Color coding

To immediately understand email deliverability, the table features colors that signal if the value is good, bad, or just average. 

• Green - good results - exceed what we perceive as a satisfactory value for a particular data point.

• Yellow - borderline results - neither good nor bad, and may require your attention or action.

• Red - the result is under the threshold we consider satisfactory and it requires your action to improve the performance of a specific mailbox provider.
