Hey ​@Alida - Meltwater doesn’t track Substack as a specific source type, but it is included in our crawled content. However, since it’s a huge source with thousands of individual subdomains for every writer, we aren’t able to configure it to crawl everything. We also are not be able to crawl paywalled content on Substack. Do you have a specific Substack subdomain that you need to monitor? If so you, you can try adding site:”SUBDOMAIN.substack.com/” to your search (obviously, you would need to replace SUBDOMAIN with the specific author that you’re looking to cover).
