For your campaigns and templates, as part of the review process, you can generate a spam report. The spam report tests your template against a set of filters and displays a pass or fail result per filter. Filter types include personal and corporate, and some of the filters are email authentication tests. More details on each filter are listed below.
NOTE
Failures found by the spam filters do not necessarily mean that your email will land in the Spam Folder. The filters run by this spam report are only able to check DNS Setup and specific spammy keywords, and it is important to keep in mind that DNS setup is only half the equation. Sending practices also weigh into the decision heavily.
For optimal send performance and inbox percentage, you should consider both Deliverability Setup (DNS, DKIM and optionally SPF and DMARC) and Deliverability Best Practices (sending to engaged users, using suppression lists, etc.). If you have concerns or need more information, reach out to your customer success manager for additional recommendations.
My template failed one or more filters in the report: what next?
Unfortunately, Iterable does not have control over what content gets sorted into spam/junk folders. Email reputation controls access to the inbox. Whether your email gets to the inbox is entirely controlled by the ISP (Gmail, Yahoo, Hotmail, etc.) and is determined by their proprietary algorithms. However, there are some steps you can take to maximize your inbox percentage:
Confirm that your DNS records are set up (check Settings > DNS Setup). Remember that if you change your sending domain, you will need to re-add your DNS records. DNS records can take up to 24 hours to update.
Confirm that you have enabled DKIM (SPF and DMARC are optional), which are email authentication techniques that prevent email "spoofing" and tell ISPs how to route messages that they perceive as not from you. This should have been done when you updated your DNS records.

Is your IP warm? Are your lists clean and recipients engaged? Specifically, review:
If users are reporting that your content is going into spam, tell them to indicate that it's not spam. This is one of the most effective ways of getting ISPs to look favorably upon content from you, since their own users are doing the vetting.
If you think you may have issues with a specific ISP or mailbox provider, check their postmaster page, which will generally have guidelines aimed at helping senders follow best practices. Some postmaster page URLs are listed below.
For more information on deliverability read the Deliverability and Unsubscribes articles. Also, discus your practices with your Iterable customer success manager to help determine what can be done to ensure improved deliverability, which results in better inbox placement.
Generating the report
The spam report can be accessed when reviewing a campaign or a template. During the campaign review process, on the Review & Launch page, there is a Spam Report tab in the right-hand Previews section. Click on that tab to view the spam report. For old campaigns or templates, you will need to click Regenerate Spam Report in order to initiate the filter tests. For new campaigns or templates, the tests should run automatically. The tests will usually take at least 20 minutes to run, but sometimes much longer.
To access the spam report when editing a template, scroll to the bottom of the screen and click the Check Spam Report link on the left-hand side of the screen.
In addition, the Spam Report option is also available for each of the listed templates on the Manage Templates page.
