There are several reasons why role-based validation is critical in email marketing:
Spam Filters:Email service providers (ESPs) may flag role-based emails as spam or bulk mail, reducing your deliverability rates. Engagement: Role-based emails often have lower engagement rates as they are usually monitored by multiple people, and specific actions may not be taken. Compliance: Role-based validation ensures compliance with anti-spam laws like GDPR and CAN-SPAM, which require valid consent from recipients.
