# Design and approve first. Certify inboxes where you already do.

Litmus is typically an email rendering and QA platform. Teams searching for a Litmus alternative may want the work before screenshots: design, brand, review, and a structural check. Memo is that studio. Rendering labs stay the place you certify inboxes if you use one.

## When Memo fits

- The gap is production, not another screenshot grid. You need a studio to design and approve the email.
- Memo Check should catch broken links, missing alt, and structural issues before you pay for client previews.
- Brand Kits and review links belong in the same place the email is built.
- You will still export HTML into the sender, and you can still run inbox QA in the tool you already trust.

## When to stay with Litmus

- You already have a finished HTML file and only need inbox rendering, spam tests, or client previews.
- Design and approval already live in a studio, and you are only shopping for a QA lab.

## How it works

1. **Build the email in Memo** - Design with Brand Kits and reusable blocks so the file is email, not a graphic.
2. **Collect approval on a version** - Share a review link and record sign-off on the snapshot that will leave the studio.
3. **Run Memo Check** - Fix links, alt text, footer gaps, and structure before anyone opens a rendering lab.
4. **Export, then preview elsewhere** - Hand HTML to your sender. Use the QA platform you already trust if you need inbox screenshots.

## FAQ

### Is Memo a Litmus alternative?

Memo is an alternative for the production job: design, review, and preflight. It is not an inbox-rendering lab and does not certify clients.

### Does Memo Check replace rendering previews?

No. Memo Check is automated preflight on compiled HTML. Inbox screenshots and spam tests stay in a QA tool if you use one.

### Where does sending happen after Memo?

In the platform you already use. Memo creates the email and exports it. It does not send campaigns.

### Can we export and then run Litmus or another lab?

Yes. That is a common split: Memo for design and approval, a rendering lab for inbox certification.
