Cheap Energy Club email about either receiving emails OR deleting account, due to GDPR

infocom

Just got this email from the cheap energy club to do with updating the terms due to GDPR. The email says:"If you'd like to stop receiving emails from us (which means you'll need to delete your Cheap Energy Club account), log in to your account and click 'Leave Energy Club' at the bottom of the page."

So I found this a bit of a surprise. It implies I can no longer just unsubscribe from emails (not that I want to) and keep my account, but have to delete my actual account. Or if I dont delete the account I will receive emails?

It seems to me some sort of ploy to try to keep everyone receiving their emails??? Its a bit drastic to close the account so therefore keep receiving emails?

Why not just offer an opt out of emails?

Is it legal to be doing be doing this? Just seems a real bad way to try to keep everyones details on file for GDPR... threat of full account closure.

GDPR is not about that. I can easily agree to something so you keep my details on record but opt out of email.

P.S. I am not deleting the account and OK to receive emails, so its not about my preference. I just find this choice quite bad.
