When you run into issues with the formatting in your newsletter, you can use the eraser tool in the toolbar to clear the formatting of your content.
The most common source of formatting issues is when content is copy/pasted in from an outside source. Programs like MS Word and Publisher carry over their own HTML styles that can interfere with the TinyLetter editor. If you’re in the habit of composing your content in another program, we recommend copy/pasting your content into TinyLetter as plain text and doing your formatting within our editor.
