My understanding was that as long as you are sending marketing emails pertaining to the actual business eg. Party supplies and nothing else e.g. trips abroad for your partner companies then you were fine? This is as long as they can clearly ‘unsubscribe’ and they have consented to this already. The trick is finding out when consent was given..there’s a difference between consent being given 6 months ago and 6 years ago?
@EZA15 I think you're nearly right here. Emails (not marketing ones) about the service being provided does not need marketing consent - so a message about your purchase itself. Feedback requests are also not marketing (and yet I find these more annoying!). You may rely on the soft opt-in offered by PECR* to then send marketing material for the same sort of goods, as long as you offer 'unsubscribe' in the first and every email/text/electronic message. Your GDPR legal basis would probably be legitimate interests here.
I think! The relationship between DPA/GDPR and PECR is awfully convoluted!
By the way, there is no time limit to consent, so it doesn't really matter how long ago, but whether it was reasonable to continue indefinitely will depend on the circumstances. It does matter whether it meets up to GDPR standards. No need to refresh older ones if clearly indicated freely-given informed etc etc.
PECR is Privacy and Electronic Communication Regulation, due to be superseded by the E-Privacy Regulation which has now slipped to 2020, which is post-Brexit... so who knows what will happen with that.
Sorry to go on - it's helpful to me to try to make sure I have this straight!
