Tip for anyone with an email newsletter: please include a link to the post online, or a link to the newsletter sign-up page somewhere in the email. This makes it easy for people to link to your stuff so they can give you credit for the work you do.
@lmika I recently added a 'browser link to this email' in the signature to my weekly mailers (eg this weeks'). I will enlarge it.
However, I'm not crazy about driving so much traffic to a MailChimp domain I don't own and can't track (given boycott of Google Analytics). Are you aware of any affordable options with custom domain? Buttondown requires £25 prof. plan.
P.s. I think there's an opportunity for a mailer specifically designed with social sharing in mind (e.g. this, and optimised og tags etc.)
@warner Sorry, I actually don't have an email newsletter myself so I'm not sure I can offer any suggestions. I wrote this post as a reaction from wanting to share something from a newsletter I subscribed to, and I wanted to post a via link to the newsletter itself. There was nothing in the email (including the sender) that I could use and I had to do a web search to find the sign-up page.
I understand that it might not be possible in all circumstances, and I get not wanting to share a MailChimp domain. I've seen newsletter include a footer that says something like "if you want to share this newsletter, do this thing". I guess that would work if "this thing" is a link (or even just the URL in plain text) to the newsletter site, even if it's just the sign-up page. The newsletter in question didn't have anything like this, which drove me to write this post.
