What to expect with Inbox Preview tests:
- Each email client you select counts as one preview, e.g., Outlook 2019, Gmail in Firefox, or SpamAssassin
- A limited number of free previews are offered for the basic plan. When you send your tests, you’ll see how many credits you have remaining on your account for that month.

- Results can take a few minutes to return. If they take longer, check status.litmus.com for any known issues.
- To run an Inbox Preview test, we send the email to a unique Litmus email address. These addresses show up in Subscriber Search with the @emailtests.com domain.
Reviewing SpamAssassin results
You have the option to send a SpamAssassin test with Inbox Preview. The test will run, and a score will return. Scores between 0-3 are best. Any score above 6.3 will likely trigger a spam block at the receiving ISP. It is possible to receive negative scores. Any score below 0 is perfectly acceptable.
Note: Only the HTML version is sent. This returns results that the message is missing a text version, "Your email doesn't include a plain text alternative to your HTML content. It’s best practice to always include a plain text part in your email."
How SpamAssassin works
SpamAssassin applies some rules and filters to your email message to determine if it is spam or not. It is mainly looking at the body or header fields of the message to make a decision. The content of the email is not reviewed. Header content includes details about your DKIM record, IP address, and the WordFly SPF. These elements are all part of your WordFly infrastructure that we manage for you.
SpamAssassin is a good general test to start and then run your own tests to various ISP accounts to see how your email gets through. ISPs all filter differently. Paid email services such as Comcast always filter more vigorously. Gmail is great for content filter testing. Read more about how to stay out of the spam folder.
