Hi there @rogner,
There isn’t an option to automatically convert your newsletter to a published blog post as it is sent out. However, there are a couple of options here you could consider.
First, every newsletter has a published link so it can be viewed directly in a browser. You could use this link to make a simple blog posts that provides a button or link to the version that can be viewed in the browser.
You can find this link at the top of any newsletter you’ve sent – it says “view in browser”. Click there to see the link in action.
You can also find it under MailPoet > Emails, on the newsletters tab, hover over any newsletter and click “Preview” to view it in a browser window – this link, in the browser’s URL field at the top of the browser window, is the link you want. You can then use that URL inside a blog post you create and write, as a link to click, to let non-subscribers view the newsletter directly.
Alternately, you could consider doing this process **in reverse** — that is, make a blog post, and then send out a newsletter about your blog post! You can use the “Post Notifications” style email in MailPoet to send out notifications like this automatically; so you can make a blog post with your information in it, and then a notice will go out to your subscribers announcing the new blog post.
You can embed the entirety of the blog post in your email blast, or you can provide an excerpt with a link to click through and read the post in full on your site instead.

Hope one of those will work for you!
