How much can ZeptoMail save you?

Does Postmark have all you need?

Postmark started as a transactional email-only service. They remained this way for a long time to maintain a good reputation and to ensure good deliverability for their users. They have now changed their long upheld stance to allow promotional and bulk email sending from their platform.

While they have different infrastructures for each group of emails, if you're only looking to send transactional emails, why pay a hefty monthly fee that also goes towards infrastructure you don't need and emails you won't use up? Deliverability is important but it does not have to be expensive monthly plans.

Exclusively transactional

With Postmark allowing promotional emails, ZeptoMail is uniquely positioned as a platform that has exclusive focus on transactional email delivery ensuring great deliverability.

Fast delivery

Speed of delivery is more important for transactional emails than for other emails. With delivery optimized for transactional emails, ZeptoMail delivers emails without any delay. Our delivery time to common ESPs is one of the best among our competitors.

Flexible pricing

Don't paint yourself into a corner with Postmark's monthly emails plans. Our pay-as-you-go payment plan ensures you pay for emails you use and not the ones that expire at the end of the month.

Comprehensive analytics

ZeptoMail gives you in-depth insights into every email you send like opens, clicks, bounce details, stored content, and more, making troubleshooting a hassle-free process.

24/7 support

Your transactional emails contain crucial and time-sensitive information. If your emails can't wait, why should you? With our 24/7 customer support, you can get the assistance you need at any time.

Attachment storage

Upload frequently used attachments to your account with ZeptoMail's File Cache. With your files stored, you no longer have to upload attachments each time an email is sent.

Custom tracking domain

Use the domain of your choice for email tracking. By isolating the tracking domain, you not only build a good deliverability and sender reputation, but can also ensure that your emails and links are white labeled.

"ZeptoMail's API is probably the best in the market. We wanted to optimize delivery but no provider delivered more than 80% to inbox. With ZeptoMail, we have 92% delivery into the inbox. Another beauty of ZeptoMail is that you get the delivery report immediately after the relay."
