The last step is to follow up and evaluate your virtual fundraiser. Don't forget to thank your donors, volunteers, staff, and partners for their participation and generosity. Send them a personalized email, letter, or phone call, and include a receipt, a report, or a certificate of appreciation. Ask them for their feedback, suggestions, or testimonials, and use them to improve your future fundraisers. Analyze the data and metrics of your fundraiser, such as the number of attendees, donors, donations, shares, views, and comments. Compare them to your goals and expectations, and identify what worked well and what didn't. Celebrate your achievements and learn from your challenges.
