"for each" loop exits when sendmail fails

I am sending email to a subset of records satisfying a condition. The problem is that occasionally a record has an invalid email addresses and the "for each" loop exits in this case. This is a problem because everyone in my records needs to get that message. How do I make "for each" continue to the next record without exiting?

for each X in Registrar [SEND_EMAIL == 2]
{
    sendmail
    (
        To       : X.Email_Address
        From     : zoho.adminuserid
        Subject : "Estás invitado a participar en un Experimento"
        Message : "Querido " + X.First_Name + " " + X.Last_Name + ",.. blah.. blah
    )
}
