Email checks move into the template builder
Email rendering, dark-mode and accessibility checks in a production workflow.
Platform release · 2026-09-01 · release announcementIssue 1 · September 2026 · Honourable mentionThe case
Mailgun announced Inspect for Salesforce Agentforce Marketing on 1 September. Once installed, the integration places more than 100 email-client and device previews inside the Lightning Email Template Builder. The release describes dark-mode previews, automated accessibility checks and unlimited seats, allowing people building templates to inspect their own work. It directs teams to install the product through Salesforce’s marketplace. The concrete change is the location of quality checks within creation; the announcement does not establish that a particular campaign improved or that automated checks guarantee compliance.
The observation
Quality is easier to act on when the check sits beside the work being changed.
Evidence and context
Feature claims come from the vendor release, not independent testing.No independent usability or performance results.
