Overview
This article provides instructions for customer support representatives on how to adjust email bounce control parameters for specific EFS instances. These settings help manage email deliverability and prevent potential throttling issues with AWS SES.
Key Parameters
Four main parameters control the email bounce behavior:
-
bounce_rate_alert_threshold_percentage: Threshold at which warning alert emails are sent to customers (default: 5.0).
-
bounce_rate_limit_threshold_percentage: Threshold at which email throttling begins. Emails are sent to customers informing of this (default: 7.0).
-
bounce_rate_throttle_percentage: Percentage of emails allowed through when email throttling becomes active (default 10.0, but may be set to 100.0).
-
bounce_rate_calculation_period_days: Time window for bounce rate calculation (default: 30).
Accessing System Configuration
-
Log in to the Tivian EFS instance as root.
-
Click the gear icon at the upper right.
-
Select Options from the menu that unfolds.
-
Select "Platform cockpit" from the left sidebar.
-
Click on the "[root only] System configuration" tab.
-
In the search box, type "bounce" to filter the relevant parameters.
Adjusting Parameters for a Specific Instance
To modify bounce control parameters for a specific instance:
-
Locate the variable you want to change (e.g., bounce_rate_throttle_percentage).
-
Click on the variable to edit its value.
-
Enter the desired value:
-
For alerting threshold: Recommended value is 5.0.
-
For limit threshold: Recommended value is 7.0.
-
For throttle percentage: Recommended value is 10.0 (setting to 100.0 disables throttling).
-
For calculation period: Recommended value is 30 (days).
-
-
Save the changes.
