Writers collaborating with and cross-promoting one another have been the key to discovery on the internet since its inception, notably in the blogosphere, where writers’ blogrolls helped unearth niche communities and build bonds of trust between writers.
The Substack network is deeply influenced by that ethos. Some of the most powerful ways to grow your Substack are the human-powered tools we’ve built that help writers suggest other writers to their readers via the subscribe flow, on their home pages and profiles, and in their emails.
None of these tools require the writer to be marketing-savvy, and none rely on clickbait or gimmicky packaging, but writers are using them to drive 40% of all free subscriptions and 12% of paid subscriptions across the Substack network.
Check out this summary of Substack’s writer collaboration tools, or keep reading to dive deeper:
Any writer, on or off Substack, can be added as the guest author of a post. Now, you can simply click the “+” sign under the post title and search for the name of any writer on Substack. If the writer isn’t on Substack yet, enter their email to send them a guest post invite.
The guest byline will display prominently at the top of the post, shining a spotlight on them so that readers can learn about their work and easily subscribe to their publication. Additionally, the post will be listed in their Substack profile.
Here are some guest collaborations we’ve spotted:

Host a Letter exchange
The most strategic approach for growing your publication is to work with other writers, podcasters, and publishers who have some audience overlap; for example, someone who writes on the same topic but has a different angle from your work, and thus a slightly different audience. One way to pitch a guest post with another writer is to suggest a letter exchange about a topic that intrigues you both.
Once you’ve agreed to do a letter exchange with another writer, here are the next steps to iron out.
Pick a topic. What question do you wish to address in the conversation? Picking a question where you might not agree with another writer can lead to more interesting conversations.
Name the series. The job of the series name, or title, is simple: to make people want to read your exchange. Think of your title as the hook to stop people in their busyness. A good title is brief. After you write it once, try chopping it in half again before you hit publish. For example,
Parker Molloy andtitled their exchange On Free Speech and Cancel Culture. Each exchange they hosted uses the title “On Free Speech and Cancel Culture” followed by the number of the letter.
Decide on a cadence. We recommend one letter per week from each writer; for example, one writer shares on Mondays and the other responds on Thursdays for three weeks. Agree on who will write the opening letter and who will have the last word.
Write your letters. To help readers understand the letter concept and orient themselves within the conversation, each title should include the letter number. Posts should include a short introduction and an embed of the preceding post in the conversation.
