Hello draspall,
1. To better assist you, could you kindly test the functionality with default WordPress themes such as TwentyTwenty or WooCommerce Storefront? This will help us determine whether the issue stems from our theme or elsewhere.
2. Here are some common issues and suggestions to troubleshoot the problem:
+ Email service provider: Verify that your email service provider is properly configured and functioning correctly. Make sure your server is not blacklisted and that there are no email delivery issues from your side.
+ SMTP configuration: Consider setting up Simple Mail Transfer Protocol (SMTP) to send emails. This method ensures that emails are sent using a dedicated email server and can help improve deliverability. You can use plugins like WP Mail SMTP or Easy WP SMTP to configure SMTP settings.
+ Email logs: Check if your hosting provider offers email logging. This feature can help you track the emails sent from your website and identify any potential issues or errors.
+ Email server configuration: Verify with your hosting provider if there are any specific requirements or restrictions for sending emails from your server. They might have certain limitations or configurations that need to be addressed.
+ Test with different email addresses: Try using different email addresses (including external email providers like Gmail or Yahoo) to test if the issue is specific to the client’s email address or applies to all recipients.
