Sending Statistics 

To help you fine-tune your email-sending strategy, Nimbus Email Service (NES) automatically collects the following statistics regarding your sending activity:

  • Successful delivery attempts
  • Rejected messages
  • Bounces
  • Complaints
  • Email-Receiving Features
  • Email Processing Options

You can choose among several different options to process your incoming mail. Nimbus Email Service (NES) can deliver your messages to a dedicated server, or group functionality. You can also configure Nimbus Email Service (NES) to drop or bounce messages you do not want to receive.

Mail Flow Control

You have complete control over which mail you receive. You are not billed for any mail that is rejected during the SMTP conversation. Nimbus Email Service (NES) offers two mechanisms you can use to control whether Nimbus Email Service (NES) accepts or rejects incoming mail on your behalf. The first method is to use custom IP allow lists and block lists. If you know that you don't want to receive any mail from a particular IP address, simply add it to your account's IP address block list. You can also override block lists by adding IP address ranges to your allow list, which provides fine-grained control over your incoming email traffic. The second mechanism for controlling the acceptance of incoming messages is to set up recipient- based rules. Nimbus Email Service (NES) only accepts messages for which you have set up at least one rule that matches a recipient of the message.

Highly Customizable Receipt Rules

You can control what happens to incoming messages at the recipient level by setting up receipt rules, which collectively make up your account's receipt rule set. A receipt rule set contains an ordered collection of receipt rules, and each receipt rule contains an ordered collection of actions.


You can choose for Nimbus Email Service (NES) to simply notify you of incoming messages.


Nimbus Email Service (NES) publishes metrics in your Nimbus account when your receipt rules fail to successfully process a message, so that you will know to check your configuration. Metrics are emitted at the account level as well as at the receipt-rule level. You can set up monitors at the account level, and use the receipt-rule level failure metrics to pinpoint which specific receipt rules are having problems.
