BlueMail lets you adjust the text size independently for different parts of the app.
To change the font size, go to Settings | Global Settings | Customize Appearance | Text / Font Size, then select the area you want to adjust:
- Message List — font size in the email list.
- Folders List — font size in the folders/mailbox list.
- Compose — font size in the compose window.
- Email View — font size when reading an email.
Each can be set to: Small, Standard, Large, or Extra Large.
