To disable Salesforce triggers you aren't using you will need Admin permissions in Salesforce.
Let's get started
1. In your Salesforce Setup, go to Quick Find and enter Custom Settings
2. Select the Custom Settings result
3. You should see an entry for Postal Trigger Settings, click Manage
4. Click New
5. You can click the checkbox next to Disable all Triggers to have no Apex jobs run. Then Save.
Alternatively, you can disable individual objects you aren't triggering off of. To do that enter the object types in the Disable Objects field.
Valid Object Types
- EVENT
- OPPORTUNITY
- TASK
You can disable multiple objects by separating them with a semi-colon. Example to disable both Tasks and Events:
EVENT;TASK
