Tait asks is it allowed for companies to offer you no choice but to receive marketing if you choose to use the service? Or do they have to offer you an opt-out?
A useful guide on the website of lawyer Pinsent Masons says “the user must be provided with an opportunity to opt-out of their details being used for this method. The best way of achieving this is to include an opt-out tick box as a part of the data protection notice. Failing to opt-out alone is unlikely to constitute valid consent, and can indicate that consent has been given if a clear prominent message is provided in the data protection notice or otherwise, such as: ‘By submitting your details, you are indicating your consent to receiving marketing emails from us, unless you have ticked the box below to indicate your objection to receiving these messages’.”
This seems to suggest that companies should at least offer the chance to opt out in a “clear prominent” way. Regardless of legalities, offering an opt-out at the very least (in best cases, an opt-in) is what every good brand should do. It informs the consumer that you take their right to privacy seriously and can only be a good foundation for future relationships.
