You or your company page can now create a Newsletter on LinkedIn. This new feature will allow you to write about a professional topic you care about on a regular basis. All types of pages can create a newsletter, including Showcase Pages, Product Pages and Service Pages. You must meet the newsletter access criteria and be a super or content admin.
Once you create a newsletter, you can publish up to one article every 24 hours. Make your newsletter engaging by specifically addressing unique topics consistently enough that subscribers look forward to the next article.
By default, your page followers will be invited by notification to subscribe to your newsletter once the first article has been published. Members can subscribe and will then receive a notification and email every time you write a new article.
