Spam Feedback: GPT includes information on spam complaints generated by Gmail users, enabling senders to monitor complaint rates, investigate potential issues with email content or frequency, and take corrective actions to reduce complaints and improve sender reputation.
Authentication Status: GPT verifies the authentication status of sender domains using SPF, DKIM, and DMARC protocols, highlighting any authentication failures or configuration issues that may impact email deliverability and security.
Recommendations and Best Practices: Based on analyzing email performance data, GPT recommends improving deliverability, enhancing sender reputation, and optimizing email campaigns for Gmail users.
Deliverability Analysis: An email marketer uses GPT to analyze deliverability metrics and identify trends in inbox placement, spam rates, and domain reputation across different email campaigns, adjusting sending practices and content strategies to improve overall deliverability.
