The best way to contact your backers is to do a Project Update. you can do this by pressing the 'update backers' button on the right hand side of your dashboard. A project update goes out via email to all your backers and is a good way to let everyone know how your project is going. It will also be publicly visible to anyone visiting your project page via the 'updates' tab.


Or, you can message your backers during your project by clicking the 'message backers' button on the right hand side of your Crowdfunder dashboard. You can select individual backers to contact, or all of them. Your message will come from your Crowdfunder username and your email address will not be shown. 


Alternatively, once your project is has closed successfully, you’ll receive a list of your backer’s email addresses.
