Hi I am super late to the party but just had the same issue. I figured out that the contact form submission goes to our mail. However we must select the All mail option instead of inbox. It is not in the junk mail. Once you go to all mail category, you must categorize the sender. It will then move all emails to inbox automatically. If you are using an iPhone, you would slide left on the email, press more, select categorize sender, and place in inbox or primary. I hope this helps. I will also post the link to my new business. I would appreciate any support https://seekingthekingdom.myshopify.com. Have a blessed day! 
Topic summary
A Shopify store owner reports their contact form has never worked—test emails from the admin panel arrive successfully, but customer submissions from the live contact page never reach their inbox, raising concerns about lost business opportunities.
Troubleshooting suggestions provided include:
- Verifying email addresses in Settings > Notifications
- Checking spam/junk folders
- Removing and re-adding recipient email addresses in notification settings
- Sending test notifications from Shopify admin
- Reviewing theme files (contact.liquid) to ensure proper form setup with correct action attributes and POST method
- Using browser developer tools to inspect form data submission
- Contacting the email host provider about potential filtering issues
Outcomes:
- The original poster tried standard troubleshooting steps without success and ultimately removed the built-in contact form, replacing it with direct email and Facebook Messenger links—which successfully generated customer contact.
- Another affected user resolved the issue by installing a third-party contact form app (Storeify).
- One late contributor discovered their contact form emails were arriving in the “All Mail” folder rather than the inbox, requiring manual sender categorization to route future messages correctly.
The discussion remains unresolved for the native Shopify contact form, with workarounds implemented instead.
