I wouldn't advise you do it. You will just get banned by the affiliate network, and/or be held liable legally.
Firstly, it violates CAN-SPAM act. It may also violate other country's laws like GDPR, especially when you get their personal info (email address, in this case) without their permission.
In fact, some affiliate networks have gotten into trouble due to affiliates doing email blasts. I won't reveal much, but the company is called XMission. They're an ISP company but because their clients have received email spams, they have brought affiliate companies to court for violating CAN-SPAM act.
Secondly, your sender email address and domain name will just end up in spamhaus almost instantly if you blast emails to people who did not consent. Your future emails will all just end up in the SPAM folder or just get blocked automatically.
Lastly, cold emails have the worse conversion rates. Imagine receiving an email from a stranger telling you about an offer... Would you trust and buy it? Nope. If you're using Mailchimp or some email platforms your account will be flagged faster than you think, especially when the open rates are terrible. It also costs you money, unless if you do it with your own mail server.
Note: again, just my advice. You're free to your own actions. But just be careful. And you can still get some conversions from cold emails, but expect conversion rates to be as low as <0.1% even if the offer/LP is great..
