Understand role-based email addresses and their impact on deliverability
You will learn
Learn about role-based email addresses, and how they can impact your deliverability.
What are role-based addresses?
Role-based email addresses are shared email addresses, often used by groups within an organization rather than an individual. For example, a business’s support team may use an email address like support@business.com for customer communications.
How do role-based email addresses impact my deliverability?
Role-based email addresses typically don’t opt in to receive emails and generally have high spam complaint rates. They are more likely to bounce and negatively impact your sender reputation and deliverability. Klaviyo automatically blocks certain role-based email addresses from receiving marketing emails to protect your deliverability.
If a campaign or a marketing email in a flow includes a blocked role-based address, Klaviyo skips that recipient with the reason Skipped: Invalid Email Address.
Flow emails approved for transactional status are exempt from this role-based address check. Learn how to use flows to send transactional emails.

MM3 sends
MM3 messages are emails that result in communications with a cellular device (e.g., pagers and cell phones) in a non-email fashion such as a received text message.
The United States FCC maintains a do not email domain list here. All domains listed on this FCC page are expected to result in some form of electronic communication with the end recipient being a cellular phone device or pager. Unsolicited marketing communications to these device types are expressly prohibited and Klaviyo will automatically block sends to these domains.
