Your fundraiser is live. Nobody can give until people know about it, so the first two days are about telling the right people, one at a time.
Start with the people closest to you and to the person you're raising for. Send it one at a time, in Messenger or a text. A message that names the person does more than a link dropped in a group chat.
Money sent to the GCash or bank account on your page doesn't show there by itself. Open your fundraiser, tap Log a gift, and enter the amount. It takes a minute, and a page that shows support gets more support. See how to record gifts you received.
A short thank-you the same day is the easiest way to get a second share. People who gave are often the ones who pass it on.
Two or three sentences is enough: how the person you're raising for is doing, what the help has done, what's still needed. An update gives everyone a reason to share it again. See how to write a fundraiser update.
Once a few people have given, ask one group you belong to, like your church, school or office. A page that already shows support is easier to say yes to. For more ideas, read promoting your fundraiser.
That's normal on day one. First gifts usually come from the people closest to you, so send it to one more person today rather than posting it everywhere at once.
