Allungare o accorciare gli URL

Capita a tutti di inviare delle email in cui vengono incollati URL talmente lunghi che vanno a capo su più righe. Può accadere che il nostro client di posta sia sufficientemente evoluto per capire che non deve spezzare gli URL, ma non è detto che il nostro desiderio si avveri. Infatti il destinatario, non accorgendosi dell'URL spezzato, quando cliccherà su di esso arriverà a una "pagina non trovata": per lui magari potrà essere una piccola perdita di tempo, per noi potrebbe anche essere un importante click perso. Un'ottima alternativa per evitare questo tipo di inconveniente è quella di… accorciare l'URL.

allungato diventa così (1500 caratteri!):
