By now, you should have already completed most of the work for your campaign. There is no need to revisit things that have not yet been completed. Rather, refocus on what has worked best in the first eight weeks. Remember that this is the final push and a very important part of the campaign.
Update and Thank you: Continue to update your supporters on your progress, and be as transparent as possible. Implement suggestions from your supporters.
Send thank you notes to supporters asking them to share the campaign link. Highlight notable campaign supporters. If you have gained more supporters, highlight them on your project page. Re-contact your supporters through your email list and tell them your story in a new way.
Expect positive results and more donations when you put the time and effort into repeating past fundraising steps.
