“Your email subscribers may not know about your most popular articles and blog posts. Show them what you have to offer. You could even use automation to welcome new readers by sending them an exclusive guide or whitepaper when they sign up for your newsletter.”
Send subscribers your most popular social media posts on a weekly or monthly basis. For example, try sending your most outstanding Instagram images for the week/month in one email, then send another (at a later date) that’s all about your best tweets.
