What will Upscribe do for your newsletter?

Upscribe in 4 easy steps

1. Create your publication

Connect your email platform in 2-clicks and enable your publication so other newsletters can find and recommend you.

3. Activate your Upscribe widget

Easily customise your Upscribe widget to match your brand's look and feel. Then paste our code snippet onto your page. And that's it!

4. Track your performance

Get detailed insights into how much revenue you're earning from Upscribe and how many new subscribers you're sending/receiving from recommendations.

Works with all major ESPS:

Is Upscribe really free to use?
Plus icon

Yes! You can create a publication and be recommended for free across Upscribe and our recommendations network. It's also free to use Upscribe to recommend other newsletters (both free and paid).

For paid recommendations, SparkLoop withholds a 20% commission plus small processing fee on your monthly payouts.

Does Upscribe work with my email platform?
Plus icon

Upscribe works with nearly all "pro" newsletter platforms via a 2-click, no-code integration. For ESPs we don't yet support, please contact our support to learn about custom integration options (where a small amount of coding is required).

Unfortunately Upscribe is not compatible with beginner platforms like Substack, SendFox or Ghost (yet) — they don't yet have the necessary functionality and API to support advanced growth tools like SparkLoop.

Can I customise my Upscribe widget/where it appears?
Plus icon

Yes! You can fully customise your Upscribe widget and where it appears on your website.

How many newsletters can I recommend at once?
Plus icon

You can choose unlimited newsletters to recommend. Both free and paid. We will show up to five of them in your Upscribe widget at once, and automatically optimise which recommendations to show so you get the best results.

Can I see which subscribers came from which recommender in my ESP?
Plus icon

Yes! When a new subscriber is referred to your newsletter via Upscribe, we automatically store the ID of the recommending publication as a custom field in your ESP. So you can send them a custom welcome email or segment them however you please.

Can I invite other newsletters to recommend me? What if they use a different ESP?
Plus icon

Yes — you'll grow fastest via Upscribe when you invite other newsletters you already know to partner up with you and recommend each other. It doesn't matter if you're using different email platforms. As long as they're compatible with Upscribe, you can recommend to each other no problem!

Why is the quality of subscribers from Upscribe so high?
Plus icon

Upscribe has been in private development for months. Whereas other platforms like Substack rushed out their own recommendations networks with a focus on vanity metrics, Upscribe has several unique features which ensure that — unlike other recommendations tools — subscribers referred via Upscribe are super high quality.

On average, subscribers acquired via Upscribe are ~10-20% more likely to stay engaged than even organic subscribers!

How much can I earn using Upscribe to recommend paid publications?
Plus icon

For most newsletter operators, the earning potential of Upscribe is life-changing. With zero ongoing work needed.

Check out the quick calculator (above) to predict your potential earnings.

Can I export my data?
Plus icon

Yes! You can generate a full export from the dashboard anytime, no questions asked. We want you to use SparkLoop because it's the best growth platform for newsletters (2.3x better growth on average, to be precise) — not because we're holding you hostage!

How can I pay newsletters to recommend my publication in their Upscribe widgets?
Plus icon

This is incredibly easy to do — with a guaranteed ROI — via our Partner Program feature.
