Check your domain's email authentication, blacklist status, and sender reputation — instantly. Find out if your emails are landing in inboxes or spam folders.
What we analyze
We run your domain through the same checks that Gmail, Outlook, and Yahoo use to decide if your email lands in the inbox — or the spam folder.
The three pillars of email authentication. Missing any one can tank your deliverability.
We verify your mail exchange records, reverse DNS, and TLS encryption support.
We check your domain against 50+ major email blacklists used by inbox providers.
Domain age, sending history, and reputation signals that affect inbox placement.
Based on your authentication and reputation, we estimate your inbox vs. spam ratio.
On average, 21% of legitimate emails never reach the inbox. Poor authentication is the #1 reason — and it's entirely fixable.
