Hi rudya,

Since individual email messages can be created by the sender to use specific fonts, sizing, images, and formatting, the option to adjust the size of Dynamic Type may not work for all incoming messages. For example, while a standard written communication from a friend or colleague may support the larger setting for text size, a specially formatted marketing email message from a company may not.

If you'd like to see the text on such emails, it may be possible to zoom into them by pinching out with two fingers, or to rotate your iPhone into landscape mode.

Alternatively, you may benefit from the Accessibility feature known as Zoom. This feature can be turned on or off, and has a number of options and different ways it can be used to zoom in on the portion of the screen you're reading.

Let us know if this guide helps, or if you've got any questions:

Take care!
