You have people on your email list(s) who have never hired you, hired you and fired you, or hired you one time ages ago and you’ve never heard from them since.
They are dead weight—just taking up space.
Keep them on your list.
They are useful, because one day they may realize they need help, find one of your emails and contact you.
Email is cheap. Don’t delete anyone. They are useful, even if their usefulness isn’t presently clear.
Even if they never hire you (again), they might forward your link to someone who does hire you, or who forwards that link to someone else who does. They may tell someone about your upcoming webinar, your book, or your article, or share something you’ve said or done.
Keep everyone. Old clients, prospects, leads, and business contacts who couldn’t pick you out of a lineup.
And, unless you have very large lists, I wouldn’t bother sending out a “Click here if you want to continue receiving email from me” message, or reminding anyone they can unsubscribe.
Keep everyone. Because anyone may become your next client or lead them to you.
Are there exceptions? Subscribers you might want to delete?
If someone is a complete jerk and you never want to work with them or hear from them again, you might think about sending them to digital hell.
Think twice.
They may be idiots, but they are still useful.
They may never realize they are the problem, apologize, and change their ways, but they can still send you referrals. And traffic that turns into new business. Unless they’re completely in your face and making you miserable, keep them on your list. Forever.
Besides, if you delete them, what’s keeping them from signing up again with a new email (and IP address)?
Jerks do that, you know. Just to mess with you.
Don’t worry your pretty little head about the jerks and the idiots. Don’t try to figure them out, don’t engage them.
Ignore them and go do some work.
