Companies Using VWO Engage

I expected to write about a dead product. PushCrew became VWO Engage, then VWO and AB Tasty came together under the Wingify name, and the push tool is now Wingify Engage. Three names usually leave a trail of orphaned tags, and I assumed this would be another. Our October 2026 crawl counts a domain when a page loads a script from cdn.pushcrew.com or creates the command queue that script uses. That finds 681 live domains, 369 matched to a company, 12th of 39 in Push Notifications with a 0.43% share.

Is the script still doing anything?

An install's script address carries an account id, and the file behind that address holds the account's live settings, including a switch that turns the script off. We read it for every account we could see. The 579 domains with a readable id belong to 465 accounts. 451 of those accounts serve a working setup, 5 have been switched off and 9 return a 404 because the account is gone. In domains, that's 565 live and 14 dead, 2.42% of the 579. Then we opened 50 random domains in a browser on 15 October. On 31 the script ran and fetched its setup, and 14 of those showed the opt-in prompt within about ten seconds; the rest wait longer, use the browser's own prompt or wait for a button click. Five more kept the snippet but were too slow to render, 7 sat behind bot walls, 4 were down and 3 had removed it.

Sales signal: treat this as a live install base. These sites can still collect subscribers today, so a push vendor selling against VWO Engage is asking for a migration, not filling a gap.

Flat since July

The chart reads 598 in June, 682 in July, 683 in August, 684 in September and 681 in October. The June step is ours: the domains we crawl change every month as dead sites drop out and new ones come in, and our detection signals widen over time. After July the count moves by three domains. Since we started tracking it on 16 March 2026, 95 domains dropped it on at least one hostname, and 15 of them still run it elsewhere, so 80 left it completely. That's a slow leak on a base of 681, and no sign of new demand replacing it.

"Three names in, the PushCrew script still loads a working setup on 565 of the 579 domains where we can read the account. The tag works. The install base has been flat since July." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: size the market at about 680 domains and roughly 465 accounts. Don't pitch it internally as a growing segment.

Who the customers are

64.83% of matched companies with a known size have 1 to 10 staff and 22.67% have 11 to 50. Only 13 companies employ more than 200. Age is the sharper signal. 55.96% were founded in the 2010s and only 2 of 218 in the 2020s, 0.92%. On iZooto's profile, 13.62% of matched companies are from this decade, and on Pushly's 4.44%. The bigger names run Engage on one property. Queens Library uses it on its mobile-app page and Tegeta Motors on service bookings. Cell Marque, now a MilliporeSigma business, runs it under an account registered to Sigma-Aldrich.

Sales signal: the buyer is usually the owner or a one-person marketing team. Pitch something they can switch on without a developer.

Fleets and aliases

Domains overstate customers here. Market Technologies, the company behind VantagePoint AI's trading software, runs one account across 35 domains, 5.18% of the 676 in our stack sample: brand sites, seminar pages and TraderPlanet aliases such as traderchat.com, which redirects to traderplanet.com. A Swiss marketing consultancy has 17 domains on one account, and REWW and Thredbo have five each. Still, 422 of the 465 accounts sit on a single domain.

Sales signal: dedupe by account before you count. A 35-domain row is one buying decision.

Where and in what industries

The United States has 119 matched companies, then Brazil with 58, India 20, Australia and the United Kingdom 19 each, Turkey and Italy 14 each. Brazil's weight is unusual: Pushly's profile has 600 American companies and 65 British ones, and Brazil doesn't make its top 15. Turkey shows up in the stack too, through ShopPHP, a Turkish store builder on 1.63% of domains. Advertising Services leads industries at 16.22%. Several of the named sites sell courses: trading education from VantagePoint AI and Trend Signal, property investing from REWW, marketing coaching from Nabenhauer Consulting.

Sales signal: Brazilian small businesses and English-language course sellers are the two clusters worth a dedicated sequence. Both buy traffic and want it back.

Rivals and switching

There's no switching corridor to report. VWO Engage sites almost never run a second push tool: only 5 also run OneSignal, 4 run PushOwl, and none carry Pushly, PushEngage or iZooto. None of the 80 domains that dropped it entirely now runs any of the other 38 push tools we track. OneSignal's 47,794 domains are about 70 times VWO Engage's count, and Pushly (1,701), PushEngage (1,468) and iZooto (1,310) are roughly two to two and a half times its size.

"Almost nobody runs VWO Engage beside another push tool, and the sites that drop it don't show up on a rival. When it goes, push goes with it." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: for a rival, the opening is the account owner who has stopped looking at the dashboard. For Wingify, it's the testing customers who have never added push.

The stack around it

Across the 676 domains in our stack sample, WordPress runs on 58.88% and Elementor on 11.09%. Google Analytics is on 83.73%. The ad tags explain why push matters to these sites: DoubleClick Floodlight is on 24.85%, Twitter Ads on 10.21% and Microsoft Advertising on 5.03%. ClickFunnels (2.66%) and Unbounce (2.37%) mark funnel sellers. Consent tools are thin, with Complianz and CookieYes on 3.7% each.

Sales signal: WordPress plugin vendors and paid-media agencies fit this list better than Shopify app makers, since Shopify is on only 2.22%.

What it costs and which plan they're on

Wingify's pricing page lists Growth, Pro and Enterprise push plans with no public prices. Its billing help article says plans are priced by subscribers and uses Growth as the example: $99 a month for up to 10,000. Custom branding is a Pro feature, and 418 of the 451 live setups still show the "Powered by" badge. Cart-abandonment campaigns are Enterprise only, which sits oddly with a base where Shopify and WooCommerce together cover under 10% of domains.

Sales signal: most accounts look like entry-level or legacy plans. Price-led pitches have room here, and so do upgrade offers from Wingify itself.

Key takeaways

1. 681 live domains, 12th of 39, flat since July.

2. 565 of 579 readable domains load a working setup; 14 point at dead accounts.

3. Small, older companies: 64.83% have 1 to 10 staff and 0.92% were founded in the 2020s.

4. 465 accounts behind 579 domains, with one 35-domain trading-software fleet.

5. Almost no overlap with other push tools, and no visible destination for leavers.
