Transactional Email Dashboard

The Transactional Email dashboard delivers a real-time overview of your email traffic, allowing you to:

Monitor overall delivery performance for submitted emails.
Identify issues, including hard bounces, soft bounces, and dropped messages.
Detect unusual patterns or sudden drops in performance across various time intervals.
Access detailed insights quickly using linked tools such as Live Search or Reporting.

The dashboard supports both operational monitoring and proactive issue detection, helping you maintain high deliverability and a strong sender reputation.

Disclaimer: Displayed Email Transaction Metrics & Chart Values

The email transaction data shown in this dashboard is retrieved from our monitoring system and visualized over fixed time intervals (e.g., 15 minutes). To ensure responsiveness and scalability, we may use data extrapolation or interpolation depending on query timing and data availability. This approach keeps metrics fast and clear for spotting trends.

Please note:

Discrepancies may occur between displayed values and exact counts due to metric sampling or system approximations. Shorter time periods capture fewer data points, which can increase statistical variance.
These differences are expected and do not indicate data loss or errors in the underlying systems.
Displayed metrics are intended for trend monitoring and operational decisions, not for exact reconciliation or accounting purposes.
For exact totals, refer to the Transactional Email Reporting area in myEAS.
We continuously improve our monitoring logic to ensure high data accuracy.

The dashboard uses a set of shared components and interactions consistent across all Retarus products. For general information about chart controls and visualization features, refer to Working with charts.

Dashboard layout overview

The dashboard consists of several key areas:

Timeframe selection and auto-refresh controls at the top
Transactions Overview panel with high-level status cards
Hard Bounce Events panel for bounce classification
Transactional Email–specific charts (Delivery Rate %, Message Rate)

Timeframe and auto-refresh

You can adjust the displayed timeframe using either quick ranges or a custom date and time range. Auto-refresh is available when a quick range is selected, ensuring that your data updates continuously during active sending periods.

For detailed information on timeframe controls and auto-refresh behavior, see Working with charts.

Transactions Overview

The Transactions Overview panel summarizes the lifecycle of your submitted emails within the selected timeframe. Each status is shown as a metric card that displays the total count and a percentage value.

Cards definition

Card	Description	Percentage relation
Submitted Total	Emails successfully received and accepted for processing. Each message is tracked from this point until it reaches a final status.	—
Dropped	Messages removed during processing before being sent—often due to suppression list rules.	`% of Submitted`
Sent	Emails processed and sent out by the Transactional Email service.	`% of Submitted`
Delivered	Emails successfully delivered to the recipient’s server.	`% of Sent`
Hard Bounced	Emails permanently undeliverable due to issues such as invalid addresses or recipient server rejection.	`% of Sent`
Soft Bounced	Emails temporarily undeliverable and classified as final soft bounces after several attempts.	`% of Sent`

Cards thresholds

To help monitor deliverability, certain metric cards include visual alerts. Colors and labels indicate whether values fall within typical industry ranges.

Card	Healthy	Monitor	Investigate
Dropped	< 2%	2% – 5% A common cause of high message drop rates is recipient removal by the Suppression List. Update your Sending List to exclude these recipients.	> 5% A potential issue has been identified. Analyze the Reporting to determine the cause of the high drop rate and implement corrective actions.
Delivered	> 97%	95% – 97% You can further improve your delivery rate by reviewing the Email Deliverability Guide.	< 95% Review the hard and soft bounce SMTP response codes in the Reporting to identify delivery issues.
Hard Bounced	< 2%	2% – 5% Maintain a healthy Sending List by removing hard bounces promptly and reviewing unengaged subscribers periodically.	> 5% Review the hard bounce SMTP response codes. Clean your Sending List and examine your opt-in procedure to protect your sender reputation.
Soft Bounced	< 2%	2% – 5% Review the soft bounce SMTP response codes in the Reporting to understand temporary delivery failures.	> 5% Review your sending volume and rate. A significant increase in email volume can cause throttling.

Hard Bounce Events

The Hard Bounce Events panel shows the specific causes of hard-bounced emails. Hard bounces are permanent delivery failures that typically indicate issues with the recipient address or domain configuration.

The panel categorizes messages by common hard bounce reasons, helping you quickly identify delivery problems. Click any hard bounce card to view the prefiltered Reporting for that SMTP status code.

Status	Description and possible actions	SMTP status code
Mailbox unavailable	Invalid or disabled email addresses. Remove them from your Sending List.	550
Domain not found	Recipient domain unrecognized. Check domain syntax.	500
Recipient policy restriction	Transaction failed due to local policy or restriction. Review the SMTP response codes from the recipient servers.	554
Full mailbox	The recipient's mailbox is full and cannot accept more emails. Reduce the message size or retry later.	552
Domain blocklisted	Your sender domain may be blocklisted. Ensure messages do not contain spam or malware characteristics.	553

Delivery Rate %

The Delivery Rate % chart shows how successfully your emails were delivered over time. It plots the percentage of delivered messages against all sent messages in hourly intervals within the selected timeframe. This chart helps you spot trends quickly and take proactive steps before delivery issues impact performance at scale.

The Delivery Rate % chart shows the percentage of successfully delivered emails over time in hourly intervals. Use this chart to identify trends and address delivery issues before they impact performance at scale.

A consistently high delivery rate (over 95%) indicates your emails are reliably reaching recipient servers.
Spikes or drops may signal delivery problems, such as increased bounce or drop rates, or changes in recipient behavior or infrastructure.
Lower rates during specific timeframes may result from issues with your sending list, message content, or recipient servers.

Message Rate

The Message Rate chart shows the distribution of email activity, helping you understand message volume and delivery outcomes over time. It combines all accepted emails into stacked bars, with each status represented by a different color. This chart is especially useful for teams sending in hourly batches or managing time-sensitive campaigns.

By default, the Delivered traffic is hidden to improve chart readability. The height of each bar reflects the total number of messages processed during each period, allowing you to:

Identify periods of high or low traffic
Visualize how failures (bounces, drops) affect total volume
Compare delivery success rates across different times of day

Investigating Delivery Issues

If unusual patterns appear in the dashboard:

Select an appropriate timeframe to focus on the affected interval.
Review metric cards for elevated bounce or drop rates.
Use the charts to pinpoint when issues began or how they progressed.
Open Reporting by clicking a status or event category.
Review SMTP response codes to identify the underlying cause.
Correlate patterns with campaign activity or sending list changes.
