Not really. Email addresses that belong to an "opt in" list have opted to receive emails from, say, the list-purchasing company -- not your company. Even if the opt-in process includes language like, "Opt in to receive information from us, or offers from other companies we think you might enjoy," the fact is the recipient doesn't recall having a prior relationship with you, specifically. This makes it highly likely for the recipients to mark you as "spam" when you arrive in their inboxes. Hey, if they don't recognize you or remember opting in to communications from you ... can you blame them?

A tracking pixel is a snippet of code that allows you to track your subscribers’ activity across various channels like your website, landing pages, and newsletters. Then, you also have the option to send emails triggered by certain behaviors. So for example, if a subscriber goes to your site and checks out your product page, a tracking pixel can send an email with a special offer for the specific product the viewed.
