Well you're showing the dialog on spawn without any conditions. Make a global boolean to check if the player has an account or not:

pawn Код:

new
    bool:g_bRegistered[ MAX_PLAYERS ]
;

Then set it to true when a player registers:

pawn Код:

g_bRegistered[ playerid ] = true;

Then on spawn add a condition to check if it's set to true, and if it is; show the e-mail dialog:

pawn Код:

if( g_bRegistered[ playerid ] )
{
    // show dialog
}
