Using a Gmail Address in Your Contact Form
The two contact forms in your Pub Site work by sending you the message to an email address of your choice.
If you are are using a Gmail address in your contact form and are not receiving your messages, Gmail filters may be why. Please start by checking your spam folders. Also, Gmail has other folders in which it will put incoming emails, including "Social" and "Promotions" as shown in the screen capture below. Look there. Or maybe click on "All Mail" to see if the messages display. Here are the folders you might find. Some are hidden and you have to click on them to expand the list.
If you would like to confirm you are using your correct email address in the form, click on the main Website tab, then hover over the Email Forms tab in the submenu, then select Contact Form. You should enter your email address in the "To:" box.
