Email remains a vital channel for businesses to connect with their audiences, nurture leads and customers, and foster growth. However, without proper spam testing, emails may end up in the spam folder, where they could miss out on the potential for engaging with subscribers and driving conversions.

Spam test for outbound email marketing programs designed to prevent unwanted or malicious emails from reaching email recipients’ inboxes. Email filters assess the content, sender reputation and email formatting of each message to determine whether or not it should be delivered to the inbox or routed to the spam folder.

As spammers continue to evolve their tactics, it’s important for marketers to continually check where their messages are landing with a spam test to keep up with the ever-changing landscape of email deliverability. In addition to using a spam test, you can also make sure your email is protected by an ISP feedback loop, engage with industry forums, and take advantage of domain authentication protocols like DomainKeys Identified Mail (DKIM).

A Spam Score is the overall likelihood that your email will be deemed as spam by ESPs. It’s calculated by dividing the number of recipients who successfully received your email to their inbox by the total number of mailboxes you tested against.

In most cases, a high Spam Score means your email is at risk of being marked as spam and will not be delivered to the inbox. To improve your Spam Score, consider rewording subject lines, avoiding spam trigger words, and maintaining a text-to-image ratio in the body of your emails.
