This is an example of a typical email address format john_doe18@yahoo.com.

Next example is an email address with plus sign mary.smith+socials@gmail.com.

Now let's test two emails with a country code top-level domain like george-wilson82@mail.co.uk and ram.patel94@yahoo.co.id.

How about an obfuscated id like z3daxdlnbp1hyqk26mjjffu@protonmail.com.
