With the GDPR now governing all email correspondence across Europe, adding an opt-out option to your email template no longer cuts it. Under this act, you must have explicit consent from your contacts to send them emails. Explicit, in this case, means the checkbox a person must click to opt in to an email subscription isn't pre-checked when they see it on your website. And when you buy your email lists, the people on it haven't been given this option -- making you non-compliant with GDPR before you send your first email.
If rounds of split testing, segmentation, and resends still result in low engagement scores for some of your subscribers then don’t be afraid to clean your list.
