so people can simply skip the question if empty and/or non properly answered.
This contradicts the validation. Why do a validation if the respondent is free to enter something wrong?
To enter your own text, use the "question validation equation" and the "question validation tip" in "Logic"
Here you have to use "regexMatch(pattern,question)"
And here you can allow to proceed if left empty
Like:
is_empty(question) or regexMatch(pattern,question)
If you only want to give a hint if the email is not correct without any consequences, insert it either in your question text or in the help text.
Like
{if(!regexMatch(pattern,question),'<span style="color:red">This email is not correct</span>','')}
or something like that.
