Tilly vs Yozo

Yozo sends messages: email, SMS and WhatsApp from one chat, with pop-ups, reviews and a support chat agent.

Pick Yozo if you want one app that sends on every channel and talks to your customers. Pick Tilly if you want to grow beyond messages. Tilly reads your product pages and reviews, writes your flows and campaigns into Klaviyo, blog posts onto your Shopify blog and Meta and Google ads, and fixes the pages that lose you sales. Nothing goes out without your approval, and every night it writes the next piece with what worked. Try the free audit: paste your store URL and see in about a minute what Tilly would fix first.

Yozo is one AI agent you chat with. Its Shopify listing describes it building campaigns, flows, pop-ups, reviews and a 24/7 support agent across email, WhatsApp and SMS. source, checked 25 September 2026

You describe what you want in the chat and Yozo builds it and sends it: it is the sender, so there is no separate email app to pay for. Its support agent answers shoppers on your site, Instagram, Messenger and WhatsApp, and it collects reviews and shows them on your store. Plans are priced by emails sent, from a free plan to 10,000 emails a month on Starter.

Each app’s cells come from its own Shopify listing or pricing page, linked beside the words. “Not listed” means we did not find it there, not that the app cannot do it. Tilly’s column is our own product.

Yozo's facts come from its Shopify App Store listing, because its own website renders in the browser and gave us nothing we could read and check. Each cell links to the listing and the date it was read.

Yozo's Shopify listing shows a free plan with its AI campaign and flow builder, then Starter at $50 a month, which includes 10,000 emails and $10 of WhatsApp and SMS message credits, and Growth at $150 a month with 200,000 emails. Sending is part of the price.

Tilly does not send, so its price covers only what it makes. After 100 free credits the Store plan is $49 a month for 500 credits: 30 for an email flow, 10 for a campaign, 15 for a blog post, 10 for a Meta ad batch plus 5 per ad image. A store using Tilly also pays its sender, which today needs to be Klaviyo for Tilly to publish directly.

For a small store that only needs email and SMS handled, Yozo's plan covers more for the money. For a store that already pays for Klaviyo and needs more than messaging, the comparison is Tilly's plan against the writing time it replaces.

The last table prices the same store on both. These apps do different jobs and price them differently, so the fair comparison is what each costs to try and to start paying. Ad spend, and a sender for any email, are billed separately.

This page is by Tilly, so Yozo's advantages come first. These are things it does that Tilly does not. source, checked 25 September 2026

• Yozo sends. Its plans include email volume and message credits for WhatsApp and SMS; Tilly sends nothing and needs Klaviyo behind it.
• WhatsApp and SMS campaigns and flows are built in; Tilly writes email only.
• It answers your customers: an AI chat agent on your site, Instagram, Messenger and WhatsApp. Tilly has no customer service side.
• It collects and embeds reviews itself, where Tilly reads the reviews you already have but does not gather them.

Tilly works beyond messaging. The same brand profile writes blog posts that publish to your Shopify blog, Meta ads published paused, and product-page fixes on a preview copy of your theme, as well as email flows and campaigns. Yozo's listing is about messaging, pop-ups, reviews and support.

It learns from your own results. Every night it reads what each email, ad, post and page change earned, keeps the patterns your numbers back up, and writes the next piece with them, so a winning ad angle can become an email subject line and a product-page headline. Yozo runs messages across channels; Tilly carries what worked in one channel into the writing for the others. (How the loop works.)

It also watches two things most marketing tools miss: whether AI assistants name your store when asked your buyers' questions, the part of search now called AEO (how to get named by ChatGPT), and every change made to your theme, products, pages and menus, with what each said before and after.

It decides what to write from who buys. The audit reads your storefront and reviews and builds personas with their pain points; each email is aimed at one persona and one worry, and the email calendar plans the next month around your markets' holidays and your own launches.

It keeps you in charge of every send. Tilly's flows land in Klaviyo as drafts and nothing goes out until you switch it on, which suits stores that want a person to read every email first.

It has a longer reach into results. Revenue from each flow and campaign is tied back to the persona and angle it was written for, and that feeds what Tilly suggests next.

Moving between the two depends on where you send. If Yozo is your sender and you move to Tilly, you would also move sending to Klaviyo: export contacts with their consent status for each channel, rebuild the flows, and warm up the new sender gradually.

WhatsApp and SMS subscribers need care. Consent for those channels is separate from email consent, so bring the records across exactly and do not message anyone on a channel they did not agree to.

If you keep Yozo for SMS, WhatsApp and support, and want Tilly for blog, ads and page work, the two do not overlap there. Only email would be written in two places, so decide which one owns it.

Either way, run Tilly's free audit first. It needs only your store address and shows the personas and a welcome flow, which is enough to judge the writing before changing anything.
