How to Create a Postcard Mailer for Your Campaign

4/29/2026

Key Takeaways

• A postcard mailer is a printed card sent through the mail to promote an event, fundraiser, business, or campaign.
• Postcards stand out over email because of their physicality. They arrive in someone’s mailbox, and are interacted with in a tactile way email can never replicate.
• Eventgroove offers two ways to use postcards: USPS First-Class direct mail using your CSV mailing list, or printed postcards shipped to you for hand distribution and product-box inserts.
• Eventgroove postcards come in two sizes: a standard 4.25″ x 6″ (every template, lowest USPS postage rate) and a larger 5.5″ x 8″. Most mail campaigns work fine at the standard size, though if you’d like premium positioning the larger dimensions can have more impact.
• Per the Data & Marketing Association, postcard mailers average 4.25–9% response rates which is well above most email benchmarks. They also pair especially well with QR codes for tracking and response.

In a world of overflowing inboxes and ad-blocked everything, a printed card that arrives in someone’s mailbox gets held and remembered in ways unmatched by digital media. For events, fundraisers, political campaigns, businesses, and nonprofits, a postcard mailer is one of the most reliable ways to put your message in front of the right people.

This guide walks through exactly how to create one, from choosing a size, designing it, and writing copy that converts to getting it printed and delivered. Whether that means we mail it for you or ship it to you to distribute is up to you.

What Is a Postcard Mailer?

A postcard mailer is a printed card sent directly through the mail without an envelope. One side carries a marketing message, event announcement, fundraising appeal, or campaign statement. The other side carries the recipient’s address and postage. Postcard mailers are cost-effective for high-volume campaigns and visually impossible to ignore — recipients see your message the moment they pick up their mail.

Two Ways to Send Postcards with Eventgroove

You don’t have to mail your postcards yourself. We offer two methods:

• We mail them for you (USPS First-Class direct mail). Edit one of our customizable postcard templates or upload your print-ready files, then add your CSV file, approve the proof, and we’ll print, address, and mail your postcards via USPS First-Class.
• We ship them to you. We print your postcards, then box them up and ship them wherever you’d like. Best for hand distribution at events, in-person canvassing, dropping into product boxes as a thank-you note or upsell, leaving in local businesses, or any scenario where you control delivery.

Both use the same templates, sizes, paper stocks, and design tools. The only difference is who handles the mailing.

Direct Mail vs. EDDM

You may have seen “EDDM” (Every Door Direct Mail) mentioned. EDDM is a USPS service that lets you mail postcards to every address on a postal route without needing an address list. It’s useful for blanket geographic targeting “every household in this zip code” but it doesn’t let you target specific individuals or use your own mailing list.

Eventgroove offers USPS First-Class addressed direct mail, not EDDM. That means you bring (or build) your mailing list and we deliver to those exact recipients. For fundraisers reaching specific donors, political campaigns reaching registered voters, businesses reaching past customers, or events reaching ticket buyers, addressed mail is almost always the better fit. Since your message is being sent to people who already have a relationship with your brand, you can expect better response rates. If you need true EDDM, USPS lists certified providers on their site.

How to Create a Postcard Mailer

Postcard mailers can be a great way to reach people, but if not done correctly, they can end up feeling more like generic leaflets than a way to improve your campaign and message. The steps below walk through how to make yours land.

Step 1 — Define Your Goal and Audience

Before you design anything, get specific about what the postcard is supposed to do and who it’s for.

“Sell more tickets to the spring gala” is a goal. “Reactivate lapsed donors who haven’t given in 18 months” is a goal. “Reach voters in Districts 4 and 7 ahead of the November election” is a goal. “Build awareness” is not a goal — at least not one you can measure.

Once your goal is clear, define your audience just as specifically. Knowing exactly who you’re writing to shapes every decision that follows: which size, which images, which words, which call to action.

Step 2 — Choose the Right Size

Eventgroove offers two postcard sizes: a standard 4.25″ x 6″ (the size every pre-designed template prints at, and the size that qualifies for the lowest USPS First-Class postcard rate) and a larger 5.5″ x 8″ format available through our postcard maker.

Pro tip: If you’re A/B testing, run the same design at both sizes through Design Your Own and track response with separate QR codes or promo codes.

Step 3 — Design Your Postcard

Strong postcard design is mostly about restraint. Pick one message and lead with it. Use your logo and brand colors so recipients recognize who it’s from at a glance. Leave white space — clutter kills response rates. Make sure the most important information (event name, date, offer, deadline) is readable in two seconds, because that’s all you’ll get.

This is where our fill-in-the-blank templates come in handy. They’ve been laid out with design in mind. All you have to do is pop in your own text, images, and QR code.

Step 4 — Write Copy That Converts

Headline first. The reader gives you about a second to decide whether to keep reading or toss the card, so the headline has to do the heavy lifting. Be specific — “Save $200 on registration through April 15” beats “Don’t miss our event.” Lead with the benefit, not the brand.

Body copy should be short. Think 30–60 words, not paragraphs. Cover the what, when, where, and why-now, and skip everything else. Close with a clear, single call to action: “Register at example.org,” “Scan to donate,” “Bring this card for 20% off.” A QR code is almost always worth including, both for response tracking and capitalizing on the moment someone feels inspired to take action.

Step 5 — Choose: We Mail It, or We Ship It to You

If you have a mailing list, upload it as a CSV and we’ll handle USPS First-Class addressed direct mail end-to-end, with FREE address correction included. If you’d rather distribute the postcards yourself (at an event, in product boxes, by hand, through local businesses), select the ship-to-you option and we’ll print and ship them to you on the same one-business-day turnaround.

When to use each path:

• Mail it for me works for targeted campaigns where you have or are building a list — donor outreach, voter contact, customer reactivation, event invitations to ticket holders, lapsed-donor reengagement.
• Ship to me works for in-person distribution opportunities — product-box inserts, walk-up tabling at events, drops at local businesses, in-person canvassing, or anywhere you want to control the timing and location of distribution yourself.

Step 6 — Track Results

A postcard campaign you can’t measure is a campaign you can’t improve. Bake tracking in from the start:

Studies have shown an email follow up to your mailed postcards can boost response rates by up to 70%. So, you’d start with your direct mail postcards, then, as a low-key reminder to anyone who hasn’t responded email a follow-up a week later mentioning the card

Are Postcard Mailers Still Effective?

Yes — and the research is unusually clear on this. Canada Post’s neuromarketing research found that brains process physical mail 21% faster than digital advertisements, and brand recall was 70% higher for physical mail (75%) compared to digital ads (44%). A ScienceDirect study of postcard campaigns measured a 2.7% response rate, already above most digital marketing benchmarks. The Journal of the Academy of Marketing Science similarly confirms that direct mail offers superior ease of processing, greater brand recall, and higher response rates than digital communication.

The Data & Marketing Association puts the average postcard mailer engagement rate at 4.25–9% depending on audience, with higher rates for existing customers than for new prospects. Pair postcards with QR codes or unique URLs and direct mail becomes one of the few channels where response can be attributed precisely.

Pro Tips for Higher Response Rates

• Add a QR code linked to a UTM-tagged landing page to track every scan.
• Personalize where you can. Even a recipient’s first name on the card measurably improves response.
• Send a follow-up. Mail alone works; mail + email + reminder works substantially better.
• Include a deadline. Urgency drives response — a clear “by ” almost always outperforms an open-ended ask.
• Combine print and digital. Print works even better when it complements digital — see our take on why print and digital marketing belong together.

Postcard Campaigns by Use Case

Most postcard mailer campaigns fall into a few patterns. Where we see customers get the most traction:

Nonprofits and fundraising. Donor appeals, gala invitations, year-end giving, walk-a-thon promotion, and lapsed-donor reactivation are some of the highest-ROI uses. The 10% nonprofit discount applies to fundraiser postcards.

Political and voter outreach. Political mailers handle candidate introductions, GOTV reminders, and ballot measure campaigns — addressed direct mail beats EDDM here because you’re targeting registered voters specifically.

Local businesses, real estate, and restaurants. Grand openings, neighborhood mailers, “we just moved” announcements, and restaurant postcards promoting specials and events all work well.

Events, schools, and community organizations. Use event postcards for concerts, theatre, and conferences. Church postcards are terrific for service invitations and outreach.

Seasonal and holiday campaigns. Holiday postcards cover Christmas, Valentine’s, and 4th of July; seasonal postcards handle spring, summer, fall, and winter promotions.

For Nonprofits Specifically

If you’re running a nonprofit campaign, direct mail tends to outperform digital for donor reactivation, year-end giving, and major-donor cultivation. We covered the full strategy on the Fundraising blog: 5 Reasons Direct Mail Benefits Your Nonprofit. Worth a read if direct mail is part of your fundraising mix.

Conclusion

Done well, a postcard mailer is one of the highest-leverage tools you can put in a marketing or fundraising campaign. Start with a clear goal, pick a size that fits your message and budget, write copy that earns the next two seconds of attention, and decide whether you want us to mail it or ship it. We handle the rest — design tools, templates, printing, addressing, mailing.

Frequently Asked Questions

What’s the difference between First-Class direct mail and EDDM?

First-Class direct mail uses an addressed list — you tell USPS exactly who should receive each card. EDDM (Every Door Direct Mail) sends to every address on a postal route without an address list. First-Class is best for targeted campaigns (fundraising, political voter outreach, customer reactivation); EDDM is best for blanket geographic mailing where you want every household in an area regardless of who they are. Eventgroove offers First-Class addressed direct mail.

What’s the average response rate for postcard mailers?

According to the Data & Marketing Association’s Response Rate Report, postcard mailers typically achieve 4.25–9% engagement, depending on your audience, with higher performance for existing customers compared to new prospects.

How do I measure the success of my postcard mail campaign?

Track results using unique URLs, QR codes, or specific promo codes to see engagement and conversions directly tied to your mailers. For donor or customer mailings, segment your list and track response by segment so you can see which groups respond best.

Can I get my postcards shipped to me instead of mailed?

Yes. If you’d rather hand-distribute your postcards (at an event, in product boxes, through local businesses), select the ship-to-you option and we’ll print and ship to you on the same one-business-day turnaround.
