22 Oct What Should You Check When Your Website Contact Forms Stop Sending Emails?

Why Contact Form Emails May Stop Arriving

Contact forms are vital communication channels on most business websites. When they stop sending emails, it can disrupt leads, customer inquiries, and sales opportunities. Several technical or configuration issues can cause this problem. Understanding what to check first helps to quickly identify and fix the root cause.

Common Causes of Contact Form Email Failures

• Incorrect or Missing SMTP Configuration: Contact forms often rely on SMTP settings to send email. If these settings change or are missing, emails won’t be delivered.
• Spam Filtering and Email Deliverability Issues: Emails may be sent but end up in spam folders or blocked by the recipient’s email server due to missing SPF, DKIM, or DMARC authentication.
• Plugin or Theme Conflicts in WordPress: Updates or incompatibility among WordPress plugins, particularly contact form plugins, may cause failures.
• Hosting Server Restrictions: Some hosting providers limit the number of emails sent per hour or block the PHP mail function, affecting email sending.
• Changed or Expired Email Credentials: Password expired for the email account used to send messages or changes in account credentials.
• Website or Server Errors: Configuration errors, PHP errors, or server downtime can disrupt form processing.

Step-by-Step Checklist To Troubleshoot Contact Form Email Problems

1. Verify Contact Form Settings

• Check the email address set to receive form submissions is correct and active.
• Ensure the ‘From’ email address uses a domain email matching your website domain to avoid spam filters.
• Review any recent changes to the contact form plugin or configuration.

2. Test SMTP Configuration

• If your form uses SMTP, confirm SMTP server, port, username, and password are accurate.
• Consider setting up a dedicated SMTP plugin in WordPress for improved reliability.
• Perform a test email send from your website or SMTP plugin’s test feature.

3. Check Email Deliverability Settings

• Verify your domain’s SPF, DKIM, and DMARC DNS records are configured properly to authorize your website to send emails.
• Use online tools to check if your email domain is blacklisted.
• Ask recipients to check spam or junk folders.

4. Review Hosting Server and PHP Mail Function

• Confirm your hosting provider allows sending emails from the server and has not implemented restrictions recently.
• Check if the PHP mail function is enabled and functioning as contact forms often rely on it.
• Look for server errors in your hosting control panel or logs that could affect email sending.

5. Test with Default WordPress Theme and Plugins Disabled

• Temporarily switch to a default WordPress theme, such as Twenty Twenty-One, to exclude theme-related issues.
• Deactivate all other plugins except the contact form plugin to rule out plugin conflicts.
• Test sending emails again.

6. Review Email Account Credentials and Quotas

• If you use a mailbox to send emails via SMTP, check that its password hasn’t changed or expired.
• Confirm the email account’s inbox quota is not full, which could block incoming emails.

How Troubleshooting Influences Project Costs

Troubleshooting email issues may be straightforward or complex, impacting the service cost. Simple settings adjustments or SMTP plugin configuration are usually quick fixes. However, in complex cases, such as server misconfiguration, authentication records, or hosting limitations, a thorough time-consuming investigation and implementation are required.

Preparing detailed information about your hosting environment, email setup, and recent changes will help an expert diagnose issues efficiently.

Prevention and Post-Fix Recommendations

• Always keep backups of your website and configurations before major updates.
• Regularly test your contact forms after updates or hosting changes.
• Use SMTP plugins with logging to monitor email sending status.
• Maintain accurate SPF, DKIM, and DMARC records for your domain to improve email deliverability.
• Schedule regular maintenance checks including plugin, theme, and WordPress core updates to reduce conflicts.
