BlueMail offers a number of ways to achieve this:
- You can quick tap on the avatar / image of the sender from the mail list, and you will see the option to Add this contact.
- You can do the same from the mail view itself.
- You can long tap the sender (bold text) from the mail view and then Add to Contact option.
- Lastly, and again from mail view, you can tap More Details, long tap any contact and then Add to Contact option.
Note: When you add a contact we interface to the existing contacts application, and you usually get options to create a new contact or to update an existing one.
