The system is full of bugs. All the 'Status' reporting and ranking systems are not accurate, making it difficult to monitor the performance of my inboxes.
The 'Health Score' warm-up feature is only for show. Several of my brand new inboxes that have been warming up with Reachinbox for 1 month still had 30% of emails landing in spam, but the health score says they are 100% healthy, which is very misleading.
Additionally, the DKIM, DMARC, and SPF record status was faulty. I configured them correctly, but they were showing 'Fail'. They fixed them after I questioned it and turned the status to 'Pass' within seconds, which makes the status reporting very questionable.
