Many matching gift programs require the donor to submit proof of their donation.
When you donate to charity: water, we immediately send you an email confirmation of your donation. Save this email as a PDF; it should suffice as proof of your donation.
To look back and find it, you can search your inbox for emails from firstname.lastname@example.org and the keywords “your donation is tax deductible." If you have any questions or your employer is requesting additional verification, please reach out to our Supporter Experience team at email@example.com.
