The newsletter editor also reflects styling from the Newsletter Theme Designer so that you can see exactly what your subscribers will see while you write your newsletter.

We'll be adding lots more functionality to this in the upcoming weeks and months, but wanted to get the basic features out to you as soon as possible. 

Callout card block is now renamed Container block. This better reflects its features. In addition, you can now toggle full width for container blocks, allowing you to create sections (not just callouts) in your newsletter.

You can add other blocks into this container which gives you more design options. Make any block full width by adding it into this container and toggling the full width option.

Major improvement - Closer integration between block editor and newsletters: It's now much easier to make small formatting changes in the block editor that will show up in newsletters. For example, alignment.

View online links now contain a hash as part of the URL for security: The hash is only valid for that specific post/newsletter. So if the hash is wrong or someone tried to change the post ID it won't work.

1.0.3 – Strip default CSS

New feature

Strip Newsletter Glue’s default CSS: This is a feature for advanced users who want to completely remove all our CSS from their emails and replace it with their own.


In-line CSS: We’ve rebuilt our plugin so that all CSS is inserted inline. There are many advantages, including: we use less code (loads faster, cleaner, less chance of clipping) and forwarded emails retain their styling.

Preview email in new tab: Next to “Send test email” you’ll now find a “Preview email” button. This lets you quickly preview emails in your browser, instead of sending a test email every time.

Add text alignment in Callout cards: You can now align text in the settings side bar.

Campaign Monitor users must select a list ID before sending an email: Blank ID lists now cause an error message and sending is disabled. Previously, we allowed users to send emails without selecting a list. Emails would then get stuck on the backend as Campaign Monitor requires a list in order to send.

bug fix

Bug fix for Mailchimp audiences: Previously only showed up to 10 audiences. We now show the maximum 1000 audiences.

Dec 3, 2020

1.0.2 – Double confirmation sending

New feature

Double confirmation: Send as newsletter checkbox. We’ve added a double confirmation when sending updated newsletters. Next to Your email is ready to publish notification, you’ll now see an additional checkbox.

Your workflow when publishing a new newsletter will remain the same. This new checkbox is automatically checked for you, but you can uncheck it.

However, your updating workflow is now improved. This new checkbox is un-checked for posts that are being updated. This solves the problem of saving an updated post and accidentally sending out a newsletter. Only check this box once you’re ready.

Subscriber forms: You can now add text beneath button

Subscriber forms: Added checkbox form field. Includes option to select additional list for checkbox. This is useful for GDPR, but can be used for other purposes.


Callout card: Added font color option.

Metadata: Read online is now automatically hidden from your blog, even if you’ve set the metadata block to show up in your blog.

Custom post types: Remove custom post types (CPTs) that are obviously not for posting content. Like oEmbeds, menus, custom CSS, custom fields, blocks, forms etc…

bug fix

Metadata block was not showing reading time. After refresh, metadata block would ‘break’ and say that it was showing unexpected or invalid content. This is now fixed.

Pro plugin activation: Activating the pro plugin when the free plugin is still activated no longer causes a fatal error. Now, activating one Newsletter Glue plugin simply deactivates the other.

Pro plugin activation: In the newsletter theme designer, some of your selected styles were reset to default when you upgrade. This is now fixed.

Yoast duplicator plugin: If a post was previously published then duplicated using the Yoast Duplicate Post plugin, its published status will also show up in the duplicated post. This is now fixed.

Mailchimp font CSS: Link colour chosen in newsletter theme designer not showing up in emails for Mailchimp.
