✦ Built for Shopify × Klaviyo

Email flows that sound like you, written in minutes, not weeks.

Clausi learns your voice from three quick questions, then generates complete email and SMS flows in under 60 seconds: industry-aware copy that sounds like you wrote it, A/B subject lines, and one-click push to Klaviyo, Mailchimp, or any webhook.

No credit card required · 3 free generations · Works alongside Klaviyo

Klaviyo builds the automation. Clausi writes the copy that goes inside it.

Email body
Hi {{ first_name | default: 'there' }}, Luminary exists because most skincare doesn't do what it says it does. We built formulas that do. Every product is dermatologist-tested, zero filler ingredients, backed by a 30-day money-back guarantee. If it doesn't work, full refund. No questions. Use WELCOME15 for 15% off your first order. Expires in 7 days. Shop the collection →

Your voice, learned

Three questions. Then every email sounds like you.

During setup, Clausi asks how you'd pitch a friend, describe your favorite product, and answer a frustrated customer. It reads how you write, not what you write, and builds a voice profile every flow follows. Typos welcome.

The two-minute voice interview

A friend texts you: "so what do you actually sell, and why is it good?"

haha ok so we roast coffee to order. you buy it, we roast it that morning, it ships same day. nothing sits in a warehouse. ever.

What Clausi just learned

Lowercase, quick, short bursts. Leads with the concrete fact, not the pitch.

Your voice profileBuilt in 2 min

Lowercase, quick, talks in short bursts. Leads with the concrete fact, not the pitch. Product talk is sensory and story-led ("more like blueberries", "we fought hard for that lot"). Owns mistakes fast and personally: "that's on us", then the fix, same sentence. Never corporate, never salesy, no exclamation points. Signs off like a person.

Customer Insights

Your orders know which flow to build next

Upload an orders CSV (parsed in your browser, your data never leaves your machine) or read from Klaviyo. Clausi finds your repeat rate and reorder gap, then recommends flows with timing from your own numbers.

Why Clausi

The copy problem, not the automation problem

Klaviyo is a great automation platform. It builds the sequences and manages the triggers. It just doesn't write the emails, and writing the emails is where all the time goes. That one thing is all Clausi does.

Industry-specific from the start

Pet care emails mention the pet by name. Apparel sends at 30 minutes. Supplement reminders go out on day 25. And if you're not one of the eight built-in verticals, describe what you sell and Clausi writes a custom brief for your exact niche.

Every flow. Fully written.

Not subject line suggestions. Not fill-in-the-blank templates. Complete email copy for every email in every flow, plus the HTML files, the send schedule, and the trigger logic to wire it live.

Timing from data, not guessing

Browse abandonment converts at 5.2% in the first hour, 2.1% at 24 hours. The price increase flow that doesn't exist in any other tool. Winback at 60 days, not 6 months.

SMS that won't get you sued

Flip one toggle and any flow generates as a text sequence instead. Opt-out language where the law requires it, quiet hours respected, one SMS segment, zero blast energy. Paste into Klaviyo SMS, Omnisend, or Postscript.

Industry-specific

Written for your category

Generic email tools write for everyone. Clausi writes for the category you're actually in, with industry benchmarks, timing rules, and copy patterns baked in.

Don't see your industry? Describe it.

Tell Clausi what you make and who buys it (hot sauce, dog grooming, pottery classes, anything) and it builds a custom copy brief for your exact niche: the relationship your customers have with you, the patterns that work, and your category's clichés to avoid. Every flow is written to it.

The flow no other tool has

Raising prices this year? Say it right.

Small business tariff costs tripled in the last year. Clausi's price increase flow writes the 3-email sequence that keeps customer trust. Transparent communication cuts backlash by 30%.

Who it's for

Built for founders who sell direct

Not agencies. Not enterprise. People who built something worth buying and need email copy that sounds like them, not like a marketing department.

🧪

The supplement founder

45-day creatine supply, 3 SKUs

Replenishment Flow

Customers loved the product but kept ghosting around day 40. Not churning, just forgetting to reorder until they ran out and bought whatever was on Amazon.

What helped: Replenishment flow timed to day 38.

Result: 38% repurchase lift in the first 60 days.
