Gmail sets anti-spam requirements such as ``setting up an unsubscribe button'' and ``email authentication'' for users who send more than 5,000 emails a day



Spam emails (spam) that are sent indiscriminately and in large quantities are not only annoying, but can also be used for malware distribution and phishing scams , so email services have introduced various anti-spam measures. Gmail has newly set requirements for bulk senders who send more than 5,000 emails a day, such as ``installing an unsubscribe button in emails'' and ``implementing email authentication'' as a spam countermeasure.

Google to bolster phishing and malware delivery defenses in 2024

Gmail has long implemented AI-powered defenses to combat spam, blocking 15 billion emails a day before they're sent to users and blocking over 99.9% of spam, phishing, and malware. It seems that the block was successful. However, spam still bothers many users, and Neil Kumaran, group product manager for security and trust at Gmail, said, ``Nearly 20 years after Gmail was introduced, it's still a threat we face.'' is more complex and pressing than ever before.'

Gmail has therefore announced new anti-spam requirements for bulk senders (users who send more than 5,000 emails per day). Bulk senders must comply with the following requirements by February 2024:

◆1: Authenticate the sender of the email
Users sending bulk emails with Gmail must authenticate according to 'established best practices.' Gmail explains that by performing authentication using DomainKeys Identified Mail (DKIM) , an email authentication technology, it can protect email domains from spoofing and prevent sent emails from being classified as spam. I am.

'Many bulk senders do not have proper security protections and system configurations, making it easy for attackers to infiltrate their systems,' Kumaran said. We focused on a fundamental aspect: verifying that the sender is who they say they are. This may seem basic, but it overcomes the outdated and inconsistent systems on the Internet. When you think about it, sometimes you can't confirm who sent the email.'



◆2: Enable easy way to unsubscribe
Newly, bulk senders are required to implement a ``button that allows Gmail recipients to unsubscribe from commercial emails with one click,'' allowing users to easily unsubscribe from email. Bulk senders must process unsubscribe requests and stop email delivery within two days of a user's request.

Instructions on how bulk senders can implement an email unsubscribe button can be found on the help page below. 'These requirements are built on open standards, so if senders implement them, everyone who uses email will benefit,' Kumaran said.

◆3: Confirm that the rate of users identifying it as spam is below the threshold
To prevent Gmail users from suffering from spam, bulk senders are required to keep the percentage of their emails classified as spam below a certain threshold. Overseas media outlets CNBC and BleepingComputer have pointed out that if the spam rate on Postmaster Tools , a tool that allows you to check the number of spam email reports in Gmail, reaches 0.3% or higher, emails may not be delivered properly.

Gmail is not the only company with a set of requirements; Yahoo! in the US has also announced similar requirements for bulk senders. Marcel Becker, Senior Product Director at Yahoo! We're looking to improve the experience.'
