What Are Email Marketing Tools?

Email marketing tools are software platforms that enable businesses to create, send, and manage email campaigns to subscribers.

These capabilities help businesses create targeted campaigns that reach the right audiences with relevant content at optimal times, improving engagement rates and conversion outcomes.

Email marketing tools differ from basic email services in their focus on marketing functionality, compliance features, deliverability optimization, and business integrations. While personal email services handle individual communication, email marketing tools are designed for managing subscriber lists, creating campaigns, automating workflows, and measuring marketing performance.
