Website Form Emails Not Working?
None of your website's forms are sending email notifications anymore. It's a site-wide problem.
Find Out What's Wrong in 60 Seconds
Our free scan loads your site in a real browser and checks for this exact issue.
When all your forms stop sending emails at once, you're dealing with a systemic issue. It's not a problem with one form's configuration—something fundamental about how your site sends email is broken.
This kind of site-wide failure often happens after hosting changes, server updates, or when email services expire. The good news is that fixing one thing should fix all your forms.
The bad news is that until you fix it, you're completely blind to every contact attempt, quote request, and inquiry your website receives.
Common Symptoms
- • Multiple forms on your site aren't sending emails
- • Email notifications stopped working site-wide
- • The problem started after a hosting or server change
- • All forms submit but no emails arrive
- • Email functionality was working, then suddenly stopped
- • Test emails from the server also fail
Why This Happens
1. Server Email Function Disabled
Your hosting provider may have disabled the mail() function or outgoing email entirely. This is common after abuse reports or policy changes.
2. SMTP Plugin or Service Expired
If your site uses SMTP for email delivery, the plugin license might have expired, the service subscription ended, or API credentials were revoked.
3. Hosting Migration Broke Email
Moving to a new host often requires reconfiguring email settings. Default server email might not work, and SMTP credentials from the old host won't transfer.
4. PHP or Server Update Changed Behavior
Server updates can change how email functions work, what ports are available, or what libraries are installed. Previously working code might now fail.
5. IP or Domain Blacklisted
If your server's IP or domain ended up on email blacklists, outgoing emails will be rejected by receiving servers across the board.
Quick Diagnostic Checklist
Try these steps to narrow down the problem:
-
1
Test server email function
Use a simple PHP mail test or your CMS's email test feature to check if the server can send email at all.
-
2
Check hosting provider email status
Contact your host or check their status page for any email-related restrictions or outages.
-
3
Verify SMTP plugin is active and configured
Check that your SMTP plugin is still active, licensed, and has valid credentials.
-
4
Check for recent changes
Identify any hosting changes, updates, or configuration changes that coincide with when email stopped working.
-
5
Test sending to different addresses
Try sending to various providers (Gmail, Outlook, etc.) to see if the issue is universal.
-
6
Check blacklist status
Use tools like MXToolbox to check if your IP or domain is on email blacklists.
When to Stop Debugging Manually
Site-wide email failures require server-level investigation:
- — Server configuration and capabilities
- — Hosting provider policies and restrictions
- — Email service status and credentials
- — DNS and authentication records
This is typically a hosting or infrastructure issue, not a form issue.
