It could be that your email address needs to be unblocked by our notification sender, Blackbaud.

If messages are not going to Spam, please do the following: Send an email from your own email account to unblockme@blackbaud.com. Note “UnBlock Me” in the subject line. You should receive a confirmation email shortly thereafter.
