We use Substack for PreSeed Now. It's a twice-weekly email newsletter which unearths and profiles early stage B2B and DeepTech startups who are actively raising investment. It has some really cool features, particularly around intelligently trying to grow your paid subscriber base within the software. Drawbacks are that it doesn't play nice with other apps. It's hard / impossible for me to integrate it into anything else we use such as Notion, Hubspot, etc. and the stats are limited, so it's frustrating. I do get that this is partly due to them wanting to keep users focused on growing high quality newsletters, but it does leave little room to grow if you're adding extra products to your suite.
