How to Write an Email Design Brief Your Designer Can Build From

Most email design delays do not start in the design tool. They start in the brief. A designer receives a message that says “Black Friday email, make it pop, link to the sale,” and then spends the next two days asking questions someone could have answered in five minutes. Which products? What exactly is the offer? Who is it going to? Who approves it?

A good brief removes those questions before work begins. It does not need to be long. One page is enough if it covers the right things.

What a one-page email brief should include

Here is a format that works for most ecommerce campaigns:

1. Goal. One sentence on what the email should achieve, such as “drive first purchases from new subscribers” or “clear remaining winter stock.”
2. Audience. The segment or list it goes to, and anyone who should be excluded.
3. Send date and time. Including the time zone.
4. Offer and terms. The exact offer wording, the code if there is one, the end date and any exclusions.
5. Primary action. The one thing the reader should do, with the exact link.
6. Products. The products to feature, in order of priority, with links.
7. Must-include copy. Legal lines, shipping notes or anything that cannot change.
8. Tone. Two or three words, such as “warm, confident, no hype.”
9. References. One or two past emails that worked, and one to avoid.
10. Assets. Where the photos, logos and fonts live.
11. Platform. The email platform the design will be built in, such as Klaviyo or Mailchimp.
12. Approver and deadline. Who signs off, and when the final version is needed.

Twelve lines. A designer with this page can start the same day.

What to leave out

A brief is not the place to design the email. Avoid drawing the layout in words (“logo at the top, then a big image, then three products…”). That removes the designer’s judgment and usually produces a weaker email. Describe the outcome and the constraints, and let the layout follow.

Leave out long brand histories too. If the designer needs your brand guidelines, link to them once. Repeating them in every brief buries the information that is specific to this campaign.

Be specific about the offer

The most common cause of a second round of revisions is an offer that changed after the design was done. “20% off sitewide” becomes “20% off, excluding new arrivals,” which changes the headline, the button and the footer. Confirm the final offer and terms before the brief goes out. If the offer is not final, say so in the brief, so the designer can keep that area easy to change.

Give feedback in one place, once

Briefs prevent most problems, but scattered feedback causes the rest. When several people comment separately over email, chat and calls, the designer receives conflicting instructions and has to guess which one wins.

Collect feedback from everyone who needs to see the draft, resolve disagreements internally, and send one consolidated set of comments. Comment directly on the design where possible, pointing to the exact element that needs to change. “Make the button stand out more” is vague. “The button blends into the background on mobile; try the darker green” is something a designer can act on.

Let your tools carry part of the brief

Some of the brief can be filled in automatically. Platforms that connect to your store already know your products, prices and images. Design tools with shared brand settings already know your colors and fonts.

That is part of how Nexmail works. It connects to a Shopify store, pulls the brand’s logo, colors, fonts, voice and product catalog, and designs campaigns inside locked brand guardrails. Feedback happens in a Figma-style editor with comments on the design itself, and finished emails export as production-ready HTML for Klaviyo, Mailchimp, Omnisend or Constant Contact. For brands that want the brief to be the last thing they write, a white-glove email design service can take it from there.

A brief is a promise

A good brief is a small promise from the brand to the designer: this is what we want, this will not change, and this person will approve it by this date. Keep that promise and the design work moves faster, the revisions get smaller and the emails get better.
