So You Want to Help — But Which Method Is Actually Worth Your Time?
You've decided to get involved and help boost voter turnout. Great. But when you start looking into volunteer options, you quickly discover there are a lot of ways to help: write postcards, knock on doors, call strangers on the phone, send texts. Each method has its advocates, its trade-offs, and its own body of research behind it.
This guide cuts through the noise. We'll compare four major voter outreach methods — postcard writing, door knocking, phone banking, and text banking — across the dimensions that matter most to volunteers: effectiveness, time commitment, accessibility, and how they fit into real life.
By the end, you'll know exactly which method (or combination) is right for you.
A Quick Note on the Research
Political scientists have been studying Get Out the Vote (GOTV) tactics for decades. The foundational research — a landmark field experiment by Gerber and Green in New Haven — tested canvassing, direct mail, and phone calls head-to-head on over 30,000 registered voters. Later studies, including work by the Progressive Turnout Project and the Environmental Voter Project, have added nuance specific to volunteer-driven postcard campaigns.
Here's the headline finding: personal contact works best, but it's also the hardest to scale. Everything else is a trade-off between effectiveness and reach.
Method #1: Postcard Writing
How It Works
You handwrite personalized messages on postcards to low-propensity voters — people who are registered but don't vote consistently. Volunteer organizations like Postcards to Voters and Progressive Turnout Project provide you with voter names, addresses, and suggested message templates. You supply the postcards, pens, and stamps, and mail them yourself.
Effectiveness
Research from the Progressive Turnout Project across multiple election cycles shows that handwritten volunteer postcards boost Democratic voter turnout by an average of 1–1.3%. Their 2024 program alone added an estimated 200,000 votes. The Environmental Voter Project's multi-year study (2022–2025) found that postcards using "loss aversion" messaging — reminding voters of a past election where they voted, and what's at stake now — were particularly effective with low-propensity voters.
The key is the handwritten element. Unlike printed political mail, a handwritten postcard signals that a real person took time to write specifically to that voter. That personal quality drives its effectiveness.
Time Commitment
Highly flexible. Most volunteers write 20–30 postcards per hour. You can do it while watching TV, at a postcard writing party, or during a quiet Saturday morning. There are no scheduled shifts and no one waiting on you. You write at your own pace and mail when you're ready.
Accessibility
Excellent. You don't need to leave home, drive anywhere, or talk to strangers. It's ideal for people with mobility limitations, anxiety about confrontation, irregular schedules, or who live in rural areas far from campaign offices. It's also a great gateway activity for people new to civic volunteering.
Cost
Moderate. Volunteers cover the cost of postcards and stamps. At roughly $0.61 per stamp plus the cost of postcards, you're looking at about $1–1.25 per postcard mailed. Many volunteers budget $25–50 for a batch of 25–50 postcards — a meaningful contribution for the price of a dinner out.
Best For
Volunteers who want flexibility, prefer not to engage in real-time conversations, and want a tactile, satisfying way to contribute from home. Also excellent for group events — postcard writing parties are one of the most popular volunteer social activities in civic organizing.
Method #2: Door-to-Door Canvassing
How It Works
You show up in person at voters' doors — typically with a tablet or clipboard loaded with voter contact information — and have brief conversations about voting, local issues, or upcoming elections. Campaign organizations assign you a "turf" (a list of addresses in a specific neighborhood) and you walk it during a scheduled shift.
Effectiveness
Door-to-door canvassing is the most effective single GOTV tactic studied. The Gerber and Green New Haven experiment found canvassing increased turnout by roughly 9.8% among contacted voters — far exceeding mail or phone. More recent research consistently confirms that face-to-face contact is the gold standard for voter mobilization. The 2025 New York City mayoral race saw Zohran Mamdani's campaign field 50,000 volunteers who knocked approximately 1 million doors — widely credited as a decisive factor in his primary victory.
Time Commitment
High. Canvassing requires scheduled shifts (usually 2–4 hours), transportation to a staging location or turf, and physical stamina for walking routes. Most campaigns run canvassing on weekends and some weekday evenings.
Accessibility
Limited. Door knocking requires physical mobility, availability during specific windows, proximity to campaign activity, and a willingness to knock on strangers' doors. It can be challenging in rural areas with spread-out housing, and urban apartment buildings often restrict access. Some volunteers also find it emotionally draining, particularly when doors are slammed or conversations turn hostile.
Cost
Low direct cost to the volunteer (campaigns typically provide materials), but your time investment is significant. Campaigns themselves bear high costs — coordinating canvassers, printing materials, training volunteers, and managing turf.
Best For
High-commitment volunteers who are comfortable with face-to-face interaction, can work scheduled shifts, and live near campaign activity. Ideal for people who want the highest-impact single interaction with voters.
Method #3: Phone Banking
How It Works
You call a list of voters from a script — reminding them to vote, sharing information about upcoming elections, or identifying supporters. Phone banks can be run from campaign offices or from home using tools like ThruTalk or OpenVPB. Shifts are usually 2–3 hours.
Effectiveness
Research here is more nuanced. Professional phone banks using paid callers show minimal effect on turnout. However, volunteer phone banks — where callers are genuine community members rather than paid workers — show stronger results, with some studies finding a 3+ percentage point turnout boost among contacted voters. The key variable is authenticity: voters can tell when a call feels scripted versus genuine.
The main limitation of phone banking is contact rate. Most calls go unanswered, and a significant share of people hang up quickly. This drives down the cost-effectiveness compared to postcards, which guarantee delivery to a physical address.
Time Commitment
Moderate. Typically involves 2–3 hour scheduled shifts, though many organizations now allow remote phone banking from home, which removes the commute burden. Emotionally, it can be draining — rejection via telephone is frequent.
Accessibility
Good for remote participation, but requires scheduled availability and the ability to handle repeated rejection gracefully. Not ideal for people with phone anxiety or who dislike scripted conversations.
Cost
Very low for volunteers. Campaigns provide the calling lists and scripts; volunteers just need a phone and a quiet space.
Best For
Volunteers who are comfortable on the phone, good at improvising within a script, and want to maximize contact in a short time window — especially in the final days before an election when delivery timelines for mail have passed.
Method #4: Text Banking
How It Works
Using peer-to-peer texting platforms like Hustle or ThruText, volunteers send personalized text messages to voters — usually with a brief GOTV message and a link to voting information. Unlike automated mass texts, peer-to-peer texting involves a real volunteer sending each message, which is a legal and ethical requirement.
Effectiveness
Text banking is faster than phone banking and reaches more people per hour, but effectiveness data is more mixed than for postcards or canvassing. Contact rates are higher than phone calls (people read texts more reliably than they answer unknown calls), but the interaction is brief and easy to ignore. Most studies suggest a modest positive effect on turnout, roughly comparable to professional direct mail.
Time Commitment
Moderate to low. Texting shifts can be done from anywhere with a phone, and some platforms allow fully asynchronous work — you respond to replies on your own schedule.
Accessibility
High. Text banking works from anywhere, requires no travel, and doesn't involve real-time verbal communication. It's a good option for volunteers who want to contribute digitally without the commitment of a phone bank shift.
Cost
Very low for volunteers.
Best For
Digitally-native volunteers who prefer asynchronous work, or campaigns looking to reach younger voters who are less likely to answer unknown calls but do engage with texts.

Which Method Is Right for You?
Choose postcards if: You want maximum flexibility, prefer not to engage in real-time conversations with strangers, and want a satisfying, tactile way to contribute. Especially good if you have an irregular schedule, limited mobility, or live far from campaign activity.
Choose door knocking if: You're a high-commitment volunteer, comfortable with face-to-face conversations, and want the highest possible impact per interaction. This is the most effective method — but also the most demanding.
Choose phone banking if: You're comfortable on the phone, can work scheduled shifts, and want to reach voters quickly — especially in the weeks and days immediately before an election when mail is no longer an option.
Choose text banking if: You want a fully digital, flexible option with no travel and no live conversations. Good as a secondary activity alongside postcards.
The best answer for most volunteers: combine methods. Write postcards for long-lead outreach starting 4–6 weeks before an election, then do a phone or text bank shift in the final week when every conversation counts. This multi-touch approach mirrors what the most effective GOTV campaigns do with professional resources — and volunteers can do it from their living rooms.
