You can start off by writing an email to your friends and family explaining why you started your mycharity: water campaign and sharing the link to your page. We’ve found that the more personal you are with your message, the more responsive people will be.
You can also easily share the link to your campaign page on social media such as Facebook and Twitter -- spread the word about your campaign early and often! Post your URL as your status, post a comment about your campaign on your friends' walls and tweet about your campaign regularly.
Also, don't be afraid to send a few follow-up emails to your family and friends -- they'll appreciate the reminder to donate to your campaign before it closes.
