to get for their efforts. Make sure the CTA is connected to the image
or place you’re asking people to scan. The greater the distance from CTA to scanning
moment the greater the drop-off in activation. Getting the CTA right is crucial. This
is the C that on the surface seems the simplest to get right but 9/10 is left too late
or not thought about deeply enough. Remember that no one is looking for (or cares
about!) your AR experience so be very clear about what you are asking them to do
and what they’re going to get.
Content - Make sure the content you are delivering is valuable to your users
and could not have been more easily accessible or better delivered by just going to
your website or YouTube channel! Reward them for their participation with digital
value add or real world value (sweeps, coupons etc.) and offer levels of immersion,
engagement and interaction that make AR so powerful.
Communications - Make sure to leverage your other comms channels
to tell people about this new camera capability (through POS, Print, TVCs, social,
online ads, influencers, PR, internal comms etc.). This is a new behavior for your
audience so help them understand the benefit and how they can participate.
Remember, beyond your core consumers, your internal audience and sales staff are
your most powerful advocates for spreading the message. We find that when there are failures or shortcomings in a campaign, going back and revisiting how everyone collectively performed against the five C’s is instructive to improving for the process going forward.

QR Codes

Promoting your AR activation might be the most important piece of the puzzle. It is important to include a clear and concise call-to-action on the back of your direct mailer. To improve the user experience, we suggest including tools such as QR codes or NFC tags linked to our Immediate Experience to make the activation frictionless. In this section, we’ll dive into each of these in detail.
NFC Tags

Users can tap their mobile device on NFC tags that you place on or near your Art House activated item to launch an Art House Immediate experience, even from the lock screen. Currently, NFC tags have a reach of about 4 inches. Be sure to include the universal NFC icon near the tappoint to let users know it is available and to avoid any confusion.
