MailOptin on new websites

1. MailOptin appeared on 14 new sites in the last 30 days.^[1]
2. Almost all new MailOptin sites also use Web Font Loader.

The line is the 7-day average share of new sites that use MailOptin, day by day for the last 90 days and weekly before that (left of the dashed line). It starts at our first detection. The shaded areas were measured against a different set of sites, so the line can step there without MailOptin itself changing.^[2][3]

1. These figures cover websites that went live since April 2026, not the web as a whole.
2. Grey: before 8 July 2026, we only tracked launches from launch platforms. From that date we crawl the wider web as well, so the share is measured against a much larger set of sites. For one continuous measure, view launch platforms only.
3. Amber: 8 July to 10 September 2026, before we improved our infrastructure to index new sites much sooner, often on the day they go live. Sites found that early often haven't finished setting up, so anything usually added after launch reads lower from 10 September. We record each site as it was when we found it.
4. Country comes from what each site says about itself, such as a company registration, legal terms or a phone number, not just its domain ending. Too few sites state their country plainly for the usual count, so this one also counts single signals: a country domain ending, a phone number (for North America, its area code), a location the site declares in its own page metadata, or a country-specific vendor stack and the page language where they agree and nothing contradicts them. Read these as likely rather than certain.
5. Some products people expect to see here are filed under a related category: Wordpress Theme.
