How long does it take after completing or purchasing the election until the voter invitations are sent?

If the start of the election is set to “Immediately”, the voter invitations are usually sent to the voters within 10–30 minutes. E-mail delivery can be delayed if the receiving server operates spam filters that prevent the delivery of e-mail from unknown sender addresses (greylisting). If this is the case, a new delivery attempt is made, which may exceed the delivery time of 30 minutes.
