When potential attendees contact you for information about the event, you
should have a pre-planned way to respond to their request, for example,
answering their questions and asking for their contact information so that you
can continue to be in touch with them. Make a list of all potential attendees
with their contact information (phone number, email and postal addresses)
and mark whether they will attend the event and whether they wish to receive
more information about the topic or your organisation. Some people might
not be able to attend the event, but may want to be invited to future events.
