Voters face an overload of emails, texts, and online ads, but one old-school method is quietly making a big difference: postcards. 

So how do postcards to voters work? Does this simple piece of mail really help drive voter turnout? The answer is yes. 

Let’s break down why political mailers continue to play a powerful role in modern elections.

Postcards to Voters and The Power of Tangible Mail

Postcards land directly in voters’ homes and often stay there. They serve as a constant reminder, especially in the final days before an election. That might seem small, but in a tight race, it can be the deciding factor.

Additionally, sending them a reminder of civic duty can encourage them to check registration deadlines, research candidates, or plan to vote

So do political postcards work? Absolutely—it even works on infrequent voters or encouraging early voting and registration. This is especially true when the postcards come from volunteers or grassroots campaigns, creating a peer-to-peer connection that digital ads can’t replicate.

Voters are more likely to take action when they feel personally seen. That’s one of the reasons political campaign postcards work so well: they feel direct, intentional, and thoughtful.

Designing and Sending Political Postcards the Right Way

A successful political postcard design grabs attention immediately and delivers a clear, concise message. Here are a few best practices:

• Keep it bold and readable: Use large fonts, high-contrast colors, and eye-catching visuals.
• Stick to one message: Focus on a single call to action—whether it’s “Vote Early,” “Support [Candidate’s Name],” or “Register by [Date].”
• Make it personal: If possible, include handwritten elements or use a friendly, conversational tone.
• Include all necessary details: Date of the election, voting deadlines, or candidate info.

And don't forget about the legal side. Yes, political mailers are subject to strict regulations. Every postcard must include a disclaimer that clearly states who paid for it (this is usually required by the Federal Election Commission). It’s also important to avoid misleading claims and ensure that all voter information is accurate. Working with an experienced printer or mail house can help you stay compliant.
