About MailerLite plugin

An email list is the one marketing asset a small company owns outright, and the plumbing that fills it is visible from the outside. The MailerLite plugin is that plumbing: a connector published by MailerLite that drops subscription forms, pop ups and landing page embeds built in the hosted product into WordPress pages and posts, then syncs whoever fills them in back to the sending platform.

Detection therefore implies two facts at once, a WordPress site and an account with a specific email service provider, and the second is the commercially interesting half. Sending platforms compete for accounts that are already in motion. A site with forms wired to a provider has a list, a sending habit and a monthly bill, which is a materially different prospect from a site with a contact form and nothing behind it.

The connector is free, published under GPL v2 through the WordPress directory since 2015, written in PHP and maintained by the platform vendor rather than by a third party. Free and first party both matter for reading the list. Nobody installs a connector speculatively, because a connector is useless without the paid account on the other end of it, so there is very little noise in this population compared with general purpose plugins that people try and abandon.

Versions add a maintenance dimension. We hold 46 distinct releases across the installed base, and the one we record most often is 2.1.29. Wide version spread on a plugin that updates itself by default usually means a long tail of sites nobody logs into any more, and stale integration plumbing is a common cause of the quiet failure where forms still render but subscribers stop arriving. For a competing provider that is an opening. For an agency or a freelancer it is a repair job with an obvious pitch.

As of October 2026 the connector appears on 2,143 sites. A per domain lookup answers whether one prospect uses it, which is useful once you already have the prospect. The downloadable list answers what only exists in aggregate: how the user base distributes across countries and top level domains, how much of it overlaps with commerce plugins, and which segments a competitor has quietly taken. Detection reads the plugin's own asset paths and version markers in the delivered page, so a site that loads its forms through a bundler, a caching layer or a tag manager can carry the connector without announcing it. The count is a lower bound and should be used as one.
