Summary
Achieving email whitelisting involves a multi-faceted approach, combining technical authentication with user-driven actions and responsible sending practices. Experts recommend prioritizing proper email authentication (SPF, DKIM, DMARC) as the foundational step to ensure inbox placement and minimize the need for whitelisting. Simultaneously, educating recipients on how to add your sending address to their address book or Safe Senders list in email clients like Outlook, Gmail, and macOS Mail is vital. Marketers emphasize the importance of building trust through valuable, relevant content, consistent sending schedules, and good list hygiene. Actively participating in feedback loops with ISPs can further enhance deliverability and reduce reliance on whitelisting. While whitelisting can improve engagement, relying solely on it is not a scalable solution; a strong sender reputation, built through responsible practices, is essential. It is also crucial to consider the potential security risks of whitelisting without proper authentication. Email administrators are aware of how to handle whitelisting requests from employees, emphasizing the need for businesses to prioritize these factors to foster successful, sustainable email deliverability.

What email marketers say
10 marketer opinions
To get emails whitelisted by a recipient's email admin, a multi-faceted approach is required. Educating recipients on how to add your address to their address book or safe sender list is a direct method. However, it's crucial to prioritize proper email authentication (SPF, DKIM, DMARC) to avoid spam filters in the first place, as whitelisting is more of a workaround. Sending valuable, relevant content, maintaining consistent sending schedules, and practicing good list hygiene are essential for building a positive sender reputation. Participating in feedback loops with ISPs can also help identify and resolve deliverability issues. While whitelisting may improve engagement, focusing on earning trust through content and consistent delivery is a better long-term strategy. It's also important to be aware of the security implications of whitelisting specific email addresses without proper authentication.
