BCC not working

Hello.

We have been unable to reproduce the issue you mention using the latest version of our plugin.
Have you tried contacting the authors of the plugins you mention?

Thank you,
SendGrid

Should I be able to test the BCC feature of your plugin by using the “Sendgrid Test” form in wp-admin and filling out the form and then doing “BCC: [email protected]” (without the quotes)?

Hello.

You can add the BCC address in the test form from the plugin settings page, as you can see in this screenshot: https://ps.w.org/sendgrid-email-delivery-simplified/assets/screenshot-5.png?rev=1639690
Let us know if it works from the test form.

Thank you,
SendGrid
