Why is my email to customer support undeliverable?

Has anyone come across a situation where you try and contact the website or customer support from the company you ordered from and your email comes back undeliverable? I have been trying to contact this business to get update on an order I purchased Nov. 1st. I have no way of contacting them. What should I do
thanks Jo

  1. That is unusual, but possibly their email which is hosted on 3rd party email platform is misconfigured.

  2. Contact Shopify merchant support, possibly they can notify the store owner about the mailing issue or provide you with an alternative contact option.

  3. If you run out of the option of reaching the store support, then you can report a problem with the store.
