Yes, I know, draw.io theoretically isn’t entirely open source, but the source code is available and it can be self-hosted. Honestly, that’s good enough for me, I think I can make an exception for this one. But generally I care a lot about strictly using FOSS too. It can also be integrated with Nextcloud: https://apps.nextcloud.com/apps/drawio

Nothing about the program itself is subscription based. All of the normal features of an email client (that you would also find in Thunderbird) are available for free. You only need to pay if you want to use their services like Send later, read receipts or link tracking, because these requires backend servers and actually costs the money.
