Companies Using Marsello

Marsello is the loyalty platform I'd expect to find in a shop with a till as well as a website, so I wanted to see what its web footprint shows. A domain counts here when a page loads a Marsello script (from app.marsello.com or any marsello.app address) or sets Marsello's exit-popup cookie. That test finds 1,951 live domains in our October 2026 crawl. Then I asked Marsello's own server what each store gets, and the answer cut the count to 845 live domains, 459 matched to a company, 15th of 51 in Loyalty & Rewards with 0.67%.

Installed is not the same as running

Every Marsello store loads a small script whose address names the store's account. On 15 October we requested all 1,685 distinct addresses. For 644 domains Marsello sent a working script. For 1,106 it sent an empty file, and a slower re-fetch of 40 gave the same result. The tags are still on those pages: all 16 empty-script stores that answered our homepage request carried the tag, and the four we watched in a browser loaded the empty file and nothing else from Marsello. Most of the tags sit on Marsello's older loader at app.marsello.com; the newer pos.marsello.app loader points each store at its own portal on marsello.app. We removed the 1,106 and kept 201 domains whose address we couldn't read.

The removed group looks like lapsed web programmes. 148 of the 1,106 (13.38%) ran another loyalty app, against 27 of the 644 working ones (4.19%). What we can't rule out is a retailer that switched the web widget off and still runs Marsello at the till.

Sales signal: for a rival, the removed stores are the better prospects. They still carry Marsello's tag but get nothing from it, and some already run another loyalty app.

One point on the chart

The chart shows only October's cleaned 845, because our monthly totals include the empty-script stores. Uncleaned, they read 1,547 in June 2026, 1,798 in July and 1,769 in October. The June to July step is mostly coverage: the domains we crawl turn over every month, with dead sites dropping out and new ones added, and our detection signals widen over time. 215 domains dropped Marsello on at least one hostname since we began tracking it on 16 March 2026, and 12 still run it on another.

"Marsello's tag is on 1,951 domains, but its own server sends nothing to 1,106 of them. Count the scripts that run and the base is less than half the size." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: treat Marsello's web base as about 850 storefronts and flat. A pitch built on its growth won't survive a look at the store list.

Who buys it

64.92% of matched companies with a known size have 1 to 10 employees and 26.49% have 11 to 50. Only 5 have more than 200. They're established: 47.34% were founded in the 2010s and only 7.98% in the 2020s, while 39 companies (20.74%) predate 2000. Big Ray's, an Anchorage store, dates to 1947. The largest names run a single shop on Marsello. Charles Darwin University uses it on its campus bookshop, Neal's Yard Remedies on its US store.

Sales signal: the buyer is the owner or manager of a small, established shop. They want one tool for points, email and SMS, and they'll listen to anything that saves them a monthly bill.

English-speaking, retail and food

The United States has 223 matched companies, then Australia (83), New Zealand (51), Canada (35) and the United Kingdom (22): together 414, 91.59% of the 452 with a known country. New Zealand ranks third. Retail and clothing labels cover 56.98% of matched companies with a known industry, and food and drink adds 10.17%, with Gelato Messina, Four Pillars Gin and Brick Lane Brewing among them.

Sales signal: Australia and New Zealand together hold 134 matched companies. A rival with support staff in those time zones has a practical edge.

Smile, Yotpo and the overlap

We publish no switching rows. Before the cut, Smile was the rival Marsello met most: 105 Marsello domains ran Smile, out of 136 ever seen with both. 93 of the 105 were stores where Marsello's script came back empty. On the cleaned 845, only 12 run Smile and 10 run LoyaltyLion. Yotpo Loyalty & Referrals and BON Loyalty each overlap on fewer than 10.

"When a Marsello store also ran Smile, Marsello's script was usually empty. That's a store that moved its web loyalty and never removed the old tag." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: for Smile, LoyaltyLion and the rest, Marsello's live base is mostly uncontested; the contested stores were the ones we removed. For Marsello, the 644 working installs are the base to protect.

The stack around it

Across the 845 domains, Shopify runs on 91.24% and Ecwid on 2.84%. Instafeed is on 23.55% and Judge.me on 22.13%. Email is crowded for a product that sells email: Klaviyo runs on 26.39% and Mailchimp on 16.45%. Square shows on 7.69% and Lightspeed eCom on 1.3%. Google Analytics is on 80%.

Sales signal: about a quarter of Marsello stores run Klaviyo beside a product that sells email. That's the overlap a Marsello rep would try to consolidate, and the one a Klaviyo rep would use against Marsello's add-on.

What merchants say

Marsello's Shopify App Store listing (15 October 2026) rates it 4.2 out of 5 from 162 reviews, with 127 five-star and 18 one-star. The listing dates the app to 29 May 2017, and two of the three reviews shown come from merchants with seven or eight years on it, which matches the older loader on so many stores. The most recent review, from 2 October 2026, complains of a $200 price rise to $525 a month and expiring SMS credits. That's one review, but price rises are also the most common complaint in the reviews we read (14 mentions).

Sales signal: price is the opening with long-tenured Marsello accounts. Lead with total monthly cost for loyalty plus email plus SMS.

What it costs

Marsello's pricing page (15 October 2026) lists Loyalty Launch from $60 a month per site and Loyalty Accelerate from $120, billed in USD, with each shop and each online store counted as a site. Marketing add-ons start at $15 per 1,000 customers and SMS at $0.028 per credit. Lightspeed users get custom pricing, and there's a 14-day free trial.
