Google to bolster phishing and malware delivery defenses in 2024

In an effort to enhance email security, Google is implementing new sender guidelines in February 2024. Large senders dispatching more than 5,000 emails a day to Gmail accounts will need to set up SPF/DKIM and DMARC email authentication for their domains, offer a one-click unsubscribe option, handle unsubscription requests within two days, and maintain a spam rate below 0.3%.
