Sailthru for WordPress

62 Quality Score

Active Installs

15/30

At roughly 2,000 active installs, the plugin has a small footprint that reflects Sailthru's niche, enterprise-leaning customer base rather than broad WordPress adoption.

Update Freshness

25/25

The plugin was last updated in June 2026 and is tested against WordPress 7.0, which is excellent and indicates an actively maintained codebase.

User Rating

0/15

A 0/100 rating from zero reviews means there is no community signal to lean on, so you are trusting the developer rather than user feedback.

Support Health

8/15

With zero support threads opened and none resolved, there is no public track record to gauge how responsive the maintainer is when problems arise.

WP Compatibility

15/15

The plugin supports WordPress 5.5 and up and is tested against 7.0, giving it a strong compatibility score across modern installations.

What It Does

Sailthru for WordPress connects your site to the Sailthru email marketing platform, allowing you to embed sign-up forms, pass user data into Sailthru's personalization engine, and trigger transactional or marketing emails from WordPress events. It is a bridge plugin designed for sites already using Sailthru as their ESP rather than a standalone email marketing tool.

Who It's For

This plugin makes sense for mid-size to enterprise publishers, ecommerce stores, or media companies that are paying Sailthru customers and need WordPress to feed content and user behaviour into that platform. It is best suited for teams with developers or marketing operations staff who can configure API keys and template the integration to match their Sailthru workflows.

Who Should Skip It

If you are not already on Sailthru, there is no reason to install this plugin, as it does not function as a general email tool. Small sites, bloggers, and WooCommerce shops looking for a simpler, self-contained newsletter or SMTP solution will be better served by one of the mainstream alternatives below.

The Bottom Line

Sailthru for WordPress is a well-maintained but narrowly scoped integration that earns a 62.28/100 on PluginCheck, held back mostly by its tiny install base and zero user ratings. It is a sensible choice only if you are already paying for Sailthru and need WordPress to feed that platform; everyone else should look at the more popular alternatives. Treat it as a specialized connector, not a general email solution.
