    Check Your Email Spam Score Before Sending

    Every mailbox provider uses spam filters! Email Spam Tests are also part of deliverability best practices. Before sending it to your list test your subject line and message content with a spam checker tool.

    A spam score checker runs the content of your email and other factors like domain, IP, from-address, and SPF/DKIM/DMARC/Reverse DNS records. Knowing your spam score based on the test helps you estimate deliverability and avoid the spam folder.

    How to stay in the Inbox?

    An email spam checker tool cannot see the abuse or bounce rates. The best way to ensure consistent inbox placement is to email interested and engaged subscribers. Keep your bounce rates low and invalid email addresses out of your list with email address validation. Validate as soon as users subscribe and repeat email address testing every few months to identify deactivated accounts, complainers, and accounts that have become spam traps.
