What else should I do? The list is double opt-in, every message includes a one-click unsubscribe link, full contact info for the organization is included, and I send text-only.
One click unsubscription is presumably what they want.
My experience is that every unsubscribe goes to a form w/ a submit button. Shitty ones make you type your email address. (Mine doesn't.)
No idea if this holds if/when the email crawler bots start executing JS on crawl.
Just did a bit of unsubscribing and sydneytools.com.au, abc.net.au, squabblr.co, bundlehunt.com, and healingstreams.tv all one click unsubscribe.
