# Reddit and X for Newsletter Writers and Podcasters

> To grow a newsletter or podcast with Reddit, answer questions in communities about your subject, not in communities about newsletters or podcasting. Put the useful part of a specific issue or episode in the reply itself, say that you write or host it, and add the link only as optional further reading. Then judge the result by who opens later issues, not by clicks.

## A subscription is a different sale

Most Reddit marketing advice is written for products: someone asks which tool to use, a founder answers, the buyer pays once. A newsletter or podcast asks for a place in someone's inbox or queue every week. The click is cheap. The second and third issue are what count. A reader who signed up from a bare link has no reason to open the next one; a reader who got a full answer from you in a thread already knows how you think.

This page is for writers on Substack, beehiiv, Ghost and similar platforms, and for independent podcasters. If your show lives mainly on a YouTube channel, the page for [YouTube creators](https://agentagency.si/for/youtube-creators) fits better.

## Where readers and listeners ask

The obvious places are often closed to you. The description of r/podcasts calls it a place to discover, discuss and review shows, and says plainly that it is **not a place to promote your podcast**. r/Substack describes itself as a place to discuss Substack, its newsletters and the platform, with no self-promotion, and many of its threads are writers asking about the platform and growth. r/suggestmeapodcast exists for recommendation requests; read its current rules before you name your own show there.

Your readers are in the communities about your subject. A newsletter on local government belongs near city subreddits; a podcast about nursing belongs where working nurses talk. Our guide on [finding subreddits where people ask](https://agentagency.si/guides/find-subreddits-where-buyers-ask) covers the searches that turn these up.

**Kinds of community and what each allows**

| Community | Who is there | What you can do |
| --- | --- | --- |
| Recommendation hubs such as r/podcasts | Listeners looking for shows | Recommend other people's work. Its description rules out promoting your own show. |
| Platform communities such as r/Substack | Writers and Substack users | Talk craft and tools. No self-promotion, and few posters are looking for something to read. |
| Topic communities about your subject | The readers you want | Answer with substance, disclose, and link only where the rules allow. |
| Replies on X | Readers, writers and hosts in your niche | Reply to the take first. Link only when it adds to what you said. |

The questions are specific: a medicine history podcast that is not true crime, a finance newsletter that explains without pushing stock picks, whether a paid newsletter beats its free tier. Each names a gap your work may fill, and each has good answers that are not yours.

## Put the issue in the reply, not behind the link

The common mistake is the teaser: three lines that summarise an issue and point to it. It asks for the click before it has given anything. Write the reply so it is complete without the click.

- **Answer the exact question** with the part of your issue or episode that fits, rewritten for this thread.
- **Say who you are** in one plain line: "I write a newsletter about this."
- **One link, at the end, if the rules allow it**, to the one issue or episode that goes deeper.
- **Name other good sources.** It is what makes your own mention believable.
- **Do not reuse the reply.** Reddit's help page on [spam](https://web.archive.org/web/20260830042641/https://support.reddithelp.com/hc/en-us/articles/360043504051-Spam) lists mass-posting repetitive content for exposure as an example.

> **Illustrative example:** **Illustrative example.** Someone in a city subreddit asks how to appeal a property tax assessment. A local-government newsletter writer answers with the steps, the deadline that catches most people and the form the county uses, then adds: "Disclosure: I write a newsletter on our county's budget. Issue 41 walked through an appeal start to finish, if you want the long version."

## Formats that work for podcasts

Nobody presses play on an hour of audio without a reason tied to the thread. [The Podcast Host](https://www.thepodcasthost.com/promotion/reddit-for-podcasters/) suggests sharing something from inside the episode instead of the link: a guest's quote, one insight, or a question the episode explores. It also warns that Reddit feedback can be blunt, which is useful if you want to know what lands.

- **The guest quote.** The one line the community will argue about, with context. The episode is the source, not the point.
- **The question.** Ask what your next episode explores. The answers often improve the episode.

## Running an AMA with the moderators

An Ask Me Anything is the one format where your work is the topic, so it needs the community's agreement first. Advice for authors from [Penguin Random House](https://authornews.penguinrandomhouse.com/tips-for-a-successful-reddit-ama/) follows this order.

1. **Use the account first** Have an active account, and take part, for at least a month before you ask.
2. **Write to the moderators** They often verify who you are and say what fits their rules.
3. **Announce it a day or two ahead** Give the date, start time and time zone.
4. **Stay for the first 60 to 90 minutes** Answer as many questions as you can, candidly.
5. **Add links at the end** Edit the post to thank people and link your newsletter or show.

## Saying it is yours

Reddit's [rules](https://redditinc.com/policies/reddit-rules) ask people to take part authentically and not to mislead others about who they are. The FTC's [guidance for influencers](https://www.ftc.gov/business-guidance/resources/disclosures-101-social-media-influencers) says to disclose any financial, employment, personal or family tie, next to the recommendation rather than in a bio. Your own newsletter is the clearest tie there is.

Whoever runs the account decides the wording, and platform rules and the law expect material connections to be disclosed. Our post on [clear disclosure in a comment](https://agentagency.si/blog/clear-disclosure-in-a-comment) has short examples.

## Measure readers who stay

Sign-ups alone are the wrong number. Ask whether readers from a community open the third issue, or whether listeners come back for the next episode. Substack added a Growth Sources tab in September 2025 that breaks growth down by source, including external sites; other platforms have their own reports.

1. Give each community its own tagged link or landing page where your platform supports it.
2. After a month, compare how readers from each source open later issues.
3. Keep the communities whose readers stay; drop the ones that sign up and go quiet.

One Substack writer reports Reddit posts and comments still sending readers two years later. It can happen, but no one can promise it.

## Where an agent helps, and where it does not

The slow part is reading: finding the few threads a week, across a dozen topic communities, where your subject comes up. Agent Agency reads up to five public pages of your newsletter or show site and writes a Product DNA you approve. The agents find threads where people ask what you cover, and on Reddit they read each community's rules.

In Approve mode every reply waits for your OK, and mentions of your work come only when they answer the question, under a daily cap. An agent does not know your subject the way you do; the best replies use what you actually wrote or said. See [how it works](https://agentagency.si/how-it-works).

**Doing it yourself and with an agent**

| Task | On your own | With an agent |
| --- | --- | --- |
| Finding topic threads | Searching each community by hand | Found for you |
| Reading community rules | Once, then from memory | Read by the Reddit agent for each community |
| Writing the reply | From scratch each time | Drafted from your Product DNA; in Approve mode it waits for your OK |
| Mentioning your work | Your call | Your call in Approve mode, under a daily cap |

> **Note:** Reddit and X are live, and YouTube is in testing. Threads and Quora are planned with no date. The [platforms page](https://agentagency.si/platforms) has the current list.

## Questions

### Can I promote my newsletter on r/Substack?

Its description says no self-promotion, and many threads there come from writers asking about the platform, not from people looking for something to read. It is useful for questions about the platform itself. Your readers are in the communities about your subject, where you can answer questions and say that you write about them.

### Is it allowed to recommend my own podcast on Reddit?

Reddit's site-wide rules do not ban it, but they ask for authentic participation and no misleading others. r/podcasts says in its description that it is not a place to promote your podcast. Each community sets its own limits, so read the rules and disclose that the show is yours every time.

### Should I post my whole issue on Reddit?

No. Rewrite the part that answers the question so the reply stands on its own. Full issues posted across communities look like repeated content, and a thin summary with a link gives readers little reason to click.
