Does email validation affect my IP reputation?
DeBounce doesn’t send any emails to the recipient’s address during the validation process. All processing is done on its servers, so your IP addresses and domains are not affected in any way by the DeBounce service. This means that your IP or domains never get blacklisted, since the plugin never uses them.
Does this plugin store email addresses?
DeBounce really cares about data protection and user privacy and never store any emails called from API.
