Tilly vs Omnisend

If you send through Omnisend and are happy with it, know this first: Tilly publishes emails into Klaviyo, not Omnisend, so an Omnisend store would copy them across by hand.

Stay with Omnisend if the sending and its ready-made workflows are what you need. Look at Tilly with Klaviyo if the problem is everything around the sending: knowing who buys, writing the flows and campaigns for them, and doing the same for your blog, ads and product pages. Tilly reads your product pages and reviews, writes for your real buyers, waits for your approval, and every night writes the next piece with what worked.

Omnisend is an email and SMS platform for online stores, rated 4.7 out of 5 on its Shopify listing. source, checked 25 September 2026

You start from ready-made welcome, abandoned cart and post-purchase workflows, and its AI writes on-brand copy and picks the products to recommend. It sends email, SMS, newsletters and web push; campaigns and segments can also be built from ChatGPT or Claude, and stores paying $400 a month or more get an account expert.

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.

The Omnisend column is read from Omnisend's pricing page and its Shopify App Store listing, cell by cell, with the page and date behind each figure. Tilly's column is our own configuration.

Omnisend prices by contacts, with a free plan up to 250 contacts and 500 emails a month. On its Shopify listing, Standard starts at $16 a month for up to 500 contacts and Pro at $59 for up to 2,500, both rising as the list grows; SMS is extra, from $0.007 a message. Omnisend also gives an account expert to anyone paying $400 a month or more.

Tilly does not price by contacts or sends. After 100 free credits, the Store plan is $49 a month for 500 credits and Growth is $149 for 2,000 credits across up to 3 stores. A flow costs 30 credits and a campaign 10; audits, previews and reports cost nothing. Because Tilly is not a sender, the fair comparison is with the time or agency spend that goes into writing your emails today, not with Omnisend's bill.

The last table prices the same store on both. Two emails a month to 250 people is 500 sends; a weekly email to 500 people is about 2,200. Flows send on top of campaigns, SMS costs extra on every app, and bigger lists cost more on all of them, so check each app’s own calculator for your exact figure. Yozo prices by emails sent; Klaviyo, Omnisend and Mailchimp by contacts; Enrich Labs and Tilly write for Klaviyo rather than send.

Here is what Omnisend does that Tilly does not. source, checked 25 September 2026

• Omnisend is a sender. Email, newsletters, SMS and web push go out from one account; Tilly sends nothing and needs a sender behind it.
• It ships ready-made welcome, abandoned cart and post-purchase automations that work the day you install it, with no writing step in between.
• Its record on Shopify is public: a 4.7 rating on the App Store when we checked, and 250+ integrations.
• Tilly cannot publish into Omnisend yet. For an Omnisend store that is the deciding point today, and it will stay one until that connection ships.

Tilly starts from your store rather than from a template. The free audit reads your storefront, products and reviews and builds personas with their pain points, and each email it writes answers one of those pains for one of those people. Omnisend's AI helps write copy and choose products for a campaign you have already decided to send; Tilly decides what is worth sending in the first place.

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. Omnisend reports on its own sends; Tilly carries what worked across email, ads and your store pages. (How the loop works.)

It looks past the usual channels too. It checks whether AI assistants recommend your store for your buyers' questions (getting recommended by ChatGPT), and it records each change made to your theme, products, pages and menus, before and after, every six hours.

It covers more than email. The same brand profile feeds an SEO agent that publishes posts to your Shopify blog, an ads agent that sends creative to Meta paused, and a CRO agent that puts page fixes on a preview copy of your theme. The personas and the claims stay consistent across all of them.

Results come back to the work. A campaign's revenue sits next to the persona and the angle it was written for, so the next month's plan builds on what actually worked.

It also plans. The email calendar agent lays out next month's campaigns around holidays in the countries you sell to and your own launches, with a reason for each slot, and the plan is free. Building the month is where the credits go.

Today there is no clean switch from Omnisend to Tilly, because Tilly does not publish to Omnisend. If you want Tilly's writing now, the choices are to paste its emails into Omnisend yourself, or to move sending to Klaviyo, which is a larger decision than this page should make for you.

If you do move senders, export contacts with their consent and suppression status, expect to rebuild each automation by hand, and warm the new sending domain gradually rather than mailing the whole list on day one. None of that is specific to Tilly; it is what any move between senders costs.

The low-risk path is to run Tilly's free audit, read the personas and the welcome flow it writes, and judge whether the writing is worth the wait for the Omnisend connection. The audit needs only your store address.
