When you’re growing a newsletter, there’s always something more urgent than listing it in directories: ads, lead magnets, referral programs, signup forms, cross-promotions. But directories are worth an afternoon. They’re free, they keep working long after you’ve submitted, and they put you in front of people actively looking for something new to read.

Newsletter directories are essentially lists or databases of newsletters organized into categories and niches to help people discover new newsletters they’d likely enjoy reading.

Listing your newsletter in the better directories gives you a small but steady source of new readers. Some also get you in front of sponsors and other newsletters looking for cross-promotions. Don’t expect much of an SEO boost, though: most directory links are marked so they don’t pass ranking value, and the readers are the real benefit.

What Info Will You Need?

Before adding your newsletter to any directories, you should create a simple document containing the main info you’ll need, including:

  • Email address
  • Newsletter name
  • Tag line
  • Description (create a few variations to avoid content duplication)
  • Topics
  • Landing page URL
  • Archive URL (optional)
  • Link to a sample issue (optional)
  • Email frequency
  • Language
  • Logo
  • Header image (various sizes are required including 3:2, 1:1, etc.)
  • Whether it’s free or paid
  • Number of subscribers
  • Open rate (bear in mind Apple Mail Privacy Protection inflates this, so click rate is the more honest number)
  • Click rate
  • Whether or not you’re interested in cross promotions and paid sponsors.

This may be a bit more info than you were expecting, but this is because a number of these directories also have features that help you to connect with other newsletters for cross-promotions. Potential sponsors often also browse these directories to find newsletters to run promotions in.

Delegating This Task

If you’re struggling to find the time to do this yourself, it’s a pretty simply task that can be delegated or outsourced easily. Whoever ends up adding your newsletter to these directories will need access to:

  • The document you created above.
  • The verification emails that most directories will require you to click before your listing goes live. They should not be using their own email address for this. They should be using your own company/newsletter email.

Be sure to request login details for all of the directories submitted to (where relevant), and links to the live listing so that you can check everything looks ok and is working correctly once your listing is live.
