In the realm of email marketing, certain types of emails consistently show higher engagement rates. These include welcome emails, transactional emails, and personalized content emails. Welcome emails typically have open rates of around 50-60%, as they are the first point of contact and set the tone for future interactions. Transactional emails, such as order confirmations and shipping notifications, also see high engagement because they contain information the recipient is eagerly awaiting. Personalized content emails that cater to the recipient's preferences and past behaviors also show significantly higher engagement.
