This function, Reports / Customer E-mail List, can be used to generate a list of customers with their E-mail lists. A similar Reservation E-mail list may also be invoked from right-click menus on many tab views (e.g. on the Arrivals tab view, right click and select Print for all shown reservations / Customer E-mail List).
As with the Customer Mailing Labels report, you can use the Reservation Filtering to select various criteria for which customers to be shown. Additional options are available to only show customers that have an E-mail address (or at least have an "@" symbol in the E-mail field), and also to exclude customers that have the Exclude from E-mail flag or the Warning flag set.
While Campground Master does not have a function built in to send mass mailings, this list can be exported to a CSV file for use in other programs to do the mass mailings. We recommend the software that we use for our own mailings -- GroupMail Plus, by Infacta. Go to http://www.infacta.com for more information. It can import the file created with the Export List button here.
PLEASE! -- Don't be tempted to just dump a list of E-mails into your Outlook address book and send everybody a message that way. For one thing, this is how viruses are usually spread ("worm" programs grab all of the E-mail addresses in your Outlook history and distribute spam and viruses to them), so it's not a risk you really want to expose to all of your customers. Worse yet, if you just use "cc" to send copies to them all, then every one of your customers will be able to see the address of all of your other customers -- a very inconsiderate practice, not to mention exposing them to thousands more potential virus-spreaders even if your own computer is perfectly safe.
