BusyCal and BusyContacts can send messages using Apple Mail and several other third-party mail clients.

BusyCal

BusyCal can send meeting invitations and email alarms through these email apps:

• Apple Mail
• Airmail
• Entourage
• MailMate
• MailPlane
• Outlook
• PostBox
• Sparrow
• Postbox

BusyCal requires AppleScript support for sending email attachments. These mail apps do no support AppleScript and, therefore, will not work with BusyCal:

• Gmail in a browser
• Mailbox
• Thunderbird
• Spark

BusyContacts

BusyContacts displays mail messages in the Activity List sent to/from the selected contact. Currently, only messages from Apple Mail or MailMate are supported.

In order to support third-party mail clients in BusyContacts, it requires work on the part of the mail vendor. Currently, only one third-party mail client, MailMate, has added support for BusyContacts. We hope more will support it in the future. Please contact your email vendor of choice and ask them to contact us for info on how to support BusyContacts.

If you are using a non-supported mail client, you may be able to work around this limitation by configuring both Apple Mail and your third-party mail app to sync with same mail accounts. Then BusyContacts will display the messages that have been downloaded to Apple Mail, which should be the same messages in your third-party mail client.
