Draw attention to certain sections of your email by formatting them. Tap the Aa at the top left of the virtual keyboard to reveal the formatting tools.
Select a word or block of text and tap any of these buttons to adjust the style of the text.
There are regular options like bold, italic, and underline, but there are also tools for aligning your text, indenting it, and changing the font or color.
These options are also available in the Notes app and can be enabled in the same way.
