Black Arrow Cyber Advisory 19 February 2024 – Google and Yahoo Change Email Policy Impacting Delivery of Emails from Businesses, What You Need to Know

Executive summary

Google and Yahoo are tackling spam with their new rules for bulk emails. Gmail and Yahoo have introduced new regulations for bulk email senders, which applies to anyone sending 5,000 or more messages to personal accounts in a 24 hour period.
