21% of marketing emails never reach the inbox. If yours are landing in spam, your entire email program is invisible.

One in five marketing emails lands in spam or gets blocked entirely. That means if you send 100,000 emails this month, 21,000 of them are never seen by the person you sent them to. Your flows are running. Your campaigns are going out. You are writing great copy and designing beautiful emails. None of it matters if the emails do not reach the inbox.

Deliverability problems are sneaky. They start small. Open rates dip a few percentage points and you assume it is the subject line. Revenue from email drops gradually and you blame seasonality. Then one day you realize your emails are going straight to spam for a significant chunk of your list and you have been burning money sending emails nobody sees for months.

The causes are almost always the same. Your sending domain is not properly authenticated with SPF, DKIM, and DMARC. Your list has dead addresses that bounce and damage your sender reputation. You send to disengaged subscribers who never open, which tells inbox providers your emails are unwanted. And you have no monitoring in place to catch problems before they compound.
