Everyone likes Birthday emails. You collect each customers’ date of birth, then send marketing emails to them or their friends just before each birthday, to wish them a happy birthday and make more sales.
So what’s the problem? A little thing called COPPA:
the COPPA Rule came into effect in 1998 when [the US] Congress first passed the Children’s Online Privacy Protection Act. The Rule requires that operators of websites or online services directed to or knowingly used by children under the age of 13 years follow a number of special steps aimed at protecting children’s privacy, specifically around how children’s “personal information” (name, address, email, etc.) is handled … Some scholars argue, for instance, that the Rule has had a number of unintended consequences, including closing off vast swaths of the Internet from younger children, as banning users under the age of 13 can be perceived as easier and more cost effective than attempting to tackle COPPA compliance
Do you really want to get involved in more compliance work than you need? Then make sure you never collect anyone’s date of birth, even if that means you don’t send birthday emails.
