That’s a good place to start when defining a bad email list, but some CRMs like HubSpot and email providers like MailChimp go further, asking questions to make sure every contact uploaded is legitimate:
Does everybody on this list have a prior relationship with your business?
Do you have an unsubscribe list?
Did you purchase, rent, or lease the list from a third party?
Will the people on the list be expecting (not surprised by) your email?
Have you emailed these contacts within the last 12 months?
Most of these are self-explanatory but the first one bears repeating: Get rid of the list if you don't have a prior relationship with the contacts. If the recipient doesn’t have a prior relationship with you and isn’t expecting your email they’ll mark it as SPAM. This is not only discourteous, but can hurt the sender score of the servers you send from and make it harder for you to get your messages delivered.
These questions are asked when lists are uploaded; they’re not asked when a lead comes into the database by way of conversion through a form, since it’s assumed these folks want to stay connected by the action they took. It’s far better to build your list this way—organically, using remarkable content to drive traffic to your site and inspire contacts to opt-in to receive future emails and other business-related communication.

How to Improve/Update Your List
Over time, your email lists will slowly die or diminish in usefulness as contacts switch jobs, change email providers, or unsubscribe from your list —research says this will affect up to 25% of the contacts on your list each and every year. Re-engagement campaigns are one way to attack this problem.
Re-engagement campaigns are a systematic way to reawaken inactive subscribers and identify the email addresses in your database that should be removed. Re-engagement focuses on stale contacts— those who’ve been on your list for a long time, who aren’t opening, reading, or clicking on your emails, and lets you know whom to retain and whom to let go. Basically, through this process you’ll segment your lists based on contact usage metrics and design an email with a well-crafted offer designed to bring them back into the fold. Then you’ll study open and click-through rates over the next couple of days to make an informed decision based on the results. (10)
