Does a tournament send match reminders or score alerts?

No. Tournaments do not send match reminders or score alerts by text. When a captain registers, they get an email with their team page. The public tournament page shows the bracket as you enter results, so teams and families can check it from their phones. To reach captains, use the captain emails in the Teams table. A newsletter started from Campaigns can also reach people by email, but only contacts who opted in to marketing.
