Anyone that donates, supports, "likes" or comments on your page shows up in your activity feed. This helps show new visitors how others got involved and makes them move likely to do so as well.
Once your campaign is live you'll get emails to help direct you through the first few weeks of your campaign. You'll also get emails and push notifications when something new happens and an easy way to respond.
Every campaign page features Facebook connected supporters first because their involvement gets you the most social impressions. Better yet, key friend activity triggers emails to other friends on Fundly, alerting them of things like making a donation or starting a personal fundraiser.
There is no minimum amount to raise in order to keep your funds. Payments are processed quickly and can usually be withdrawn in 24-48 hours of the donation. Automatic transfers can also be configured to further speed things up.
