We frequently get customers calling to ask our address etc - all of this is in the confirmation email so we ask them to find it, but many cannot find it in their huge inboxes. It would be very useful to just have a button to resend confirmations - currently the only way I can resend is to cancel the appointment and rebook it.
Sometimes they make minor changes, like change of time or service and they like a new confirmation. Or sometimes we have missed a letter when typing their email adress, and we need to resend it.
sometime clients entered wrong emial address and they never get informed
