Different Sounds for Multiple Email Accounts

Yes. I have done so. Go to Settings>Notifications>Mail>Allow Notifications>On. Then select the account below and to Sounds. In the next screen tap sounds and you can choose the sound that you want to use for that account. Do the same for all email accounts.

I do not use different sounds for VIP's. I only use different sounds for the different email accounts. You can not have a different sound for VIP's and then have another sound for the individual email accounts themselves, as far as I know. If I turn off sounds for VIP alerts, my email accounts still use the different sounds for incoming mail.

Are you using Push in Settings>Mail, contacts, calendars>Fetch New Data>Push>On?

Great thank you - worked a treat
