Companies Using OptinMonster

We detect OptinMonster on 21,418 domains, including United Airlines, Sutherland Global, Harvard Business School Publishing Corporation. A detection means the technology is present on that domain, which for large organisations is often a single storefront or subdomain rather than a company-wide deployment. Among domains we matched to a company with a resolved industry, the most common is Software Development (4.04%).

We detect 21,418 domains running OptinMonster across our monthly crawl of live business domains. Company data could be matched for 12,403 of them (57.9%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 2,834 domains carried a OptinMonster detection previously and no longer do.

OptinMonster holds 5.01% of the Popups & Lead Capture category, ranking #7. This is a share of the domains we detect running a platform in this category — not a share of all websites, and not a share of spending — so it is not directly comparable to figures published on other denominators.

The top alternatives to OptinMonster include Popup Maker (27.32% market share), POWR (12.52% market share), Privy (8.85% market share), Mailmunch (8.19% market share) — measured as a share of the domains we detect running a platform in this category.

United States leads with 6,734 matched OptinMonster domains, followed by United Kingdom (1,066), Australia (562), Canada (507), Netherlands (371). These are counts within the 12,403 domains we could match to a company record, not the full detected base.

50.18% of the 12,403 enriched companies employ 10 people or fewer, 28.81% employ 11-50 and 12.98% employ 51-200. About 6.5% employ more than 200 - the largest big-company share of any major tool in this category.

Among the OptinMonster domains we could match to a company with a known founding date, most were founded in the Pre-1980 (12.45%), followed by the 1980s (6.33%). That matched subset is drawn from 12,403 companies and is not representative of all 21,418 detected domains. This suggests OptinMonster is most popular among established companies.

The ideal OptinMonster customer is: Company Size: 1-10 employees, Location: US, UK, or Brazil, City: Atlanta, San Francisco, Chicago, Founded: 2010-2019, Company Age: ~5-15 years old — based on our analysis of 12,403 enriched companies at TechnologyChecker.io.

For established sites with consistent traffic, yes. We detect OptinMonster on 21,418 active domains, including United Airlines, Harvard Business School Publishing, the University of Texas and Aramex. Its A/B testing and exit-intent targeting are what justify the price over a free plugin, and half its companies employ more than ten people - the largest average customer in this category.

OptinMonster offers four plans billed annually: Basic at $9/month for one site, Plus at $19/month with A/B testing and analytics, Pro at $29/month adding exit-intent and multiple site support, and Growth at $49/month for ecommerce features and priority support.

Yes, optinMonster's exit-intent technology detects when a visitor is about to leave and triggers a targeted popup. Their published case studies report conversion rate increases of 200-300% for ecommerce sites. In our data, 20.38% of OptinMonster sites run WooCommerce, and many use it specifically for cart abandonment recovery alongside Google Remarketing (23.34% overlap).

Both are WordPress-first popup tools. Popup Maker is much larger by footprint, at 116,786 domains against OptinMonster's 21,418, and it is free where OptinMonster is paid. OptinMonster carries the more commercial feature set (exit-intent targeting, A/B testing) and a somewhat larger average customer: half its companies employ more than ten people.

Very few that we can measure, and we would rather say so than inflate it.

Privy (6) and Mailmunch (5) follow. These are small numbers against 21,418 active domains.
