Who Must Comply
Google and Yahoo's bulk sender requirements apply to senders who send 5,000+ emails per day to Gmail or Yahoo addresses.
| Sender type | Requirement |
|---|---|
| Bulk senders (5,000+/day) | Full compliance required |
| Small senders (under 5,000/day) | Best practices recommended |
| Transactional senders | Authentication required |
| Marketing senders | Full compliance required |
Requirement 1: Email Authentication
SPF (Sender Policy Framework)
What it is: A DNS record listing which IPs can send email for your domain.
Why it's required: Prevents spoofing and verifies your sending servers.
How to set it up:
- Get your SPF record from your email platform.
- Add it to your DNS as a TXT record.
- Verify with a DNS lookup tool.
Example:
v=spf1 include:your-email-provider.com ~all
DKIM (DomainKeys Identified Mail)
What it is: A cryptographic signature verifying email integrity.
Why it's required: Proves emails weren't tampered with.
How to set it up:
- Get your DKIM record from your email platform.
- Add it to your DNS as a TXT record.
- Enable DKIM signing in your platform.
DMARC (Domain-based Message Authentication)
What it is: A policy telling receiving servers what to do with unauthenticated email.
Why it's required: Google and Yahoo require DMARC with p=reject or p=quarantine for bulk senders.
How to set it up:
- Start with
p=noneto monitor. - Review reports for 2-4 weeks.
- Move to
p=quarantine, thenp=reject.
Example:
v=DMARC1; p=reject; rua=mailto:dmarc@yourdomain.com
Requirement 2: One-Click Unsubscribe
What It Is
Google and Yahoo require bulk senders to support one-click unsubscribe per RFC 8058 — recipients can unsubscribe with a single click, no login required.
How It Works
- Your email includes a
List-Unsubscribe-Post: List-Unsubscribe=One-Clickheader. - The recipient clicks "Unsubscribe" in Gmail/Yahoo.
- Gmail/Yahoo sends an HTTP POST to your unsubscribe URL.
- The recipient is unsubscribed immediately.
The Headers
List-Unsubscribe: <https://yourdomain.com/unsubscribe?token=abc123>
List-Unsubscribe-Post: List-Unsubscribe=One-Click
How to Set It Up
- Use an email platform that supports RFC 8058 (like MisarMail).
- Ensure your unsubscribe URL processes POST requests.
- Unsubscribe the recipient within 24 hours.
- Test with Gmail and Yahoo.
Requirement 3: Spam Rate Limits
The Limit
Google and Yahoo require bulk senders to keep spam complaint rates under 0.3% (3 complaints per 1,000 emails).
| Spam rate | Status |
|---|---|
| Under 0.1% | Excellent |
| 0.1-0.3% | Acceptable |
| Above 0.3% | Non-compliant (filtered) |
How to Monitor
- Use Google Postmaster Tools for Gmail spam rates.
- Use Yahoo Sender Hub for Yahoo spam rates.
- Monitor complaint feedback loops (FBLs).
How to Reduce Complaints
- Use confirmed opt-in (double opt-in).
- Send relevant, expected content.
- Make unsubscribing easy (one-click).
- Segment your list.
- Prune inactive subscribers.
Requirement 4: Valid From Headers
What It Is
Bulk senders must use a valid, non-spoofed From header.
Requirements
| Element | Requirement |
|---|---|
| From address | Real, monitored address |
| From name | Recognizable brand |
| Reply-to | Monitored address |
| Domain | Your authenticated domain |
Common Mistakes
- Using a free email address (gmail.com, yahoo.com) as From
- Spoofing another brand's domain
- No reply-to address
- From domain not matching SPF/DKIM
Requirement 5: Additional Best Practices
Recommended (Not Required)
| Practice | Why |
|---|---|
| Warm up new domains | Build reputation gradually |
| Send consistently | Avoid reputation decay |
| Clean your list | Reduce bounces and complaints |
| Use a custom tracking domain | Improve link reputation |
| Monitor deliverability | Catch issues early |
| Use BIMI | Display your logo in Gmail |
