Email Testing Made Simple

Real screenshots, real fast!

Preview your email in 119 combinations of the most popular email clients and mobile devices.

Unlike web browsers, email clients are far more strict when it comes to HTML and CSS standards. Just because your email renders properly in a web browser does not mean it will render correctly in every inbox. Our email testing service allows you to preview your email in 7 operating systems, 6 web browsers, and 41 email clients - all within one click.

Everything is included!! Pay-as-you-go or sign up for unlimited testing.

Email Testing

Preview your Email

Preview your email before you send it!
We manage hundreds of servers and mobile devices to deliver you the fastest results possible. No need to sign up for multiple email accounts, borrow devices, or computers. Results are completed within 5 minutes.

Code Analysis

Our Code Analysis identifies individual lines of code that are not supported in each email client.
Discrepancies are classified as critical, moderate, or minor. Critical errors might adversely affect your layout whereas minor errors might include unsupported fonts, alt, or title tags.

  • Flexible email testing options.

    Send us the content of your email in one of 4 different ways:

    • Send your email to your EOA account
    • Cut/paste your URL
    • Cut/paste your HTML
    • Upload a zip file

    Use absolute image references or opt-in for relative reference conversion.

  • Vertical & horizontal mobile views.

    Drag, slide, and rotate your email just like you would when viewing it in the actual device - no paging, no repeating headers! That's 4 screen captures for each rotating device:

    • Vertical with images enabled (default)
    • Vertical with image blocking
    • Horizontal with images enabled
    • Horizontal with image blocking
  • Fast, accurate, affordable.

    Real screenshots = 100% accuracy. Our average processing speed is 32.5 seconds per email client!

    We designed our pricing plans to accommodate consistent or fluctuating workloads. Pay-as-you-go or subscribe for unlimited testing services - the more you buy, the more you save!

  • Use any email service provider.

    No matter who you have chosen to send out your final email blast, our pre-deployment testing tools will help you ensure that your email looks good no matter where it is received.

    In fact, we recommend that you send your test email directly from your ESP in order to ensure the most accurate results.

  • Preview your ENTIRE email!

    Do you have a really long email? Does it wrap even longer in mobile devices? No problem! We support 7,000 pixels in height - that's 350% more pixels than our competitors!

    Each test includes up to 104 individual screen grabs - that's 509 million pixels per email test!

    Results are available in your archive for up to 3 whole months.

  • Pre-flight checks are built in.

    We don't expect you to keep up with all the trends in email renderability. When we find nuances, like the iOS "download remaining XX bytes" message - we publish a blog article, tweet about it, post it to our tips and tricks, AND add it to our pre-flight check when you run a new test!

    All this to keep you in the loop and improve the overall performance of your final email blast.
