IPhone – Can you set custom ringtones for contact groups

May I suggest our unique "MailShot Pro" app, which is the ONLY app on the store that lets you create contact groups in your address book that you can use from any app to send email, just as you would use a single contact.

We have tens of thousands of users using it for exactly the sort of thing you describe

• You can protect privacy by adding the contact group to the Bcc line.
• You can edit the group permanently in the MailShot app, or temporarily just before you send an email (simply by saving and retrieving the email from Drafts)
• And you can share groups between multiple devices using iCloud contact sharing.

Full Disclosure:I am the developer of MailShot and will benefit from its sale, but so might you :)

Hope this may help you somehow. Download Bento for Mac from here. Unfortunately, it's not supported by FileMaker anymore, but anyway it works fine even on El Capitan (I use it here :)) Open it and it will ask permission to access your Contacts. Allow it. This it will open very convenient interface for mass editing your Contacts in list and/or individually with ability to add your own fields. Cheers.
