Ask HN: Does anyone have a solution to 'listen' to newsletters?

I listen to a lot of podcasts and I subscribe to a lot of newsletters but honestly I do more of the former. I've been looking for a long time for a system where I maybe forward an email, and have it come back as a podcast in my feed.

I thought this was only me but one of my good friends is legally blind. He has a screen reader for his emails, but it's tied to his gmail and he can't carry it around with him. He also has the same problem and we had a long conversation about it last night.

There was a thing called HeraldSpeaks but it now 404s. Does anyone know anything else? Thanks in advance!
