Stripo built-in email testing tool
Ensure your emails display perfectly on mobile and desktop devices without any rendering issues.

Start with an email preview
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.
Test by sending it to your inbox
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.
Check accessibility
Our in-built tool scans against WCAG criteria and flags all issues — no manual review needed. You'll see warnings for missing alt text, low color contrast, undefined language attributes, and font sizes below the readable minimum.
Try URL checker
Every link, merge tag, and image checked in one click — find what's broken and fix it without leaving the editor.
Test with Email on Acid
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.
