Use this code in submitEmail function.

// test values
const email = 'email@test.com'
const emailFoo = ''
const emailEA = 'emailEA@test.com'

const emails_to_send = {email, emailFoo  ,emailEA}
for(const email in emails_to_send){
  if(!emails_to_send[email].match(/^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/g)) delete emails_to_send[email]
}
//     Axios.post("http://localhost:3001/",emails_to_send)
console.log(emails_to_send)

Note: Uncomment the axios.post line while using this code.

Note: Although the code works properly , I think that sending unfilled emails to backend shouldn't be a problem.
