Substack Tracking

We are now automatically assigning Substack emails to individual campaigns and organizations. You can also filter the feed for content sent via Substack. There is a growing trend among campaigns (particularly Democrats) to use Substack to send updates. They even include donation links in these. Because you are sending on Substack's domain instead of your own, the deliverability is likely higher and can be an important way to reach your supporters. This can be particularly helpful for Republican campaigns as we face unfair inboxing bias.
