What is a CMS, and does your shop need a separate one?
The part of your site where people change words, pictures and pages without a developer. Most shops already have one built into the platform, so the question is whether you've outgrown it.
- 019CMS (Content Management System)
- Software that allows users to create, manage, and modify website content. Integrating a CMS with email marketing platforms enables seamless content sharing and campaign management.

- Built in
- Shopify's theme editor, pages and blog, or WordPress behind a WooCommerce shop
- Separate ones
- Contentful, Sanity and Storyblok, usually in headless builds
- Doesn't own
- Prices, stock or the checkout, which stay with the ecommerce platform
- The test
- Can your marketing team publish a landing page this week without a developer?
Shopify already has a CMS, it just doesn't call it one
If you're on Shopify, you've already got one. The theme editor, pages, blog posts, menus and metaobjects, which hold structured content like size guides, all do a CMS's job. It's also where the words search engines read get written: page titles, descriptions and collection copy, the raw material of ecommerce SEO.
WooCommerce shops have it the other way round. WordPress is the CMS, and the shop is a plugin inside it. Either way, content and products sit in one admin, and that's worth more than it sounds when a campaign needs a page by Friday.
When a separate CMS starts paying for itself
A separate CMS usually turns up with a headless build, where the storefront is custom and the platform runs behind it. It earns its keep in a few places.
- Content is a product in itself: a magazine, a recipe library, guides people come back to
- You run several storefronts or languages from one set of content
- Several teams publish, and you need approval steps before anything goes live
The cost is a second system to pay for and keep alive, and a developer involved in every new page layout. If what you're really trying to fix is a slow theme, a new CMS won't do it.
Getting what's in your CMS into the inbox
Klaviyo can read a web feed, so a newsletter can pull in your latest posts without anyone copying and pasting. Handy if you publish a lot. For most shops, an automatic digest of every post becomes the email people learn to skip.
The better use is quieter. The guide that answers what customers keep asking, how to use it, how to care for it, belongs in a post purchase flow, sent the week it's needed. And if your posts get read but never sell, they usually need an ask, not more posts. We've written up why blog traffic doesn't convert.

FAQs

Is Shopify a CMS or an ecommerce platform?
Both, in practice. It's an ecommerce platform first, with content tools built in: the theme editor, pages, a blog, menus and metaobjects. That covers most direct to consumer shops. The ones that outgrow it usually do so on editorial volume or on running several storefronts, not on product pages.
Do we need a headless CMS?
Probably not yet. Headless separates the storefront from the platform, which buys design freedom and, done well, speed. It also puts a developer between your marketing team and every new layout. Worth it when content is the product or you run several sites. Not worth it to fix a slow theme.
Can our blog posts go out to the email list automatically?
Yes. Klaviyo can read a web feed from your blog and drop the latest posts into a template. Whether you should is another matter, because a digest of everything gets skimmed and ignored. Pick the one post that answers something customers actually ask, and write a proper email around it.
Rather we explained it on your own account?
