Flexible payment plan

Don't paint yourself into a corner with Postmark's monthly emails plans. With our flexible pricing, no more worrying about not using up your emails within a month. Unlike Postmark's mandatory monthly charge, you only pay us for the credits you use.

Attachment storage

Upload frequently used attachments to your account with ZeptoMail's File Cache. With your files stored in ZeptoMail, you no longer have to upload attachments each time an email is sent. You can store your files permanently to your ZeptoMail account to use whenever required.

Custom tracking domain

Use the domain of your choice to track recipient activity. Without a shared tracking domain, you not only build a good deliverability and sender reputation, but can also ensure that your emails and links are white-labeled.

  • Do you offer a free trial?

    Your first credit is on us. ZeptoMail offers 10000 free emails on approval of the account after sign up. These emails can be sent anytime for a duration of 6 months from the time of sign up. You can integrate your application with ZeptoMail and use the trial emails to explore the platform.

  • Do you offer bulk emails?

    ZeptoMail is a dedicated transactional email sending service. We do not allow bulk or marketing email sending from our platform. Separating marketing emails from transactional emails is crucial for a good sender reputation and in turn good deliverability. Each new account in ZeptoMail is verified by our team to ensure that user needs are compatible with our policy.

  • What is a custom tracking domain and why is it important?

    A custom tracking domain is any domain of your choice that you use to track clicks and opens on your emails. A default tracking domain is shared by multiple senders. By using a custom domain owned by you, you can improve the sender reputation of your emails resulting in better deliverability. Also, when you use a custom tracking domain, all the displayed elements on your email will show your domain instead of ZeptoMail, essentially "white-labeling" your emails.
