Hi@akhtar,
You can use the Email plugin in Logstash. It allows you to connect your email account with the help of SMTP, IMAP, etc server. I have attached one example below for your reference.
output {
email {
  to => "xyz@gmail.com"
  body => "Message: This is Nadeem"
  address => "smtp.gmail.com"
  port => 587
  username => "abc@gmail.com"
  password => "password"
  use_tls => true
}
}
