We check all email addresses on a list against established IETF standards with an advanced engine for email validation according to syntax.
Email addresses issued by free email service providers are unlikely to be linked to corporate accounts and business leads.
Temporary email addresses are supplied by email service providers like Mailinator, GuerrillaMail, or 2,000+ others. They are created for short-term purposes in mind and can be fraudulent.
Branded email addresses are typically accompanied by a valid domain that has its DNS MX records properly configured.
An email address without a mailbox cannot receive messages and so likely does not add value to your email list or might be suspicious.
Catch-all addresses aren’t always actively used by individuals and so may have questionable value on an email list.
