## Removing Sources

To remove a source from your newsletter:

1. Navigate to the Sources tab
2. Find the source you want to remove
3. Click the "Remove" button next to the source

<Warning>
  Removing a source will not delete existing content that has already been delivered. It only stops monitoring future content from that source.
</Warning>

## Source Strategy Tips

### Diversify Your Mix

Balance different content types for richer newsletters:

```
Example: "Web Development Weekly"
- 2-3 YouTube channels (video tutorials, conference talks)
- 2-3 Subreddits (community discussions, questions)
- 2-3 X accounts (quick tips, breaking news)
```

### Quality Over Quantity

<Tip>
  Start with fewer high-quality sources rather than maxing out your limit. You can always add more later.
</Tip>

It's better to have 5 consistently valuable sources than 10 sources with mixed quality.

### Align Sources with Your Sections

Plan your sources based on the sections you want in your newsletter:

| Section                  | Matching Sources                           |
| ------------------------ | ------------------------------------------ |
| "Latest Research Papers" | Academic researchers on X, ArXiv subreddit |
| "Tutorial Videos"        | Educational YouTube channels               |
| "Community Discussions"  | Active subreddits in your niche            |
| "Breaking News"          | News-focused X accounts                    |

## Troubleshooting

### Source Not Found

If your search doesn't find a source:

* Double-check the spelling
* Try searching without special characters (@ or r/)
* Verify the account/channel exists on the platform
* For YouTube, make sure it's a channel, not a video

### Source Added But No Content

If a source appears but isn't generating content:

* The source may not have published new content since it was added
* Check the source's last post/upload date on the platform
* Wait for the next scheduled delivery to see fresh content

## Next Steps

After adding sources:

1. [Create sections](/newsletters/sections) - Define what content to extract with AI prompts
2. [Set your cadence](/newsletters/cadence) - Choose delivery frequency
