Marketing vs Transactional

Marketing emails are bulk emails that are sent with the intention of selling or promoting a product or service. Transactional emails are unique emails that convey important information. They can be of different types, such as account information, invoices, and more, depending on your business.

 
8

Why are they important?

Transactional emails are the most important emails for any business. With an 8X higher open rate than marketing emails, they help foster trust, build your reputation, and establish communication with users. When done right, they're key to customer retention.

Highlights

 DeliverabilityEmail SegmentsEmail InsightsReputationTemplates

Great deliverability for your emails

We do one thing and we do it well—transactional email delivery. With an exclusive focus on transactional emails, our email sending is optimized for good deliverability and fast delivery. Your users will no longer be left waiting for their verification or password reset emails.

Segment your emails

If you run multiple businesses, applications, or send different types of transactional emails, having them cluttered together can be chaotic. With ZeptoMail, you can segment emails into streams by using Mail Agents. Each group comes with its own analytics and credentials.

Segment your emails

Deeper insight into your emails

You can enable email tracking for the emails you send out to view recipient activity. You can then view detailed logs and reports of each email that's processed through your account. It helps to stay on top of your email performance and troubleshooting.

Deeper insight into your emails

Protect your sender reputation

Having too many bounces or spam complaints can affect the delivery of your transactional emails. The suppression list in ZeptoMail allows you to block sending and tracking for specific email addresses that cause bounces, so you can protect your reputation.

Protect your sender reputation

Readily available templates

Writing the same email repeatedly eats up time that could be spent building your business. ZeptoMail comes with email templates for common transactional emails. You can pick from the ones available, or create your own from scratch.
