I had a crisis about this recently and maintain everything on Ghost for the emails that we send and want to be read on the web after: ghost.org/
We got too many subscribers before publishing again, so I'm going to try selfhosting because the platform was too expensive (after ~10k).
The major drawback for Ghost though is I can't segment our audience, so I don't know how long we're going to last with it.
Otherwise Mailchimp for everything else, and SendGrid connected to Django for sending verification/welcome emails from our product signup, etc.
