An email agent that builds and publishes your flows
Tilly's email agent is an AI email marketing tool for Shopify that plans and writes your Klaviyo flows and campaigns (welcome, abandoned cart, post-purchase, winback and more), with every email written for one customer persona from your brand audit. It does not send email itself: each flow is created in Klaviyo as a draft once you approve it, and Klaviyo does the sending.
Most Shopify stores know they should have more flows live. What stops them is the work: planning the timing, writing every email, designing it, building it in Klaviyo and checking it works. The email agent does all of it and waits for your approval. More on how the flows and campaigns fit together in Shopify email marketing, and on setting up the Klaviyo Shopify app first.
The flows it builds
It also writes one-off campaigns, usually from a slot in your email calendar. Still choosing a sender? Compare Shopify Email with the other email marketing apps for Shopify.

How it builds a flow
1. Reads your brand profile. Voice, look, offers, rules and personas.
2. Chooses who the flow is for. A welcome flow for a cautious first-timer answers different worries than one for a gift buyer.
3. Plans the flow. Number of emails, timing, and conditions like "skip if they already ordered".
4. Writes every email. Subject line, preview text and body, each email answering one objection, in the language your store sells in.
5. Checks claims. Against your category's rules and your own brand rules.
6. Renders it. You see the real email on desktop and mobile, with your logo, colours and products.
7. Publishes on approval. Once you approve, the flow goes into Klaviyo as a draft. Nothing sends until you switch it on in Klaviyo.
Every email knows who it is for
Each email card tells you the persona and the question it answers: "For the cautious first-timer. Answers: will this irritate my skin?" When results come in, they are tracked the same way, so you learn which worry, answered which way, earns the most.
What you see after it goes live
Revenue, orders, clicks and unsubscribes for each email, attached to the email itself. When one email carries the flow, Tilly drafts a variant of the weakest one and suggests a test.
Where it fits
The email agent writes. The email calendar decides when campaigns go out. The experiments agent tests subject lines, content and timing. All three read the same brand profile. For the other agents and how they hand work to each other, see marketing agents for Shopify.
What it does not do
- It does not send email or SMS. Klaviyo is required: Tilly writes into Klaviyo and Klaviyo sends. Omnisend and Shopify Email are not supported yet.
- It does not switch anything on by itself. Flows and campaigns go to Klaviyo as drafts after you approve them, and existing flows are left alone.
- It does not invent offers. A discount is only written in when the code exists in your store.
- Publishing needs a paid plan. On the Free plan you can build and preview a flow; sending it to Klaviyo starts on the Sales Starter plan. See pricing.
Questions people ask
Which email platforms does it publish to?
Klaviyo today. Omnisend and Shopify Email are next.
Will it overwrite my existing flows?
No. New flows go into Klaviyo as drafts once you approve them, and only go live when you switch them on there. Existing flows are left alone. Tilly will point out gaps and overlaps.
How much does a flow cost?
A full flow costs 30 credits and a single campaign costs 10. Previews, results and your own edits are free; asking Tilly to revise an email from a note is 3 credits.
Can I edit the emails?
Yes. Edit any line in place before you approve. Your edits also teach the brand profile about your voice.
