Blogger is one of the oldest blogging platforms out there, and while it doesn't offer subscription or newsletter functionality itself it only takes a matter of minutes to hook up Buttondown so that every single Blogger page on your blog ends with a subscription form.

The key here is to use gadgets, which is Blogger's term for arbitrary widgets or pieces of functionality onto your core blog. You'll go through a few easy steps to add Buttondown's subscription forms to your Blogger site.

  • First, log into your Blogger account and navigate to the Layout section.
  • Click on Add a gadget and then HTML/Javascript. You'll get a popup prompting you to fill out a Title and Content; type in "Buttondown" in the Title page.
  • Next, head over to the Building your subscriber base documentation and scroll on down to the section titled ‌Embedding an HTML form. You'll see a code snippet starting with <form; copy that to your clipboard and paste it into the Content section in Blogger.
  • Hit Save and you're be good to go! You can now move that gadget to wherever you want in Blogger's layout. I'd recommend putting it in the footer so that folks can subscribe after finishing reading one of your blog posts.
