Update, for everyone who was NO DOUBT ON TENTERHOOKS WAITING TO HEAR WHAT I DID!
Following Cheryl Lynn Eaton's advice, I checked out MailPoet, which is a mailing system that works as a Wordpress plugin. My website runs on Wordpress, so I was intrigued!
And I dig it. Simple but powerful interface for making nice-looking emails. Control over everything since it's all in my Wordpress installation.
And outgoing emails are handled by MailPoet themselves -- for up to 2000 subscribers. Over that and I have to pay, but the increments seem manageable.
So yeah, subscribe to my revamped newsletter! http://gregpak.com/im-upgrading-my-email-newsletter-sign-up-today/ https://mastodon.social/media/2sHsDcdsffWUMTNmTBg
