    Basta copiar e colar o regex e-mail abaixo para o idioma de sua escolha. Observe que não há nenhum regex e-mail perfeito, daí os 99,99%.

    Regex E-mail Geral (RFC 5322 Padrão oficial)
    Código:
    (?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])

    Python
    Código:
    r"(^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$)"

    Javascript
    Código:
    /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/

    HTML5
    Código:
    <input type="email" placeholder="Enter your email" />
    No caso de você se perguntar, abaixo está o regex usado em type = "email" do W3C:
    Código:
    /^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/

    Swift (Somente Regex)
    Código:
    [A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}

    Swift (Regex usado em uma função)
    Código:
    let emailRegex = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"
     return NSPredicate(format: "SELF MATCHES %@", emailRegex).evaluateWithObject(candidate)
    }

     or email like '%..%' -- Cannot have two periods in a row
     or email like '%@%@%' -- Cannot have two @ anywhere
     or email like '%.@%' or email like '%@.%' -- Cannot have @ and . next to each other
