It sounds like your hosting provider has disabled PHP’s mail() function, which contact form plugins use. It’s the same function that is used by WordPress to send you comment notifications, or notifications about new users registering on your site.
This is a common safeguard employed by hosting providers when they suspect that another customer on the same server is sending spam emails directly from the server.
Another alternative is that PHP’s mail() function is still active, but spammer activity from the server has already caused any email sent from it to be blacklisted. This would result in the emails being sent, but never received by any email address with basic anti-spam capabilities.
You can check this by leaving a comment on your site and checking if you receive an email. Another alternative would be to use the Health Check plugin and sending yourself a test email from the plugin’s Tools tab to see if it works.
If you didn’t receive a test email, you could try using an SMTP plugin to configure your WordPress site to use your email’s outgoing mail server instead of PHP’s mail() function.
I use a SMTP plugin but messages generated from the site is not received by the site emails.
I have other sites on the same server and they all work well
What SMTP plugin are you using?
The one by wpforms (can’t recall the name)
Now notification are sent to my Gmail email
Ok, I recommend reporting the issue at https://wordpress.org/support/plugin/wp-mail-smtp so the plugin’s developers and support community can help you with this.
Its not coming from the plugin because other users and even test mail from the plugin are received by others. except the domain emails editor/contact @ healthable.org.
comments, new post submission mails are not received at contact @ healthable.org
If you’re using the SMTP plugin, it is responsible for sending _all_ emails from your site, so I still recommend following up with them to find out why that’s not working out.
