You're worried about the wrong thing.

Estimated annual deaths due to air pollution in the USA: 27,700 in 2008, reducing to 19,800 in 2017, likely due to improvements in vehicle emissions.

Estimated deaths due to wifi: zero.

Radio waves are EM waves, like visible light, except that the photons have far lower energies. Whereas UV has *higher* energies than visible light, and hence can cause cell damage - skin cancer deaths are also substantial.

One square metre of ground receives around 1kW (1000 watts) of solar energy in the middle of a sunny day. A wifi antenna typically transmits 10mW (0.01 watts) intermittently.

So there you have it. Move to the country for clean air; cover yourself with suncream; but enjoy your wifi.

There must have been a few people killed by falling wifi access points or something crazy!

I'm doomed anyway! for many years I've worked around some *very* large radio transmitter kit at all sorts of frequencies and some crazy power levels... Nothing like that warm fuzzy feeling on a roof top surrounded by dishes and the like.

According to the complaints team;

It's not marketing spam - its a service update....

"I am sorry for any inconvenience caused by this email. I have checked your account and this is marked as opted out of marketing, but the email that you are referring to, this is classed as a service update and not a marketing email. We will send any emails that are classed as service updates, even if you have opted out of marketing. In the footer at the bottom of your email it does explain this, I will include this below for you, as we send this to try to help you to improve your service connection:

“You’re receiving this email because we want to help you to get the best coverage possible from your broadband connection.”"

I wonder what the ICO will say - so if you have been annoyed or got several of these messages and feel aggrieved then the reporting form for the ICO can be found here.

If they're advertising or selling anything, it is marketing.

Indeed where as Zen are just doubling down with every response...

"Thank you for your email and for taking the time to bring your concerns to our attention.

In this case, we consider the message we sent to you to be a service message. We regularly receive queries from our customers enquiring as to how they could improve their WiFi connection and found that many aren’t aware of options that were available to them to boost their connection. We’ve also carried out research within our customer base which confirmed our initial findings. In making our customers aware of these options, our intention is to give them more choice over their connection and ultimately provide them with a better service.

I can confirm that you are opted out of marketing and so won’t receive marketing communications from us.

Please be assured we take our Data Protection responsibilities seriously and take every effort to ensure that we strike a balance between contacting people who we think may genuinely want to hear from us and respecting individuals’ privacy.

I hope this answers your query."

Disappointing but not terribly surprising :-\

Cheers for posting the follow-up!
