Does Litmus provide deliverability testing or inbox monitoring?
We do provide seed list testing for reputation scoring. This will check your email for reputation scoring across these clients, so you will see if your sending address is blocked by these ISPs/filters.
While Litmus offers feedback in regards to scoring on specific server-side and ISP filters, we do not offer inbox placement or monitoring services. Our reputation scoring will give you feedback about the IP that your emails are sent from, but does not give deliverability tracking/trends or blacklist testing for your campaigns over time. This will only show if your email will pass or fail these filters.
