Companies Using Attentive

I read marketing tools through their switching data, and SMS is a category where switching is easy to misread. Our October 2026 crawl finds Attentive live on 13,145 domains, 5,888 of them matched to a company. A domain counts when a page loads Attentive's tag from cdn.attn.tv or sets the objects that tag creates, such as __attentive. That tag runs the sign-up unit that collects phone numbers and emails, so a hit means a brand collecting subscribers on its site today. When I loaded the 50 sites in the table on 10 October, 35 loaded the tag. I couldn't confirm the other 15, mostly because a bot wall or a country redirect blocked the check.

Two leaders, two kinds of store

Attentive is 2nd of 10 in SMS Marketing with 35.81%, behind Postscript's 17,227 domains (46.93%). The headline makes them sound like rivals for the same merchant. Mostly they aren't. Shopify runs on 16,987 of the 17,004 live domains where we detect Postscript, and on 59.48% of Attentive's. Postscript's base is close to all Shopify stores. Attentive's list adds department stores, big-box chains, hotels and restaurants: Target, Dillard's, Tractor Supply, Finish Line, Wyndham Hotels & Resorts and TGI Fridays all load its tag.

Sales signal: qualify the platform before you pitch. A Postscript domain is a Shopify store almost by definition. An Attentive domain may be a Shopify brand or a retailer with its own engineering team, and anything that installs as a Shopify app only fits the first.

Growth, and how much of it is ours

The chart reads 10,260 domains in June 2026, 11,893 in July, 12,185 in August, 12,648 in September and 13,145 in October. The June to July step of 1,633 reflects changes on our side, both the domains we cover and the signals we detect Attentive with, and the set of domains we crawl turns over every month as dead sites drop out and new ones are added. After July the line kept rising, by 1,252 domains in three months. Postscript, read from the same crawl, went from 18,034 to 17,227 over those months.

Exits are real too. 3,303 domains dropped Attentive between 16 March 2026, when we began tracking removals, and October, about one for every four domains live today. 356 of them still run it on another hostname, so the number of sites that left Attentive completely is closer to 2,950.

"Attentive and Postscript sit in the same category, yet nearly every Postscript site runs Shopify and four in ten Attentive sites don't." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: date your list. A domain that has kept Attentive since June has made a decision, while one added in the last 90 days may still be on a trial, which Attentive offers on request.

Who the customers are

39.69% of matched companies with a known size have 1 to 10 employees and 33.23% have 11 to 50. The age data fits a direct-to-consumer base: 44.55% were founded in the 2010s and only 9% in the 2020s. The other end is substantial. 211 companies have more than 1,000 staff, and the names are big: Target, Under Armour, Dillard's, Tiffany & Co. and Sears. Some run Attentive on one property, such as J.Crew on its Factory store, Simon Property Group on ShopSimon and Callaway on its Odyssey putter site. Attentive's about page shows Reebok among its customers and cites Steve Madden as a case study; both load the tag in our crawl.

Sales signal: at a large retailer, find the retention or CRM team that owns the subscriber list. That team picked Attentive and will judge anything that adds to, cleans or uses that list.

A narrow map, and a wide menu

The United States has 4,757 matched companies, the United Kingdom 369, Canada 209 and Australia 144. Those four hold 98.45% of the companies in our top 15 countries. By industry, Retail (17.52%) and Retail Apparel and Fashion (12.63%) lead, and Wellness and Fitness Services is third at 7.39%, with direct-selling brands such as AdvoCare and Juice Plus+. Restaurants don't show in the top ten industries, but they are easy to find in the list: TGI Fridays, Tropical Smoothie Cafe and MOD Pizza all load the tag.

Sales signal: outside the US only the UK list has any volume, about one British company for every 13 American ones. For UK agencies that is a short, well-qualified list of brands already paying for SMS.

What the switching table really shows

The largest row in is 360 domains that dropped Yotpo SMSBump and kept Attentive. The context: Yotpo said in August 2025 that it would close its SMS and email product at the end of December 2025, and named Attentive its primary strategic partner in its FAQ. Our SMSBump count fell from 11,899 domains in August 2026 to 3,613 in September and 625 in October as leftover tags came off. But 347 of the 360 already ran Attentive more than two weeks before SMSBump's tag disappeared. Whatever move they made happened before our window; the row records the cleanup.

The largest row out works the same way. 1,245 domains dropped Attentive and run Klaviyo. 189 of them still run Attentive on another hostname. Of the 1,056 that left entirely, 1,015 already had Klaviyo before they left, and our Klaviyo signal can't tell email from SMS, so we can't say how many moved their texting. What we can say is that those leavers carry Klaviyo less often (35.82%) than live Attentive domains do (49.06%). Postscript is small in both directions, 118 in and 68 out, and in most of those rows the site ran both tools before dropping one.

"Most of Attentive's switching rows are sites that ran two messaging tools and removed one. The SMSBump row is mostly old tags coming off, months after Yotpo closed the product." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: the 625 domains still showing SMSBump's tag in October are worth a check, because that tag belongs to a product Yotpo has closed. For anyone selling against Attentive, the 49.06% Klaviyo overlap means the usual account already pays Klaviyo, so the pitch is consolidation.

The stack around it

In our stack table, Shopify runs on 59.48% of live Attentive domains, Apple Pay on 53.72%, Shop Pay on 52.16% and PayPal on 52.04%. Klaviyo Reviews (35.33%) and Yotpo Reviews (17.04%) lead reviews. The ad tags point to real media budgets: DoubleClick Floodlight on 38.64%, Microsoft Advertising 37.59%, Pinterest 36.56%, The Trade Desk 12.25% and LiveIntent 11.85%. Fraud tools turn up as well: 282 domains run both Attentive and Signifyd. Omnisend, Yotpo's other named partner, is on 1.83%.

Sales signal: Floodlight and The Trade Desk usually mean an agency or in-house team buying programmatic display. Retail-media and identity vendors will find buyers here who already pay for audience data.

What it costs

Attentive doesn't list prices. Its pricing page, checked on 10 October 2026, says pricing is usage-based and set by list size and messages sent, with pay per message on text-only plans, discounts for bundling channels or AI products, and free trials on request. The bundles cover SMS, email, RCS and push.

Sales signal: when the bill grows with the list and the send volume, list quality is a cost line. Tools that clean or segment a subscriber list have a direct argument with Attentive customers.

Key takeaways

1. 13,145 live domains, 2nd in SMS Marketing with 35.81%.

2. A different base from Postscript: Shopify on 59.48% of Attentive domains, against 16,987 of Postscript's 17,004.

3. Small brands in the middle, and 211 matched companies above 1,000 staff.

4. 3,303 domains dropped it since March. The SMSBump and Klaviyo rows are mostly co-installed sites, not fresh switches.

5. Klaviyo on 49.06% of domains: Attentive runs next to it on about half its sites.
