Marketing is the widest category here because “marketing” covers everything between a visitor arriving and a sale happening. The plugins here split into recognizable jobs: email platforms that live on your site (MailPoet, FluentCRM) versus connect-to-a-service ones (ConvertKit, HubSpot); capture and popups (OptinMonster, Thrive Leads, Hustle); social distribution (Revive Old Posts, Social Auto Poster Pro, Social Warfare, Monarch Social); and the specialists — affiliate management (ThirstyAffiliates), content planning (CoSchedule), Pinterest (Tasty Pins). Start from the job, not the brand.
