To let your backers know how the project is going you can post an update. Updates are like your project's blog. You'll find a link to post an update in the creator tools menu to the left of your project page. You can notify all of your backers about the new post or you can limit the notifications to backers within certain reward tiers. Simply toggle the “Select Tiers” option on the “Post an update” page and choose which tiers you’d like to notify.

You can also talk to your backers through our messaging system. To send the same message to backers in a particular reward tier, use the 'Message All' option for that tier in your Backer Report, which you can access through the creator tools menu. You can also message backers that fall into the specific search filters within your backer report (including backers that have or have not responded to their survey, backers with dropped or errored pledges, backers whose rewards you've marked as "sent," etc.).
To message backers individually, just use the 'Send Message' link from the backer list or their backer card.
Backers expect to connect with you through Kickstarter, so it's best to use our tools for sending updates, messages, and asking for information. Avoid asking people to sign up for another service as it can be confusing for backers, and difficult to keep all your information in one place.
