Ensure your emails display perfectly on mobile and desktop devices without any rendering issues.
Email looks great on desktop but not on mobile.
Images fail to load, and no alt text is provided.
Email clients don't display your chosen fonts correctly.
Dynamic content or interactive elements are blocked or removed.
Button borders disappear, causing the CTA to blend into the background.
Problems with background images.
Before running tests with our tools, you can preview your email. This feature shows how your email will appear on mobile and desktop devices on average.
Tip: you can share a preview link with colleagues or clients for approval.
The Free subscription plan allows you to send test emails to your email address only — the one you used when registering your account with Stripo. Paid plans allow you to send test emails to multiple addresses, with the number of daily tests depending on your subscription level.
Test across 98 mobile, desktop, and web clients. Customize the email clients and devices for screenshots.
You can also download and share preview images with your team and track changes over time by reviewing previous test versions.
