Newsletter Glue is a newsletter plugin for WordPress. The plugin allows you to send a newsletter right from the WordPress editor (Gutenberg). After installing and activating the plugin, you will have a new option within the Gutenberg editor whether you want to send your content as a newsletter — other than blog post. But first, you need to connect Newsletter Glue with an email marketing service before you can send a newsletter. Newsletter Glue itself can be connected with ActiveCampaign, AWeber, Campaign Monitor, GetResponse, Klaviyo, Mailchimp, MailerLite, MailetJet, Moosend, SendGrid, Sendinblue, and Sendy.

Since the email creation is done via Gutenberg, you can add any Gutenberg block to your email. Be it the default blocks or blocks from third-party plugins such as Stackable and CoBlocks. Newsletter Glue itself also comes with a set of blocks as follows:

Of course, you can also use the blocks on blog posts if you don’t want to send your content as a newsletter. If you want to hide a certain content type (e.g., image gallery) from blog post, yet want to display it on the newsletter version, you can use the show/hide content block.

With Newsletter Glue, you can release your content into two versions: blog post and newsletter. Unfortunately, Newsletter Glue has no built-in analytics feature to allow you to track the performance your content after it being released. Also, you still need to login to the email marketing service you use to manage your email subscribers.

Newsletter Glue comes with features like premade newsletter templates and ability to personalize newsletters.
