New Feature Alert: Sponsor Inventory
While you’re attracting eyes to your newsletter on CrossLetter, why not tell potential sponsors about the options available in your newsletter?
We’ve added the opportunity to add sponsorship inventory to your newsletter!
Add sponsorship inventory in three simple steps:
Head over to your dashboard and select “Manage my Newsletter”
Scroll down to “Collaboration Options” and make sure that “Open to Sponsorship” is turned on
Click “Add Placement Type” under “Sponsorship Opportunities”, and pick from the drop-down options based on what you have available.
It’s that easy! You can add a description and pricing (choose your preferred currency), and once you update your newsletter, these will feature on your newsletter profile on CrossLetter!
It’s never been simpler to attract sponsors, and as we grow, we’ll be actively promoting newsletters on CrossLetter to help drive your email monetisation.

💡 Tip of the Week: Make your newsletter stand out to sponsors:
Keep your CrossLetter profile up to date with accurate subscriber numbers, open rates, and a clear description of your audience. Sponsors look for creators who know their readers well. The more complete your profile, the more likely you are to attract the right partnerships.
Head to the Sponsor section at crossletter.com to explore available opportunities and start building your sponsorship pipeline.
Let’s grow CrossLetter together!
The more newsletters to cross-promote with or sponsor, the better.
We’re just shy of 150 newsletters loaded, with tons more invites going out, but we’re constantly on the hunt to feature newsletters our users and fans want to see.

Your Newsletter Deserves to Grow
Growing a newsletter shouldn't mean fighting algorithms, draining ad budgets, or lighting smoke signals to reach potential subscribers.
We built CrossLetter because we believe the best way to grow is through genuine connections between creators and their audiences.
Every feature on the platform exists to make that process simpler, faster, and more rewarding.
We’ll be back in your inbox in 2 weeks, and so happy you’re here from the beginning.
Now, head on over to CrossLetter, explore what's possible, and start building something great.
