Email delivery firm, SparkPost, has announced new enhancements to its validation service, SparkPost Recipient Validation. According to SparkPost, the enhancements include additional data which doubles the number of bad email address it is able to detect. The feature identifies the bad email addresses using historical bounce data and analyzes the sending behavior of other SparkPost customers to allow customers to filters the bad emails.

“SparkPost uses typo detection, DNS checks, and especially historical bounce data from thousands of other customers, based on its sending 37% of the world’s B2C and B2B email,” said Charlie Reverte, chief product officer at SparkPost. “That way customers can remove bad emails from their lists before sending so they don’t hurt your sender reputation with ISPs.”
