Email validation for a form should at most look for

  • at least one character
  • followed by @
  • followed by at least one character
  • followed by .
  • followed by at least two characters

Sending an email can take a few minutes. Form validation is instant.

Which would still not be perfect because "foo@bar", "foo@[123.123.123.123]" and "๐Ÿ’ฉ @[IPv6 :::1]" are all technically valid email addresses.

It looks like the only validation that doesn't block something valid pretty much would start and end at "It has at least one @ symbol, and something on both sides".
