While you're able to alter your settings at any time, there isn't currently a way to ensure that you receive all alerts at the same time daily. What you might consider, if you haven't already, is the possibility of creating a special folder for CBANC notifications within your normal email account. That way, you'll find them all in one place when you decide to check out the latest news from the network.
To tailor your emails so that you receive the ones your most interested in, see How do I tailor the emails I receive from CBANC?
We’d love to hear from you on how we can improve the emails that we send. Please send us a note at firstname.lastname@example.org.
