I’m disappointed with the functionality of Identities as those work only in webmail 7. I try to explain as it is a bit twisted.
I use exclusively email clients on my Apple devices and in Apple Mail for Mac it is possible to add to each email address an individual name, so the Runbox identities are irrelevant.
In Apple Mail for iOS devices it is possible to add only one name. To avoid confusions on recipient side I left the name field in my settings blank, so the recipient sees purely the email address.
I was expecting that Runbox Identities will go deeper into the mailing system and will decorate each sent email with the Identities names set in Runbox 7. Not true, only the emails sent from webmail have this feature.
I have no idea how it is the situation in Android, but maybe some improvement is possible to help Apple devices users… without pointing the finger to Apple.
