Getting an E-mail list of people checked in

If you've upgraded to the 4.3 version, there is a new Customer E-mail list function under Reports, with optional filtering.  Also on the tab views like On Site you can right-click, go to "Print for all shown reservations", and then "Customer E-mail list".

If you have not upgraded, you can still get a list of E-mail addresses for people checked in.  On the On Site tab view, simply click on Options and enable the E-mail field so the E-mail is shown.

Now you can use that list of E-mails a couple ways -- one way would be to simply copy them out of that list into your E-mail program, assuming it can handle a list of with one E-mail per line.  Highlight that whole column (click on the first E-mail address and drag down until all are selected), then Ctrl-C to copy, and then do whatever you need to do to get them into your other program.

You could also export the list to a "CSV" file that you can probably import into your E-mail program.
