Definition
Deliverability is a Setup page that controls the org's email sending settings and access levels. Administrators can configure the access level for sending email (No Access, System Email Only, or All Email), which determines whether users, workflows, and Apex code can send outbound emails from the Salesforce org.
Real-World Example
When setting up a new sandbox, the admin at CloudBridge Solutions navigates to Deliverability and sets the access level to "System email only" to prevent test automation from accidentally sending emails to real customers. Once user acceptance testing begins with test email addresses, she changes it to "All email" so testers can verify email functionality.
Why Deliverability Matters
Deliverability is a foundational element of Salesforce administration. Admins rely on it to control how users interact with the platform, ensuring that the right people have the right access while maintaining data integrity across the organization. Misconfiguring this area can lead to security gaps, data leakage, or frustrated users who cannot do their jobs.
As your Salesforce org grows and evolves, Deliverability becomes increasingly important for governance. It helps administrators enforce business policies without writing code, making it an essential tool for the 80% of Salesforce customization that happens declaratively through clicks, not code.
How Organizations Use Deliverability
- •Globex Industries — Configured Deliverability to enforce their data governance policies across 500+ users. By setting up proper controls, they reduced unauthorized data exports by over 90% and passed their annual security audit without any findings for the first time.
- •Initech Corp — Used Deliverability to streamline their onboarding process for new hires. Instead of manually configuring access for each person, they built standardized configurations that could be assigned in minutes, reducing IT onboarding time from two days to under an hour.
- •Umbrella Co — Applied Deliverability as part of a broader org cleanup initiative. By auditing and optimizing their setup, they improved page load times, reduced user confusion caused by unnecessary fields, and made their Salesforce instance more maintainable for the admin team.
