Google Workspace
(Work → Gmail fails, Gmail → work succeeds)
THE FIX (THIS WORKS)
>> Remove Mailgun from SPF (IMPORTANT)
This is the most common fix in your exact situation.
Change SPF to Google-only: v=spf1 include:_spf.google.com ~all
______________________________________
Most common causes (in order of likelihood)
1. Emails are going to Gmail Spam or filtered folders
Even if you don’t see them:
In Gmail
1. Search:
from:@humanconcernusa.org
2. Check Spam, All Mail, Promotions, and Updates
3. If found in Spam:
• Open the email
• Click “Not Spam”
• Click the three dots → “Filter messages like these” → Create filter
• Choose Never send it to Spam
⸻
2. Gmail is blocking or silently rejecting the domain
Gmail may distrust the sending domain if authentication isn’t correct.
Fix (important):
1. Open Gmail Settings
2. Go to Filters and Blocked Addresses
3. Make sure:
• @humanconcernusa.org is NOT blocked
4. Go to See all settings → Accounts and Import
5. Under Send mail as, make sure nothing unusual is set
⸻
3. SPF / DKIM / DMARC issue on humanconcernusa.org (VERY common)
If the domain’s email authentication is misconfigured, Gmail will reject or spam the email without notifying you.
This is the #1 cause when:
• Some recipients receive emails
• Gmail does NOT
How to confirm quickly
Send an email from your work email to:
check-auth@verifier.port25.com
You’ll get a reply showing:
• SPF
• DKIM
• DMARC
If any fail, Gmail may block delivery.
⸻
4. The email server IP is blacklisted
If your work email server is on a spam blacklist, Gmail may refuse delivery.
Signs:
• No bounce-back
• Email “sends” successfully
• Gmail never receives it
You can test by asking:
• Does sending to Outlook / Yahoo work?
• If yes → Gmail-specific blocking
• If no → server reputation issue
⸻
5. Gmail alias / forwarding issue (if used)
If you:
• Forward emails to Gmail
• Use aliases
• Use Google Workspace routing
Then Gmail may be discarding forwarded messages.
Check:
• Settings → Forwarding and POP/IMAP
• Disable forwarding temporarily and test again
⸻
Quick tests to isolate the problem (do these now)
1. Send from work email → another Gmail address (friend or secondary)
2. Send from work email → Outlook.com
3. Reply to an email originating from Gmail (thread reply)
Tell me:
• Which ones arrive
• Which do not
⸻
GoDaddy. Follow exactly these steps.
STEP 1: Log into GoDaddy DNS
1. Go to GoDaddy → My Products
2. Find humanconcernusa.org
3. Click DNS
We’ll check SPF, DKIM, and DMARC.
⸻
STEP 2: FIX SPF (MOST IMPORTANT)
Look for existing SPF records
In Records, find TXT records with:
v=spf1
IMPORTANT RULE
⚠️ You must have ONLY ONE SPF record
⸻
Correct SPF record (Google Workspace)
If you already have one:
• Edit it so it looks like this:
Type: TXT
Host: @
Value:
v=spf1 include:_spf.google.com ~all
TTL: 1 hour
If you have more than one SPF record:
• Merge them into ONE
• Delete the extras
⸻
STEP 3: FIX DKIM (REQUIRED)
In Google Admin:
1. Go to admin.google.com
2. Apps → Google Workspace → Gmail
3. Authenticate email
4. Select domain: humanconcernusa.org
5. Click Generate new record
• Key length: 2048-bit
• Selector: google
Google will give you a TXT record.
⸻
Add DKIM record in GoDaddy
Back in GoDaddy DNS → Add Record:
Type: TXT
Host:
google._domainkey
Value: (paste the long DKIM value from Google)
TTL: 1 hour
➡️ Save it
➡️ Go back to Google Admin and click Start Authentication
Status should say ON.
⸻
STEP 4: ADD DMARC (Highly Recommended)
In GoDaddy DNS → Add Record:
Type: TXT
Host:
_dmarc
Value:
v=DMARC1; p=none; rua=mailto:dmarc@humanconcernusa.org; ruf=mailto:dmarc@humanconcernusa.org; fo=1
TTL: 1 hour
If dmarc@humanconcernusa.org doesn’t exist yet, create it in Google Workspace or temporarily remove the rua/ruf parts.
⸻
STEP 5: WAIT & TEST (VERY IMPORTANT)
⏱️ DNS propagation: 15 minutes – 2 hours (sometimes up to 24)
After 1 hour, test:
1. Send work → Gmail (new email, not reply)
2. Send work →
check-auth@verifier.port25.com
You want:
• SPF: PASS
• DKIM: PASS
• DMARC: PASS / NONE
⸻
STEP 6: Gmail-side safety (1 minute)
On your Gmail account:
1. Search:
from:@humanconcernusa.org
2. If anything appears in Spam:
• Mark Not Spam
• Add sender to Contacts
⸻
WHY THIS WILL FIX IT
• Gmail was silently dropping unauthenticated mail
• Outlook is more forgiving
• Replies worked because Gmail trusted the thread
Once SPF + DKIM are aligned, Gmail must accept your emails.
