Benefits for Email Marketers

Authentication validation

Confirm your emails are properly authenticated (SPF, DKIM, DMARC) before you send. Correct authentication helps your campaigns reach the inbox instead of the spam folder.

Email weight & loading speed

Spot emails that are too heavy or slow to load, especially on mobile. Lighter, faster-loading emails give your audience a smoother experience and fewer reasons to drop off.

Structure and rendering checks

Check that key elements like font size, alternative text and text-to-image balance keep your email clear and displaying well across inboxes and devices.
