Most probably you have a plugin that misbehaves. Some bring their own copy of phpmailer classes and / or override standard wordpress wp_mail() function.

To diagnose, you can try temporarily deactivate some plugins just to see whether HGK SMTP will be able to send test emails without potential interference. Then activate them back.

I understand that if you have high traffic site, that may be a bad idea, this is why I ask for the screenshot. Actually I just wanted a list of your plugins – (unless you have dozens ?? I could install the same set on my test wordpress box to see what’s going on.

Well, we can try to dig a little deeper ??

What version of WP do you use?
What operating system it is run on?
Do you use a web hosting provider?

Can you also send a screenshot of your WordPress “Manage Plugins” page?
Send it by email – here is the page with support email address: https://www.ihagaki.com/contact-us/

Once I have those details, I’ll see what I can do.

Thanks!

1. Please make sure you have no other plugins with similar functionality active. If necessary deactivate them.
2. Use exactly the following settings:
SMTP server address: smtp.gmail.com
Use SSL connection: checked
SMTP server port: 465
3. Fill in your specific account details:
SMTP username: [email protected]
SMTP password: you_gmail_password
4. Clear “Sender e-mail” and “Sender Name” entries.
5. Save the changes.

6. Send a test e-mail.

Please note that if you are sending to your own gmail account (the one in step #3 above), it won’t appear in your inbox – check your sent folder instead. This is a standard gmail behavior.

Can you drop a line back with the results?

Thanks!
