Microsoft 365 users have been warned that they need to verify outgoing emails to ensure they continue to be delivered, in the wake of Gmail’s new anti-spam rules.
A recent Gmail blog post notes how from 2024 the email provider will “require large senders to authenticate their emails, provide easy unsubscribe options, and stay below the reported spam threshold,” otherwise senders risk having their emails sent straight to the spam box or not delivered at all.
This move is intended to protect consumers from redundant messages, but it’s also a measure that will likely cause headaches for senders in the coming months.
Microsoft is tackling Gmail’s anti-spam rules
The Microsoft Defender for Office 365 team said (via Beeping computer): “By setting up email authentication for your domain, you can make sure your messages are less likely to be rejected or marked as spam by email providers like Gmail, Yahoo, AOL, and Outlook.com.”
Gmail will needed soon senders to use SPF/DKIM and DMARC email authentication, which is expected to reduce the impact of some phishing attacks. Senders should also make unsubscribe easy with one click.
It’s likely that senders who make these changes won’t isolate them just to Gmail users, and as such, all email recipients will likely benefit from the new rules coming into effect from Google.
Microsoft added: “This is especially important when sending bulk email (high volume email) as it helps maintain the deliverability and reputation of your email campaigns.”
The new email rules are aimed at people who send more than 5,000 emails per day to Gmail addresses.
Other companies have also spoken out about the changes, with Yahoo singing from the same hymn sheet as Google.
