An Email List is a collection of email addresses and related contact information used for sending messages, newsletters, marketing campaigns, or sales outreach. In B2B and B2C marketing, email lists are essential tools for driving engagement, nurturing leads, generating conversions, and building long-term customer relationships.
A well-targeted and compliant email list is the foundation of every successful email marketing and sales automation strategy.
