To create or edit a ladder, go to the Ladders section of the People tab in the Start Organizing" menu at the top of the page. Next, choose a group you want to add a ladder for. If you want to make a new ladder, click the Add New Ladder button to get started adding a new ladder. Otherwise, click the manage button next to a ladder you want to edit, then the edit button on the next page to edit that ladder.
When you click to create a new ladder, you'll be given the option to start with a blank ladder or one of our templates. The templates are for an email welcome series and an email reactivation campaign, and if you a have mobile messaging partnership, additional options as well. They can all be further customized.
On the editing page, you can give your ladder a title (this is for your internal use only) as well as write internal notes about the ladder, explaining to your colleagues what this ladder does. Below, you can click to start creating new rungs, triggers, and steps and build your ladder if your ladder isn't published yet. If it is, you can't add or remove rungs or steps, but you can edit existing ones to add or change triggers or edit step details. Most step detail edits will apply to everyone in the ladder or everyone who matches trigger conditions going forward except for waits -- if an activist is already in a wait when you make an edit they will not receive a new wait time, but will rather proceed with the old one. Any new activist entering the wait will receive the updated wait time.
In the toolbox on the bottom, if your ladder is not published yet you can save your ladder as a draft or publish it, and if it has been published already you can save your changes.
If you're working on a large or complex ladder, you can click Copy Steps in the bottom left to copy certain Decision steps and its follow up action, wait, or randomizer steps from one part of a ladder and paste them at the end point of a different branch in the ladder.
