^[^@]+@[-a-z0-9.]+$
^ – match start of string
[^@]+ – match one or more characters that aren’t an @
@ – match an @
[-a-z0-9.]+ – match one or more characters from the set ‘-‘, lower case ‘a’-‘z’, the digits ‘0’-‘9’, ‘.’
$ – match end of string
So, match any string that consists of some characters that aren’t ‘@’, followed by ‘@’, followed by some number of lower case letters / digits / dashes / full stops.
