If you have users who are to take part in Fleetcoach training but don't have an email address then a simple option to consider is establishing a new Gmail account and then using multiple aliases for your users.
Using email address aliases means your Gmail account will receive email sent to [email protected].
To send Fleetcoach invitations to these users simply use the [email protected] format for the email addresses in the Fleetcoach 'Invite users' form.
When the email is received at [email protected] you can distinguish which Fleetcoach invitation email is for which user by looking at the 'To:' field of the message. This will contain the full email alias used in the message (e.g., [email protected]).
Using this method you need only create one new email address that can be used for all your users who don't have an email address of their own.
Step one: Set up a gmail account, e.g., [email protected]
Step two: Send Fleetcoach invites as normal, to e.g., [email protected]
Step three: The [email protected] email address will receive all the emails.
