MailGenius helps email senders check their email's deliverability and spam score so their messages reach the inbox instead of the spam or promotions folder. It checks SPF, DKIM, DMARC, blacklists, domain age, broken links and HTML content, then gives a full report with a score and tips to improve inbox placement, which can mean more opens, clicks and sales.
