Stop guessing how your emails will look. Mailgun Inspect embeds 100+ email client and device previews directly into Salesforce's Lightning Email Template Builder, so your team catches rendering issues before every send, without switching tools.
Highlights
100+ Email Client and Device Previews See exactly how your email renders across desktop, mobile, tablet, and webmail—including light and dark mode—across every major inbox environment. Catch rendering issues before they reach your recipients.
Native Salesforce Experience—No Tool Switching The Mailgun Inspect tab fits directly inside the Lightning Email Template Builder. QA emails as you build them—no tab switching, no external logins, no workflow interruption.
Thumbnail Grid for Fast Visual Review Scan all client renderings at a glance and spot problems immediately. Drill into any thumbnail for a full-resolution view, with forward/back navigation between clients and devices.
Re-Run Previews Selectively After Edits Regenerate your full preview set after significant template changes, or re-run a single device after a quick fix - without waiting for a complete new preview run.
Works Wherever Your Team Builds Emails in Salesforce Available across Sales Cloud, Service Cloud, Marketing Cloud Next, and Account Engagement. One integration, available everywhere your team uses the Lightning Email Template Builder.
Org-Level Setup, Unlimited User Seats A Salesforce admin configures the API key once via Named Credentials. Every user in the org gets immediate access—no per-user setup, no additional license fees per seat.
Protect Revenue and Reputation Before Every Send 42% of recipients delete emails that don't render correctly, and 17% never reach the inbox due to formatting issues. Mailgun Inspect finds these problems before your customers do.
Powered by Mailgun Inspect—Trusted by 150,000+ Companies The email QA platform trusted by Braze, Lyft, and Blueshift—now natively embedded in Salesforce so your team gets professional-grade email preview without leaving your CRM.
