Spam Folders Kill Campaigns

Spam filters are ruthless, without a proper spam score checker for emails, one wrong signal can send your message straight to the spam folder.

Bad HTML, excessive links, irrelevant keywords, or a tarnished domain reputation; any of these can trip spam filters.
And guess what? Even legitimate emails from trusted brands can land in spam if you don’t check before sending.
That’s why you need a reliable email spam checker tool that doubles as an email deliverability spam test, built to think like an email marketer, not just a machine.
