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.

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.
