Broadcast email automation.

Targeted email campaigns separate from your nurture sequences — promos, announcements, seasonal offers. AI drafts, you approve, A/B tests baked in.

The Problem

Mailchimp is overkill. Sending from Gmail is amateur.

You have a list of past customers but no good way to send a broadcast — promotion, holiday hours, new service launch. Email Campaigns gives you React Email + Resend deliverability with AI drafting, brand kit styling, and A/B testing built in.

How It Works

From idea to send in under 10 minutes.

STEP 01Pick Your Segment

Filter from your customer list — past customers, this month's leads, a specific service category. Save segments to reuse.

STEP 02AI Drafts Subject + Body

Tell Claude what the campaign is about. It writes the subject line, headline, body copy, and CTA — in your voice using your brand kit.

STEP 03React Email Render

Beautiful, mobile-responsive email built on React Email components. Brand colors, logo, fonts — all pulled from your brand kit.

STEP 04A/B Subject Test

Send variant A to 10%, variant B to 10%. Winner auto-sends to the remaining 80% an hour later.

STEP 05Resend + Track

Resend handles delivery. Opens, clicks, unsubs all tracked. Hot openers can route into Speed to Lead automatically.
