Email providers have always published sender guidelines to protect deliverability and reduce spam. In 2024, both Gmail and Yahoo raised the bar by making authentication mandatory for bulk senders. If you send at scale to Gmail or Yahoo addresses, these rules apply to you.
What are the changes?
From February 2024, both providers require all bulk senders to:
- Set up SPF and DKIM authentication for your sending domain.
- Set up DMARC authentication for your sending domain.
- Support one-click unsubscribe, with a clearly visible unsubscribe link in the message body.
These sit on top of existing requirements that already apply to anyone sending to Gmail or Yahoo inboxes:
- Message format must comply with the RFC 5322 standard.
- Spam rate must stay at 0.3% or lower.
- Sending domains and IP addresses must have valid PTR records.
- The From: header must not impersonate Gmail or Yahoo.
For the full detail, see Gmail's sender guidelines and Yahoo's Best Practices.
Why are things changing?
The core goal is reducing email fraud and spam. DMARC is the centrepiece of that effort. It protects your domain against phishing and spoofing by telling receiving mail servers what to do with messages that fail authentication checks. When you have DMARC in place, you signal to Gmail and Yahoo that your domain is a legitimate source, which protects both your recipients and your sender reputation.

Frequently asked questions
- Who do the Gmail and Yahoo 2024 bulk sender requirements apply to?
- They apply to anyone sending email at scale to Gmail or Yahoo addresses. If you send bulk or marketing email to these domains, you need SPF, DKIM, and DMARC on your sending domain, plus one-click unsubscribe support in your messages.
- What is DMARC and why does it matter for deliverability?
- DMARC is an email authentication policy that tells receiving mail servers what to do when a message fails SPF or DKIM checks. It protects your domain from being used in phishing and spoofing attacks, and signals to providers like Gmail and Yahoo that your domain is a safe sender.
- What happens if I do not meet these requirements?
- Gmail and Yahoo can rate-limit, mark as spam, or block messages that do not comply. Getting your authentication in order before you hit those limits protects your sender reputation and keeps your emails landing in the inbox.
- Can TouchBasePro help me set up SPF, DKIM, and DMARC?
- Yes. TouchBasePro can walk you through setting up all three, verify that existing configurations are correct, and monitor your authentication results over time. Fill in your details on the linked form to get started.
