This newsletter has been moved a few times this year. I started at Revue, where I automatically posted the editions on my blog. I then used a few editions of Mailpoet as a WordPress plugin, to eventually land at Newsletter Glue. First as a betatester and now as a cheerleader. Newsletter Glue lets you write and send newsletters from your WordPress blog. In addition to a newsletter, it becomes a blog post and the edition is searchable on the web. It works really nicely and the developers are open to improvements.
I had not heard of Newsletter Glue. I currently use Buttondown.Email, however I have been looking at other options.
