    What is a mass email?

    A mass email is a message sent to a large group of recipients simultaneously. Common types of mass email campaigns include:

    • Promotional campaigns: Emails promoting products, services, sales, or special offers to a broad audience
    • Newsletter campaigns: Regular email updates featuring content, news, or information sent to a mailing list
    • Transactional emails: Emails sent to confirm orders, shipping, payments, or other customer transactions
    • Drip campaigns: A series of automated emails sent to subscribers over time, often triggered by specific user actions or behaviors
    • Event campaigns: Emails promoting upcoming events, webinars, conferences, or other occasions
    • Segmented campaigns: Emails tailored to specific subscriber segments based on demographics, interests, or engagement level
    • Re-engagement campaigns: Emails aiming to re-activate inactive or lapsed subscribers and customers
    • Survey and feedback campaigns: Emails requesting customer feedback, reviews, or participation in market research

    The key characteristic of mass emails is that the same core message is distributed to a sizable audience instead of highly personalized one-to-one email communication. However, mass emails can still utilize segmentation and dynamic content to provide more targeted messaging to different subscriber groups within the overall recipient list.
