writing flexible regex expressions

I am trying to write a program that reads text from screenshots and then identifies various PII from it. Using pytesseract to read in the text, I am trying to write regex for urls, email IDs etc. Here is an example of a function which takes in a string and returns True email IDs and False otherwise:

def email_regex(text):
    pattern = compile(r"\A[a-z0-9!#$%&'*+/=?^_‘{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_‘{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?")
    return bool(pattern.match(text))

This function works well for all email IDs in a proper format([email protected]), but since the input to the function is text read in from pytesseract, the text is not guaranteed to be properly formatted. My function returns False for abc@xyzdd. I'm running into the same issues with URL regex,domain name regex etc. Is there a way to make my regex expressions more robust to reading in errors from pytesseract?

I have tried following the accepted solution to this answer, but that leads to the regex functions returning True for random words as well. Any help to resolve this would be greatly appreciated.

EDIT :- Here are my url and domain regexs, where I'm running into the same problem as my email regex. Any help with these will be very useful for me.

    pattern = compile(r'\b(((([a-zA-Z0-9])|([a-zA-Z0-9][a-zA-Z0-9\-]{0,86} 
    [a-zA-Z0-9]))\.(([a-zA-Z0-9])|([a-zA-Z0-9][a-zA-Z0-9\-]{0,73}[a-zA-Z0-9]))\.(([a-zA-Z0-9]{2,12}\.[a-zA-Z0-9]{2,12})|([a-zA-Z0-9]{2,25})))|((([a-zA-Z0-9])|([a-zA-Z0-9][a-zA-Z0-9\-]{0,162}[a-zA-Z0-9]))\.(([a-zA-Z0-9]{2,12}\.[a-zA-Z0-9]{2,12})|([a-zA-Z0-9]{2,25}))))\b', re.IGNORECASE)
    return pattern.match(text)```


  def url_regex(text):
    pattern = compile(r'(http|https://)?:(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\(\),]|(?:%[0-9a-fA-F][0-9a-fA-F])+)', re.IGNORECASE)
    return pattern.match(text)
