Concerns about Potential iPhone Hacking After Clicking on a Suspicious Email Link

A little while ago, I received a strange email from an internet company, and out of curiosity, I clicked on the link provided. However, the link led me to an error page with nothing on it except for an error message in the top left corner. Concerned about the possibility of being scammed or having my data compromised, I immediately turned off my data and switched my phone to airplane mode. Now, I'm seeking assistance or guidance on how to determine if my phone has been hacked.

regards.
