What are the benefits of transactional emails?

Transactional emails provide users with updates and maintain communication throughout their buying journey. And so, these emails eliminate users' doubts and address their concerns at different touchpoints. Hence, help build trust and credibility.

3. Improves brand recognition

Another benefit is that you can promote your brand through these one-off messages. Then, when they often see your logo, colors, typography, etc., it'll be easier for them to remember your brand in the future.

4. Timing

One of the best benefits of transactional emails is that they are sent in real-time. It means that with effective email marketing, you can prompt the user to take any action and even turn them into loyal customers.

5. Relevance

With transactional emails, you can gather behavioral data about users' activity. You can then create personalized emails to add more value and relevancy to your emails.
