To subscribe to or unsubscribe from any optional email subscriptions, click the gear icon at the top right corner of any Classmates page and select Account, then Email Subscriptions. Under each section, check or uncheck any of the boxes, then click Save.
You'll also find an Email Preferences link at the bottom of each email from us, with the exception of customary emails you're required to receive as a member.
Keep in mind that any changes you make may take up to 10 days to process, since some email is queued in advance. You'll still occasionally receive customary emails that directly affect you as a member.
