Your domain against the million

What a DNS scan cannot see

This check reads the record receivers read. The reports they send name each host that sent under your domain and whether its mail passed. We parse them and mail you one summary a week. On a paid plan, the first report naming a new failing sender turns into an email that day. Pro covers 5 domains, $19 a month.
