Input Best Practices
While text encoding is a rare issue with email addresses, note that Global Email will not support any wrongly-encoded special characters or non-Latin characters. In general, text encoding is an important part of any data enterprise.
This service can deal with multiple languages and scripts. It expects UTF-8 encoding. Be on the lookout for question marks (?), squares (▖) or other unwanted characters like �. They may be an indication of encoding issues and may result in data loss. Bad encoding or character loss is not something our service can correct for you.
Here is a sample response of the REST request from above.
Even when activated, WhoIs sometimes returns incomplete information. We simply relay what we get from them.
The “Mxserver” field is only used with Premium validation.
If receiving a batch response, “TotalRecords” will reflect the number of records, and each record will be in the “Records” array, each having its own “RecordID”, “Results”, etc.

Domain Type Indicator
Predicts if email belongs to a personal or business/organization email by analyzing the domain.
The known number of breaches that this email account has been involved in.
Global Email includes a DeliverabilityConfidenceScore (DCS) with each email.
The DCS is a single number in range 0-100 that represents how confident we are that an email will successfully send. It can be used as a quicker and simpler way to filter emails, either as a first step before diving into result codes, or for a single pass of data cleansing.
DCS is not simply a numerical representation of our result codes, though. We leverage various reference data to further refine DCS, which also makes it dynamic - even more dynamic than our existing result codes.
While certain use cases will vary, our general recommendation for using DCS is:
0 to 30
Do not send.
31 to 60
Email delivery not guaranteed.
61 to 100
Send mail. There is a high chance of email delivery success.
If you require more granular analysis, or just need to maintain consistency with other Melissa products, please continue reading to learn about Global Email’s result codes.
All Melissa products use result codes. Result codes are four-character, alpha-numeric codes to two letters followed by two numbers, e.g. ES01. Result codes are returned as a comma-delimited string with no whitespace, e.g. ES01,ES22.
The following table shows the most common result codes seen while using Global Email, and our recommendations for how to interpret them.
