I should probably have been a bit clearer... the following is of course just my opinion.
Consent has to be freely given. It can't be made a condition of a service or purchase if that service or purchase can be delivered or made without that consent being given. You can't, for example, require that customers sign up for your mailing list as a condition of buying a TV where that TV can easily be delivered without signing you up for the mailing list.
?Consent is presumed not to be freely given? if the performance of a contract, including the provision of a service, is dependent on the consent despite such consent not being necessary for such performance.? (a quote in the ICO guidelines from 'Recital 43', whatever that is)
Consequently you can't demand consent for things that BCA members don't need to have in order for BCA membership to be delivered.
The flip side of that is that you don't need to ask consent for those things that BCA members do have to have (such as transactional emails) or would legitimately expect to receive (non-marketing informational emails e.g. access issue emails).
The BCA should also (and does) have a privacy policy which explains what data is being processed and why. You don't have to agree to that privacy policy in a contractual way; either the processing is allowed and valid or it isn't (and is illegal). The BCA privacy policy can (by its own terms) be changed at any time.
The important detail in the Calor privacy policy (which they could also change at any time, I suspect) is that:
a) 'communications about Community fund activity' (i.e. transactional and informational communications under the Legal and Legitimate arguments) don't require consent, and
b) 'communications about Calor news and offers if a user has opted in' does require consent (because it is marketing).
We should not be sending unconsented marketing; everyone (well most people
) are agreed on that. The privacy policy can easily be changed to tweak the wording relating to emailing news to reflect the law (which is that you _can_ send news and information provided it is not marketing including furthering the aims and objectives of the BCA). We just need to make sure the newsletter doesn't contain marketing (or there is a 'censored' version).
We could have a consented mail list for campaigning emails, or just an 'uncensored' newsletter containing all sorts of political opinions
The point is that there is at least some good stuff we can send out, so we should do everything that we are allowed to to send it out!
