The Subscribers check up functionality is an effective tool for assessing the quality and health status of your contact database.
This service allows for the verification of unreliable contacts, identifying dangerous email addresses and obsolete, incorrect, or disposable domains.
The verification activity helps to improve the sender's reputation with Internet Service Providers, increase contact interaction - the so-called engagement - and optimize the results in terms of delivery and reputation.
Regular use of this tool helps to decrease the number of emails that do not reach the recipient (bounce) and reduces the risk of complaints due to receiving unwanted communications, contributing to the improvement of deliverability performance.
