Cold Email Outreach
If you were bulk mailing random emails about consumer products, then yes, this would be SPAM and would be illegal in most countries.
However, cold email outreach is completely legal if you follow the rules.
The main difference is you are contacting businesses rather than consumers.
You must have a valid reason for getting in touch. You must target a specific person and job role in the organisation about something related to their work that provides value.
It must be about genuine commercial transactions without any tricks or deception and complete transparency about who you are.
Cold emails like this are legal in the majority of English-speaking countries around the world.
