Email testing offers robust, pre-send testing of your emails, including in-app spam testing, inbox rendering previews, and link validation without leaving your workflow. It allows you to preview how an email is likely to perform across a wide range of inbox providers, devices, and spam filters, before sending.
The number of Email Testing credits available to you depends on your Marketing Campaigns or Email API plan. For more information on email plans, see our pricing page. Email Testing credits can be used for both Inbox Rendering Tests and Spam Tests, and all Email Testing credits (whether part of your plan or purchased as part of an add-on package) expire at the end of each month.
If you find yourself in need of more credits than your email plan offers, we offer additional Email Testing credit packages as add-ons to your monthly plan.
Packages for additional Email Testing credits are billed on a monthly, recurring basis and will continue to renew each month unless removed from your account.
Available Email Testing credit add-on packages are:
Email testing is available for both Marketing Campaigns and emails within API plans using Dynamic Templates.
To test an email:
Before you can create a test, you need to specify a Sender and include a Subject for your email. If the given Subject includes handlebars syntax ({{{subject}}}
), you must add a subject value under "Preview >
Test Data" for the Email Test to run successfully.
Every inbox rendering test that you run automatically includes a link validation test, checking that all URLs within your message are valid. Link validation tests do not deduct from your Email Testing credits.
Link validation tests check for the following pieces:
tel
and mailto
will fail this check even if they are valid, because they do not go to a website. If your link fails and goes to an http
or https
address, double check the link to make sure it goes to a valid, publicly accessible site.
