There are many types of email marketing campaigns. However, there are four principal types of marketing emails, which include:

Promotional emails: Promotional emails advertise a company’s products or services, often by promoting sales, discounts, seasonal events, company events, and so on.

Product update emails: These emails inform customers about new or updated products.

Digital newsletters: Digital newsletters are regularly sent to a company’s email list to inform customers of company or industry updates by providing interesting articles or relevant news.

Transactional emails: These emails are typically triggered by a customer action. For example, if a customer buys a product, they may receive a confirmation email or a follow-up email that asks for their feedback.
