Relying on people to organically land on your site can be frustrating. It’s kind of like looking for a gas station to fill a nearly empty tank with Google Maps or Waze on the fritz. Instead, use your email newsletter to direct people there. Invite them to view your content or provide them with an incentive to stop by your site. Make sure to use a strong call to action, like in this example from nonprofit Parkrun:
Make it scannable. Your subscribers are busy people who get a lot of email, so it's safe to assume you don't have their undivided attention. Instead of one long block, break up your content into short paragraphs. Include subheadings and images to guide readers through your email and make it easier to scan, and add a teaser to the top of your newsletter to tell subscribers what's in store. If you're sending a long article, consider inserting a "read more" link so people can get to the rest when it's convenient for them. Your subject line should be to-the-point and easy to digest, too. You might even want to a/b test subject lines to see which ones perform best.
