Heartly vs Omnisend
Heartly wins on flash-sale focus and public discovery. Omnisend wins on email marketing depth for merchants with mature email programs.
What is Omnisend?
Omnisend is an email and SMS marketing platform for e-commerce stores. Flash sales show up as a template inside the Omnisend campaign editor — a scheduled email blast with a countdown timer embedded in the message body. The sale itself still runs as a discount code on the merchant's existing store page.
Heartly treats the flash sale as the product. Omnisend treats email as the product and flash sale as an email template. Merchants who want a flash sale platform pick Heartly. Merchants who want an email platform with flash sale email templates pick Omnisend.

What Heartly adds that Omnisend does not have
Heartly gives every flash sale a public URL that ChatGPT, Gemini, Perplexity, and Claude can crawl and cite. A shopper asking Perplexity for current fashion deals can discover a Heartly-powered sale. Omnisend flash sales live inside email inboxes only — there is no public deal directory and no AI-crawler optimization. If the email never lands in the inbox, the sale is invisible.
Real scarcity vs timer scarcity
Heartly reads live inventory from Shopify or WooCommerce and ends the sale when the last unit sells. The countdown timer counts down real seconds against real stock. Omnisend embeds a visual countdown inside the email template but the underlying sale is a regular discount code with unlimited uses. When a shopper sees the timer hit zero they still get the code to work. The urgency signal is fake.
AI Assistant and Autopilot vs manual campaigns
Heartly Pro recommends the next flash sale based on inventory signals, sales history, and category trends. Autopilot schedules the sale during the peak-conversion hour for the shop's timezone. Omnisend asks the merchant to design the campaign, pick the product, set the discount, and schedule the send. Omnisend has an AI copy writer for subject lines but no data-driven sale recommendation.
Both platforms — Shopify and WooCommerce
Omnisend supports both Shopify and WooCommerce, same as Heartly. This is the one feature-parity point that matters — both platforms are treated as first-class. The differentiation is the product category, not the platform support.
Pricing
Omnisend pricing scales with contact list size. Heartly flat rate is €29 to €99 per month regardless of contact count, catalog size, or traffic. Merchants who want email marketing keep Omnisend and add Heartly for the flash sale surface. The two are not mutually exclusive — many Heartly merchants also run email lists.
