Global Email V4 has several new features compared to Global Email V3. One of the main new features that is directly relevant to our users is a new field: Deliverability Confidence Score. This new field gives users a faster and easier way to interpret and use the results of our email verification. It is simply a single number in the range of 0 to 100. It is derived from our existing result codes, as well as many other dynamic data points.
Overall, the deliverability confidence score represents our confidence that an email sent to the address in question will not bounce.
Our deliverability confidence score can significantly simplify your process of deciding whether to send an email to an address. You can split the 0-100 range into multiple parts, or simply set a single threshold to be used to keep or discard emails.
In general, the deliverability confidence score is mainly intended for use when you have a list of emails to check for the purposes of sending emails right away – marketing campaigns, newsletters, etc. In this scenario, you would process your email leads, filter by deliverability confidence score, and send accordingly.
On the other hand, if you are cleansing emails in a database setting – meaning you may or may not send any emails in the near future – we recommend still using result codes. For example, result codes allow you to check syntax only, or to perform more granular analysis on your end.
It is important to note that syntactically correct emails do not always have the highest deliverability confidence scores. Our underlying email verification is only improving with time, which is reflected in both result codes and the deliverability confidence score. For example, factors such as the reputation of the email provider and our data on how likely the owner of the email is to report emails as spam are still taken into account in our process.
