How can I control how many emails group members receive?
Members can control their email settings individually.
As an organizer, each time you create a card, by default this is sent to members as an email. To choose to not send a card out as an email, simply un-check the “Send notifications” box in the lower left side of the card. Note: you can edit this card later and check the “notifications” option, to control when a card is sent out as an email.
