We’ve always been big fans of email as a marketing channel that retail businesses should use to connect with and nurture their audiences. Two years ago, we wrote about using email to bring local shoppers through your door. We’ve also shared ideas and articles on email segmentation and personalization. Over the past few years, advances in technology and AI have made the inbox the starting point for connecting with and nurturing your customers. Today, you can build those relationships across multiple channels in a more strategic and personal way.

In January 2026, Google brought its Gemini AI into Gmail, adding summaries that condense long threads, one-click replies, and an AI-organized inbox view still in limited testing. Apple has been preloading email images since 2021, which inflates open rates and hides where your readers are. At the same time, shoppers are paying closer attention to their physical mailboxes. Lob’s 2026 consumer research found that 84% of consumers say higher prices have changed how they shop, and 68% are paying closer attention to what lands in their mailbox.

According to Faire’s Independent Retail Report from July 2026, independent retailers with physical stores are growing faster than online-only sellers, with small towns outperforming major cities. Maintaining a local presence gives you an edge, and the email list is more valuable than ever because it can now reach customers through three different channels. This enhances the likelihood of being remembered, and the principle of repetition—or the rule of 7, an old marketing adage—allows you to reinforce multiple reasons for customers to choose your store.

Your List Is an Asset, Not Just a Send Button

Everything starts with a list you can apply to other platforms. Keep doing what already works in your store: QR codes at the register, a small incentive at signup, loyalty program enrollment, or a cross-promotion with other local businesses.

Rethink how you approach email sign-ups. You can do this in two steps: the initial sign-up should have fewer fields, typically just Name and Email, to make it easier for users to provide their information. The second step is to gather more information, such as a full mailing address and what you want to know about the customer, such as life stage or interests. Consider a value exchange to encourage this request; it makes it easier to ask for more detail. Incentives can include exclusive access to events or experiences, early access to sales, or entry into a drawing for a gift or a gift certificate to your store.

While you are at it, check your signup language. A single consent line covering email, direct mail, and advertising keeps you compliant across multiple channels. Have your attorney review the wording and make sure your privacy policy matches your activities.

Most importantly, connect your point of sale to your email platform so your records stay current. A list full of stale addresses impacts your data and increases platform fees, even when you are only sending email. But it becomes a significant expense when you start printing and mailing, including postage.

Write for an Inbox That Summarizes Before It Shows

Your marketing emails now have an email evaluator or scanner before your customer opens your message.

Gmail’s AI Overviews summarize conversations in a few lines, while Apple Mail’s privacy protections generate machine opens and hide IP addresses. While neither change constitutes a crisis, together they modify two crucial elements: the credibility of your reports and your writing approach.

Segment by the ZIP code you collected, not the location your tool inferred. Because Apple masks IP addresses, any geography your email platform reports based on email activity is unreliable. The ZIP a customer typed on your signup form or gave your associate at checkout is accurate zero-party data. Build your local segments from what is provided to you directly.

Judge engagement by clicks, not opens. Delivery, bounce, and click data are still accurate. Open rate is not. If your re-engagement flows, your sunset rules, or your most-engaged segment are built on open behavior, rebuild them on clicks and purchases. You will find the segments get smaller and far more accurate. This means you need to design emails to have more calls-to-action and better-quality dynamic product or content insertion to motivate clicks.

Front-load what matters. We used to say don’t bury the lead; that advice is still accurate: put the offer, the date, and the store location in your subject line or preview copy sections or in your first two sentences of the message above the image that needs to download. People like AI scan their inboxes, especially on mobile; anything buried below the fold may never be seen.

Pair Your Emails with the Mailbox

This is where your list stops being only an email list and becomes a way to build your relationship in the physical world.

Direct mail has grown over the years as a channel that can build interest. Today’s customers can now receive more personalized messages delivered to their mailbox, not just their inbox. This channel gives retail businesses a way to connect with customers through another sense: touch. This will continue to build market and message consistency, and the repetition customers need to remember when they decide to shop.

If you use Klaviyo, you can trigger a direct mail flow tailored to your goals. Platforms such as PostPilot, Poplar, and BirdseyePost integrate with Klaviyo and are available in the marketplace, so the segment you defined for email becomes a mailing list without exporting a spreadsheet or doing any extra work. One note: your website traffic and mailing lists will need to reach a certain level to leverage this feature.

Here are four Ideas to consider:

The welcome postcard. A customer signs up at the register or on your website and gets your welcome email. A week or 10 days later, a postcard arrives with a reason to shop your store again. The second touch is physical and shows an existing customer or potential customer you value them.

The win-back postcard. A customer has not clicked on any of your recent emails, or they have not purchased in the last 90-120 days. You should run an email win-back flow first, and then if it does not convert, trigger a postcard a week later. This is a targeted, easy, high-quality way to connect with your customer via direct mail, because the audience is small and everyone has purchased from you before.

The purchase anniversary card. A handwritten note on the anniversary of a meaningful purchase, reminding them of something related to the appointment or the piece they purchased. Most businesses focus on emails and messages around customer birthdays and personal anniversaries, which is great, but this approach will differentiate you from other brands; it’s low-volume, high-impact, and especially strong for jewelry, furniture, and any purchase that marked a specific occasion.

The event invitation. Mail the printed invitation first, then send the email or SMS reminder. This is ideal for VIP audiences. The physical mail piece creates the sense of occasion. The email and SMS handle the logistics of time, parking, and RSVP reminders.

Two items worth noting. USPS Informed Delivery sends recipients a daily email preview of the mail headed to their home (I signed up for this because I travel so often and love it), so your postcard can appear in their inbox before it reaches their door. This is two channels working together for free.

And the Postal Service is actively discounting postage rates to motivate businesses to send more mail; yes, even the USPS is running special offers. The First-Class Mail Advertising promotion offers 5% off from September 1 through December 31, 2026. The Continuous Contact promotion offers 5% on follow-up mailings that build on an initial piece, running through December 31. Enrollment happens through the Business Customer Gateway, and most commercial printers will handle the paperwork for you if you ask.

Though I’ll admit not everyone will scan, you should consider adding a tracking option to your print pieces. Gaining a percentage of scans is better than none. To improve that number of scans, call out an exclusive offer or special story via the QR code on your direct mail pieces. The code should send the customer to a unique page with something they cannot see anywhere else. A few weeks after each mailing, get in the habit of cross-checking direct mail addresses against your sales. Create a dashboard and measure this quarterly to understand the big picture.

Now Add a Third Medium – TV

Streaming TV used to require an agency relationship and a significant six-figure commitment, but that is no longer the case.

Self-serve platforms now let you run ads on streaming apps targeted to specific ZIP codes, or to your own customer segments. Vibe*, for example, connects directly to Klaviyo, so a segment such as subscribers who have never purchased can become a streaming audience.

These platforms match your customers to streaming households, and only profiles with certain data can be matched, similar to what I shared above with direct mail. A small list of 800 subscribers may reach very few screens, and retailers with larger lists, steady website traffic, and higher-ticket products get considerably more out of this than a business that just started collecting emails six months ago.

Creative doesn’t have to be expensive either; a Reel you already produced can run as a streaming ad and may provide the authentic feel big-box stores can’t.

An Inspired Approach for This Holiday Season

This example shows how three channels can be coordinated around a single in-store event. No additional staff is needed, and all components utilize the same audience and message.

Timing	Channel	Audience	Message
3 weeks out	Email	VIP and local ZIP segments	Save the date for the holiday open house
2.5 weeks out	Postcard	Same segments	Printed invitation with a unique offer code
2 weeks out	Streaming TV (optional)	Local ZIPs and subscribers who have not clicked	Short video preview of the event
Event week	Email and SMS	Everyone invited	Reminder with hours, map, and parking
After	Handwritten card	Event buyers	Thank you and an invitation to come back

Measure Conversions and Outcomes

Clicks, offer code redemptions, store visits, appointments booked, and sales matched back to the direct mail list. These are a great way to measure your success. Tying this in with call tracking and cross-referencing online sales will give you additional ways to check the success of the multichannel campaigns.

One idea worth considering as an additional test of this approach is to hold back roughly 10% of your audience from the mail piece or the streaming ad and send the email to everyone. Compare the behavior of the two groups. That comparison tells you whether the second channel added anything or whether email was doing the work. This additional step can help you better understand the metrics and the difference between knowing and guessing.
