Letterhead + Zapier
Edit in CMSZapier lets you connect Letterhead to thousands of other apps without writing code. Use it to automate audience management and content curation.
Connect your Letterhead account to Zapier
Section titled “Connect your Letterhead account to Zapier”- In Zapier, create a new Zap and search for Letterhead.
- When prompted, authenticate with a company-level API key. This connects Zapier to your entire company audience, not just a single newsletter. This may need to be enabled for your account — contact support. See Generate & manage API keys.
- Choose an action (below).
An older key scoped to a single newsletter won’t connect here, even if it still works elsewhere — if Zapier turns your key down, that’s usually why, and an administrator can generate a company-level one in a moment.
Generating API keys is an admin task — if you don’t see the option, ask an organization administrator.
What you can do
Section titled “What you can do”Add or update contacts
Section titled “Add or update contacts”Keep your Letterhead audience in sync with another system — a CRM, a form tool, a spreadsheet.
- Set the other app as the trigger (e.g. “new form submission”).
- Add the Letterhead — Add or Update Contact action and map the email and any other fields.
Manage tags
Section titled “Manage tags”Add or remove a tag on a contact from any Zap — useful for marking signup sources or triggering automations that react to tags.
Type the tag name the way you’d write it. Letterhead stores tag names in lower case with spaces as hyphens, and matches what you type — so “VIP Member” finds the tag you see as “vip-member”.
Add articles to your Curations library
Section titled “Add articles to your Curations library”Pipe links from another source into Curations for newsletter use: trigger on the source (e.g. a new item in a feed) and add the Letterhead curation action, mapping the URL.
Map the details too, not just the link. Letterhead saves what your Zap sends rather than reading the page itself, so a step that maps only the URL files the article with no title, summary or image — map the title, excerpt, image, author, publication name and date from the app you’re pulling from, and the article lands ready to drop into a newsletter.
You can also choose which newsletters the article is for, and pick more than one, so a single step shares it across everything it suits. Leave that empty to add it to your company-wide library without tying it to any one newsletter.
Existing channel-level Zaps
Section titled “Existing channel-level Zaps”Existing Zaps built with older channel-specific Letterhead actions keep working without changes — they stay on the version they were built with, and nothing about them moves. New Zaps get the company-level actions above, which cover your whole audience rather than one newsletter at a time.
Good to know
Section titled “Good to know”- Zaps start somewhere else. Letterhead is what a Zap does — adding a contact, changing tags, saving an article — so the first step is always an event in another tool.
- New subscribers added via Zapier only receive proper signup confirmation if your channel’s public archive is active — see Managing Your Channel Settings.
- You can also trigger welcome letters via Zapier.
