Gmail has introduced a Deliverability analysis section in the Compliance status dashboard of Postmaster Tools V2, providing senders with clear verdicts and recommended actions based on their data.
✅ Check it regularly, not just when performance drops, to avoid serious problems.
On May 27, we celebrate World Marketing Day, a great opportunity to honor people and ideas behind modern marketing🎉
Email remains one of the most effective marketing channels, but it only works when it reaches the inbox. Deliverability is key to the performance of your campaigns

•IP reputation tracks your sending infrastructure behavior
•Domain reputation tracks the long-term trustworthiness of your domain
