I have a confusion about taking consent from a subject (affiliate & Partner). We are an organisation who search affiliate and partner on collected from internet and send the lead generation email to make them our affiliate and partner for the business. Taking consent before sending lead generation email is required in this case or we can send initial email (lead generation) keeping opt out option in email is enough.
If the “subject” is a individual (consumer) then you need the “opt in” consent before engaging them in marketing activities. If however by “subject” you refer to a representative of a company and is the company you are targeting with the advertising and not the individual than the “opt out” would be enough.
