Email Deliverability Rate: What It Is And What It Is Not

Using advanced tools like inbox placement can determine the efficiency of the marketing program. 

Still,before you invest in an email deliverability tool, it is important to understand the nuances of this software.

Here are a few reasons why deliverability rates are affected: 

• Your reputation 
• Past history with recipient’s server
• Verification/authentication 
• Content quality
