I have ~200 subscribers and I want to send plain-text newsletters to them. No link/open-email tracking, no advanced features. Back to basics. I want to pay at most 5$/m for this.<p>Also, I'd like a trivially simple approach to sending a newsletter. Ideally, just send the main body of a newsletter to a dedicated email. A newsletter service would listen on this address, fill in my predefined email template with this body and send it to the subscribers.<p>I'm looking at MailChimp, Grip, SendGrid, but they are either expensive, cumbersome to use or doesn't support my use-case with free tiers.<p>Please tell me that something like this exists.
