Politics is loud. It’s a relentless, digital barrage of 15-second unskippable ads, fundraising texts that sound like a crisis, and social media threads that leave everyone feeling exhausted. In the middle of this high-tech chaos, a bunch of people are sitting at their kitchen tables with gel pens. They’re writing postcards. It sounds almost quaint, right? Maybe even a little bit useless when you consider the billion-dollar scale of modern campaigns. But if you actually look at the data, you’ll find that postcards to voters effectiveness is a real, measurable phenomenon that has campaign managers rethinking their traditional "TV-first" budgets.
It works because it’s different.
When you get a piece of mail that is clearly handwritten—not "handwriting font," but actual ink that might have a smudge or a slightly crooked stamp—you look at it. You just do. It’s human nature. In a world of automated everything, a physical card from a stranger in another state saying, "Hey, your vote matters," carries a strange kind of weight. It’s a tactile reminder of the democratic process that a "STOP" reply to a robot text just can't replicate.
The Cold, Hard Data on Handwritten Outreach
Let's talk numbers. This isn't just about feeling good while doodling. Political scientists have been obsessed with "Get Out The Vote" (GOTV) metrics for decades. One of the gold standards in this field is the work of Donald P. Green and Alan S. Gerber, authors of Get Out the Vote!. Their research generally shows that the more personal the contact, the higher the "vote lift."
Historically, door-knocking is the king of turnout. But it’s hard to scale. Phone banking? People don't answer their phones anymore. That’s where the postcard comes in.
Recent studies, including those by organizations like Sister District and Progressive Turnout Project, have tested postcards in "randomized controlled trials." This is the same way we test new medicines. They send cards to one group and nothing to another. What they’ve found is that postcards to voters effectiveness usually results in a turnout bump of anywhere from 0.2% to 1.3%.
That sounds tiny. It’s not.

In a swing district where the margin of victory is 500 votes, a 1% bump across 60,000 voters is the difference between winning and losing. It’s a game of inches. Groups like Postcards to Voters, founded by Tony McMullin in 2017, have facilitated millions of these cards precisely because that small percentage matters so much in a polarized climate.
Why the "Personal" Element Trumps the "Professional"
You’ve seen the glossy campaign mailers. The ones with the candidate looking heroic or the opponent looking like a villain in a horror movie. Honestly, most of those go straight into the recycling bin. They feel like ads. They are ads.
A postcard is different because it isn't trying to sell you a product; it’s a person-to-person nudge. When a voter sees their own name written in ink, it triggers a psychological response called the consistency principle. If someone takes the time to write to you, you feel a subtle, subconscious obligation to at least consider the message.
Also, there’s the "social pressure" aspect, though it’s much gentler than a phone call. Knowing that a fellow citizen is watching the election and cares enough to buy a stamp makes the act of voting feel like a community expectation rather than just a chore on a Tuesday.
What Makes a Postcard Actually Work?
Not all postcards are created equal. If you write a three-page essay in tiny print on the back of a 4x6 card, you’ve lost. The effectiveness peaks when the message is "short, sweet, and specific."
- The "Plan to Vote" Prompt: Research shows that asking someone when or how they plan to vote is more effective than just telling them to do it. "Will you be voting before work or during your lunch break?"
- The Deadline: Highlighting a specific date or a new polling location is high-value info.
- The "Why": A single, non-preachy sentence about why this election matters.
The Sister District Action Network ran a study in 2020 that found "voter-to-voter" postcards were particularly effective for down-ballot races. These are the local elections—school boards, state house reps—that get zero media coverage. In these races, a single postcard might be the only piece of communication a voter receives about that candidate. That's where the ROI (Return on Investment) of a 50-cent stamp really skyrockets.

Debunking the "Waste of Time" Myth
Critics often argue that the time spent writing 50 postcards would be better spent phone banking or canvassing. Is that true? Well, sort of.
If you are a charismatic extrovert who can handle being yelled at on a doorstep, yes, go knock on doors. Canvassing is statistically more effective per contact. However, many volunteers are introverts. They won't make phone calls. If the choice is between an introvert writing 100 postcards or that same person doing nothing because they're too anxious to call a stranger, then the postcards are a massive net win for the campaign.
It’s about "volunteer mobilization." Postcards allow people who are homebound, busy with kids, or just shy to contribute meaningfully. This creates a "long tail" of activism that adds up to millions of additional touches that campaigns wouldn't otherwise have.
The Cost-Benefit Breakdown
Let's get practical. How much does it cost to move one vote?
In the world of political consulting, this is called the Cost Per Vote (CPV). TV ads are expensive and have a high CPV because so much of the audience isn't even in the right district or isn't a registered voter.
- Stamps: The biggest cost. With postcard stamps around 56 cents, sending 1,000 cards costs over $500.
- Labor: Free (volunteer-driven).
- Materials: Cards and pens.
While the CPV for postcards might be higher than a mass email (which is basically free), the "open rate" of a physical postcard is effectively 100%. You have to look at it to throw it away. You can’t "delete" a postcard without it passing through your field of vision. This "forced impressions" factor is a major part of why postcards to voters effectiveness remains a staple of modern grassroots strategy.

Common Pitfalls That Kill Your Impact
If you’re going to do this, don’t mess it up by being "too political." People hate being lectured.
The most effective cards are the ones that sound like they're from a neighbor. Avoid jargon. Don't use words like "infrastructure" or "geopolitical." Instead, talk about "clean water" or "better schools."
Also, timing is everything. A postcard that arrives three weeks before an election is forgotten. One that arrives two days after the election is a waste of a stamp. The "sweet spot" is usually about 10 to 14 days before the polls open—just as people are starting to think about their plans but before their mailboxes are completely overwhelmed by the final-week deluge of junk mail.
The Role of Design
You don't need to be an artist. In fact, "too professional" can actually hurt you. Some data suggests that cards with hand-drawn doodles—a little heart, a flag, or a smiley face—actually perform better than plain ones. It reinforces the "human" element. It says, "A real person sat here and thought about me for thirty seconds."
How to Get Started the Right Way
If you’re ready to test out postcards to voters effectiveness yourself, you shouldn’t just start mailing random people. You need a list. You need a strategy.
- Join an organized group. Don't reinvent the wheel. Groups like Postcards to Voters, Vote Forward, or Postcards to Swing States handle the legalities and the data. They ensure you aren't mailing people who have already voted or people who aren't registered.
- Follow the script. These organizations spend a lot of money testing which phrases work. If they tell you to mention a specific early voting date, do it. They've done the A/B testing so you don't have to.
- Batch your work. Don't try to write 100 in one sitting. Your handwriting will turn into a doctor's scrawl, and nobody will be able to read your message. Write 10 a day. Keep it legible.
- Verify the address. One of the biggest drains on effectiveness is "undeliverable" mail. Make sure you’re using updated voter rolls provided by a reputable organization.
- Focus on the "Low Propensity" voter. Don't waste stamps on people who vote in every single primary and general election. They’re going anyway. The real "lift" comes from writing to people who vote occasionally. Your card might be the nudge that moves them from the couch to the ballot box.
The reality is that postcards won't replace big-budget media buys. They aren't a silver bullet. But they are a proven, scalable, and deeply human way to cut through the digital noise. When you look at the margins of recent elections in places like Arizona, Georgia, or Wisconsin, you realize that those 0.5% bumps aren't just statistical noise. They are the margin of victory.
Writing a postcard is a small act. But multiplied by ten thousand volunteers? That's a movement. It's proof that in the most "online" era of history, a piece of cardstock and a bit of ink still have the power to change a mind—or at least, to start a conversation.
