Overview
Sumo is a free lead generation and email capture tool for WordPress that provides pop-ups, a welcome mat full-screen overlay, a smart bar, and share buttons — all from a single lightweight JavaScript snippet. Its List Builder pop-up is the core feature, designed to capture email subscribers through exit-intent or timed triggers. Sumo’s free plan is genuinely capable for small B2B sites — it includes unlimited subscribers and integrates with Mailchimp, AWeber, and other email platforms. The paid plan at $39/month removes Sumo branding and adds advanced targeting rules. Sumo is best suited for content-heavy B2B sites that want basic email capture without paying for OptinMonster.
