Postcards to Voters (https://postcardstovoters.org/) is a program that gives you addresses to registered Democrats and Independents in districts where there are upcoming elections. They coordinate with campaigns to deliver targeted, handwritten messages to voters to help get out the voter or persuade them to vote for the Democrat running.
This is a really fun activity that you can do almost anytime. The website has a bunch of postcard templates that you can download and print, but I found Collective Vision: Postcards for Political Action (https://www.collectivevision.us/) as a great one-stop shop, where you can buy packs of postcards and stamps in one fell swoop.
So once you’ve got your postcards picked out or purchased you need to get your address lists from Postcards To Voters.
It only takes about 10 minutes in total to get up and running with this group.
Step 1: Fill out a registration in the Volunteer tab of the Postcards to Voters (https://postcardstovoters.org/) website.
Step 2: Wait. One of the volunteers will get back to you with instructions on how to get your first batch of addresses. It took about 2-3 days for them to first get back to me.
Step 3: Write a sample postcard and send picture back to them. There are a list of rules for how to write the postcard, but all are pretty straightforward. Once they are sure you’ve got it, you’ll get your first batch of addresses.
Each campaign is different, but they will provide you with all of the information regarding how to address the cards and what information must be included, etc. Then you drop them in the mail.
Once you are in the system they have an automated bot (Addy) who will provide you with more addresses on request.
The availability of addresses will depend on which campaigns have signed up to be part of the program. For example, right now the addresses are primarily for the Alabama Senate race and the Doug Jones campaign. The website has a lot of information on the history of the program and where it has been used.
