Both the fundraiser organizer and the recipient can control email notifications, for themselves and for the other party.
If notifications are turned off, you won't receive email alerts when donations come in, but all donations will still appear in the Donations tab of your fundraiser dashboard.
If you're not receiving notifications and they appear to be enabled, check your spam folder. Notifications from GiveSendGo come from the @givesendgo.info domain. If you're still not seeing them, Contact Us and we'll take a look.
