Building an Email List: The foundation of email marketing is to have a list of subscribers who have willingly provided their email addresses and given permission to receive emails from your business. Building an email list can be done through website sign-up forms, lead magnets, contests, and other methods.
Email Service Provider (ESP): An email service provider is a software or platform that facilitates the creation, sending, and management of email campaigns. Popular ESPs include Mailchimp, Constant Contact, and ConvertKit. These platforms often provide features like list management, email templates, automation, and analytics.
