Postcards to Voters (PtV) motivates already-registered voters to vote in top-ticket, down-ballot, and special election campaigns. PtV is nimble and trusted by campaigns. They quickly get addresses and required messaging to postcard writers.
Visit Postcards to Voters, click the "Join or Rejoin" button to register. They will ask you to write a 4x6 piece of paper with a specified postcard-formatted message. You will photograph that with your phone and send it back to them. A Postcards to Voters staffer will respond and approve your access to addresses. (This may not be instant.)
When approved, visit instructions for retrieval of PtV addresses. There are two pathways to addresses: e-mail a "bot" following a certain format, or interact with the "bot" on message service Slack, which is very quick and easy once you set up the service on your computer or phone. For Slack use with PtV, set up Slack from the designated invitation link here.
When it's time to write cards you'll choose how many addresses (four or more) you'll write in any one batch - promising to complete the cards in that batch within 3 days.
