The mini donation form may not correctly update to the phone type set in Administration > sites and settings.  It will keep the original phone type that was located within Administration > sites and settings at the time the part was created.  This is currently being evaluated by our developers and further information will be provided when it becomes available.  Creating  a new mini donation form part will allow you to have the part send out to the current email type within the Blackbaud Netcommunity admin > sites and settings section.
