Deliverability by ESP report
The Deliverability by ESP report breaks down your email delivery performance by different email service providers such as Zoho, Yahoo, Outlook, and others. This helps you identify which ESPs are successfully delivering your emails and which may be causing issues. This report shows:
- Delivered and bounced counts segmented by the recipient's ESP.
- Delivery rate across different providers over the selected time period.

Bounce by ESP report
The Bounce by ESP report shows bounced emails categorized by ESP. It helps you understand which providers are rejecting your emails and why. You can also use it to troubleshoot for a specific ESP.
Bounce categories
ZeptoMail provides a dedicated bounce reports dashboard that offers comprehensive information on email bounces. To help you diagnose and resolve delivery issues quickly, bounced emails are organized into clearly defined categories based on the reason for failure.

Here are the main list of bounces encountered by transactional emails.
Category | Description |
Connection issues | The sending server was unable to establish a connection with the recipient's mail server. |
Policy failures | The email was rejected due to the recipient server's sending policies, such as rate limits or authentication failures. |
Spam | The email was flagged or rejected as spam by the receiving ESP. |
User not found | The recipient email address does not exist on the receiving server. |
Invalid DNS | The sending domain has DNS configuration issues preventing delivery. |
Others | Any other bounce reason not covered by the above categories. |
