Revenue-critical email
Inbox placement problems do not only hurt campaigns. They hit the operational emails that keep acquisition, access, billing, and retention moving.
Welcome flows, product nudges, and magic links have to land before a new user sees value.
Password resets and login links turn into support tickets when authentication fails silently.
Invoices, receipts, and renewal reminders need sender trust before timing and copy matter.
Outbound replies suffer when the domain itself starts from a trust deficit.
What gets fixed
The scan identifies the broken trust signals. The paid report turns those signals into a short repair queue your team can act on without decoding DNS forums.

Cost of bad deliverability
Use the estimator to size the possible business impact, then scan the domain to see the records behind the risk.
