If your onboarding isn't working, don't worry. Simply skip it altogether and just follow this doc.
First, Head to Newsletter Glue > Settings > Connections to connect your email service provider to WordPress. For more help with this, read: API integration - How do I connect my email service?
Then, scroll down and fill out the details there.
Finally, head over to the new post we created for you (or any other post), and scroll past your content to the advanced settings, where you should see this:
Look for the Send as newsletter toggle at the bottom left hand corner of the form and toggle it ON.
This will send your post to subscribers when you next publish or update your post.
And that's it! Now you know how to use Newsletter Glue. Happy sending!
And if something still isn't working, please feel free to contact us.
