This article shows you how to connect your RSS feeds so your dynamic content flows into your Letterhead Curations library.
Letterhead gives you the flexibility to pull dynamic content into your Curations Library, where articles can be stored, reviewed, and inserted into your newsletters. You can populate your Curations Library via RSS Feeds, Browser Extension, curations API or manually via the curations page.
This article focuses specifically on how to add via RSS Feeds.
What is an RSS Feed?
RSS (Really Simple Syndication) is a standard web feed format used to distribute frequently updated content—such as news articles, blog posts—in a machine-readable format. By connecting a valid RSS feed to Letterhead, you can automatically ingest content into your Curations Library and prepare it for publishing.
Why Use RSS with Letterhead?
By linking your RSS feeds, you enable Letterhead to automatically retrieve and store content from your site or other sources, maintain an up-to-date curation workflow, and simplify newsletter production by surfacing fresh content regularly.
💡 Tip
For one-off URLs you want to use directly in a newsletter, use the URL block instead of adding a feed.
Important Guidelines Before Adding RSS Feeds
1. Validate Your Feed First
Use a free tool like RSS Feed Validator to ensure your feed is functioning properly. Usually if it passes this, it should work in Letterhead.
If you're using a feed from a third party (such as a news source or publishing partner), you’ll need to contact them if the feed fails validation.
2. Safelist Letterhead's Crawlers
To ensure uninterrupted access to our RSS feeds, please ensure that the following crawler's domain is safe-listed:
Safelist Domain: *.tryletterhead.com | letterhead.email | letterhead.ai
By safe-listing the mentioned domains, you enable our crawlers to efficiently access and retrieve content from your RSS feeds.
In addition to this, the Letterhead crawler is labeled "LetterheadCurationBot", and its user-agent is below:
Mozilla/5.0 (compatible; LetterheadCurationBot/1.0; +http://tryletterhead.com/bots)
