Most of the users mainly face problems in setting a default mail account on their iOS devices and I was among them also. However, you should have multiple email accounts on your iPhone, iPad, or iPod touch and you want to send most of your emails through one mail account. Take a good view of the instructions on how to set a default mail account on iPhone, iPad or iPod touch:
1. Firstly, you have to launch settings from the device
2. Now you have to click Mail, Contacts, Calendars.
3. Now scroll down until you find the Default Account option, then simply tap on the Default Account option.
4. After step 3 the easiest part is to just select the account you want as primary.
That completes the procedure and I wish it removes any difficulty you might be having in the procedure. If you still have any issues feel free to ask us.
