Brew is an AI email marketing platform built around a simple workflow: describe the email you want, review the generated campaign, edit it, test it, then send or schedule it. According to Brew’s own Campaigns documentation, campaigns are one-off sends used for newsletters, product announcements, promotions, event invites, and similar messages.

The important part is this: Brew can speed up campaign creation, but it does not remove the need for judgment. You still need a clear audience, a real offer, accurate claims, working links, and proper compliance basics.

1. Set Up Your Sending Domain First

Before you send a campaign, make sure your sending domain is verified. Brew’s domain verification guide explains that emails sent through Brew come from your own domain once verification is complete.

Brew recommends using a subdomain such as mail.yourdomain.com, updates.yourdomain.com, or news.yourdomain.com instead of your root domain. This helps keep your main domain more isolated if deliverability problems appear later.

You will also need to add DNS records for authentication. Brew lists DKIM and SPF as required, with DMARC recommended. This matters because mailbox providers increasingly expect authenticated mail. Google’s email sender guidelines also emphasize authentication, low spam rates, and easy unsubscribe options for senders.

2. Build or Import the Right Audience

A campaign is only useful if it goes to the right people. Brew lets you create saved audiences from your contacts, and its Create Audiences guide describes audiences as dynamic segments that update as contacts meet or stop meeting the filter criteria.

For example, you might create an audience for:

• Trial users who have not booked a demo
• Customers who clicked a previous launch email
• Subscribers who have not opened in 60 or 90 days
• Recent buyers who should receive a product update

If you are moving from another email platform, Brew supports CSV contact uploads. The CSV Upload documentation says the required column is Email, with recommended fields like first name and last name.

Do not use purchased lists. Brew’s Audience Hygiene guide says contacts should have explicitly opted in, and list quality directly affects deliverability.

3. Write a Specific Campaign Prompt

Brew works best when the prompt is clear. Its Prompt Guide recommends naming the goal, audience, tone, structure, and any brand assets you want used.

A weak prompt would be:

Create an email campaign for our product.

A stronger prompt would be:

Create a one-off product announcement email for existing customers. We are launching a new analytics dashboard. The audience is SaaS founders and marketing leads. Use a clear, practical tone. Include one CTA to try the dashboard. Keep the email concise, with a subject line, preview text, short intro, three feature bullets, and a final CTA.

That gives Brew enough direction to produce something closer to usable on the first pass.

4. Review the Generated Email on the Canvas

After you submit the prompt, Brew generates the email on its campaign canvas. From there, the Campaigns documentation says you can edit the email, create variants, send a test, send now, schedule, or export it to another email service provider.

Do not treat the first draft as finished. Check:

• Subject line accuracy
• Preview text
• CTA destination
• Product claims
• Pricing or offer details
• Spelling and formatting
• Mobile readability
• Footer and unsubscribe details
• Whether the message matches the audience’s actual stage

This is especially important if your campaign mentions dates, pricing, availability, integrations, or legal/compliance claims.

5. Create Variants Before You Decide

Brew can generate variants without deleting the original version. For example, you can ask for three subject line options, a shorter version, or a version aimed at a different segment.

Useful follow-up prompts include:

Create three subject line variations: one direct, one curiosity-driven, and one benefit-led.

Make this email shorter and more executive-friendly.

Create a second version for enterprise buyers, with less emphasis on speed and more emphasis on control, reporting, and adoption.

The goal is not to generate endless options. The goal is to compare a few realistic directions before sending.

6. Send a Test Email

Before sending to your audience, use Brew’s test-send option. Brew’s docs recommend sending a preview to yourself or a teammate so you can see how the email lands in the inbox.

Open the test email on desktop and mobile. Click every link. Read the email like a subscriber, not like the person who wrote it.

A good campaign should make the next step obvious. If the reader has to work to understand the offer, the email is not ready.

7. Send Now or Schedule

When the campaign is ready, Brew lets you send immediately or schedule it for later. At send time, you choose a saved audience, select a verified domain, review sender details, and confirm.

This is the moment to slow down. Make sure the audience is correct. Make sure the sender name is recognizable. Make sure replies go to a real monitored inbox, not a dead address. Brew’s domain guide specifically recommends using a real reply address instead of no-reply.

8. Stay Compliant

For commercial email in the United States, the FTC’s CAN-SPAM compliance guide lays out basic requirements, including accurate header information, non-deceptive subject lines, a clear way to opt out, and a valid physical postal address.

Brew can help with the email workflow, but compliance is still your responsibility. If your campaign is promotional, make sure it is honest, easy to unsubscribe from, and sent only to people you are allowed to contact.

Final Takeaway

Brew is useful when you already know what you want to say, who should receive it, and what action you want them to take. The tool can help you move from brief to designed email faster, but the quality still depends on the inputs: a clean audience, a specific prompt, accurate details, and careful review.

A practical Brew workflow looks like this:

Verify your domain. Import or segment your audience. Write a detailed prompt. Review the generated campaign. Create variants. Test the email. Confirm compliance. Then send or schedule.

That is how you use Brew well: not as a shortcut around strategy, but as a faster way to turn a clear campaign brief into a polished email.
