  • Check Your Spam Score Before Sending

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

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

  • Test and Retest to Optimize your Content

    Check your email for spammy text and HTML content before you start your campaign. Our email spam checker can help you stay on best terms with mailbox providers and help you stay out of the spam folder.

    Identify issues with content, format, domain setup and mail server configurations. Following good sending practices is one of the best ways to improve IP and domain reputation. We can help you solve the problems that prevent your messages from reaching the inbox folder.

    How to stay in the Inbox?

    An email spam checker cannot see the abuse or bounce rates. The best way to ensure consistent inboxing is to email to 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.
