Email marketing is one of the most effective tools for growing sales, but it only works if your emails end up in prospects’ inboxes. Unfortunately, spam filters can sometimes block or send emails straight to junk folders, and it’s often hard to figure out why your campaigns are failing. Using a variety of spam tests can help you preemptively identify problems with your content or subject line before it’s too late and increase the chances that your subscribers receive your emails.

How do you check if an email is marked as spam?

A spam filter test is a check that assesses – based on a series of common traits – how “spam-like” your email content is. Test spam email content is a good idea to run a spam filter test for every email before you send it out, as doing so can significantly improve your deliverability rates and ensure that your campaigns get delivered to the right inboxes.

There are many elements that can cause an email to be marked as spam. Some of these include the use of all caps and excessive punctuation, words that suggest a sense of urgency (e.g.,’make money’, ‘get it now’, and ‘100% satisfaction’), words that sound illegitimate or make exaggerated claims, and links that redirect to suspicious websites. Having these elements in your emails can cause you to be flagged as spam by major content filters and email service providers.

Some of these issues are a result of the email service provider’s policies, while others can be fixed with consistent email marketing best practices over time. For example, if your sender score is too low, it may take some time for you to improve your reputation.
