What is an email list?

An email list is a collection of email addresses from people who have given permission to receive communications from your business. It serves as the foundation of effective email marketing, enabling businesses to send newsletters, promotions, and updates to interested subscribers.

Benefits of building an email list:

What is ecommerce email marketing?

Key components include:

Promotional emails - Product launches, discounts, and special offers
Transactional emails - Order confirmations, shipping updates, and receipts
