Your co-worker has created a list of all the leads who have not visited your blog in the last 90 days. What should your company do with these leads?
Don’t bother trying to email them again. Remove them immediately from all send lists but keep them in your database.
Pass the list of leads over to sales so they can start calling them and selling your products/services.
Delete them. These leads are unengaged and probably won’t buy, so it’s not worth continuing to market to them.
Send them an email with your top performing blog posts to try and entice them to engage.
