With this in mind, there are also several third-party tools that can help you monitor your sender reputation and deliverability performance.
Third-party deliverability tools
- Google Postmaster Tools
Google Postmaster Tools is Google's reporting tool for email sent to personal Gmail accounts (@gmail.com and @googlemail.com). It helps you follow Gmail’s best practices and provides reporting on sender reputation, authentication, encryption, delivery errors, and user-reported spam rates. Gmail does not report spam complaints directly to Klaviyo, so use Postmaster Tools to monitor those complaints. You must verify your sending domain before data appears, and low sending volume can leave dashboards empty. See Google's setup instructions. - Smart Network Data Services
Smart Network Data Services is only applicable for Klaviyo users with a dedicated IP. It is Microsoft's IP reputation monitoring service for email sent to Outlook.com and Hotmail accounts. Request access in SNDS to the IPs you are responsible for to view their data. - Validity Engage
Everest's inbox placement and deliverability monitoring are now part of Validity Engage. It offers inbox placement testing, sender reputation and authentication monitoring, email validation, design testing, and analytics. - Litmus
Litmus, now part of Validity Engage, allows you to preview emails in various email clients before sending. It also includes analytics to see how your customers are engaging with your emails, and pre-send testing that allows you to see where your emails are landing in different email clients' inboxes, including international clients. Learn about the Litmus Extension for Klaviyo (available in Google Chrome). - Email on Acid
Email on Acid focuses on email testing. They enable email previewing, campaign precheck, and spam testing. - Kickbox
Kickbox is a list verification tool that integrates with Klaviyo. It helps you review the quality of your subscriber lists. Email verification does not guarantee inbox placement.
