Hello

I have a field from a csv file called email, this field contains a string like this: `mailtio:user@domain.tld`  
I'm trying to remove "mailto:" as first step, then, copying field to a temp. one split the result into two new fields "user" and "provider"

An approach to reach this is something like:

```
		 mutate {copy => { "email" => "email_tmp" }}
		 mutate{
			split => {"email_tmp" => "@"}
				add_field => ["user", "%{[email_tmp][0]}"]
				add_field => ["provider","%{[email_tmp[1]}"]
			}

```

But its not working and I have no clue why (yes, I'm using verbose to see the logs, no luck).  
What m ' doing wrong?  
Thanks in advance.

The second field reference is invalid (it is missing a bracket). Try

```
mutate { copy => { "email" => "[@metadata][email_tmp]" } }
mutate { gsub => ["[@metadata][email_tmp]", "^mailto:", "" ] }
mutate {
    split => { "[@metadata][email_tmp]" => "@" }
    add_field => {
        "user" => "%{[@metadata][email_tmp][0]}"]
        "provider" => "%{[@metadata][email_tmp][1]}"]
    }
}

```

I was waiting for you! Thanks, its working!!!! But it needs two claudators

```
mutate { copy => { "email" => "[@metadata][email_tmp]" } }
mutate { gsub => ["[@metadata][email_tmp]", "^mailto:", "" ] }
mutate {
    split => { "[@metadata][email_tmp]" => "@" }
    add_field => {
        "user" => "[%{[@metadata][email_tmp][0]}"]
        "provider" => ["%{[@metadata][email_tmp][1]}"]
    }
}

```

Again, thanks!

Sorry, that should have been

```
    "user" => "%{[@metadata][email_tmp][0]}"
    "provider" => "%{[@metadata][email_tmp][1]}"

```

You do not need the brackets around the string
