'autosender' originates from Greek, specifically the word 'autos' (Greek 'αὐτός'), and English 'sender' (from the verb 'send'). 'autos' meant 'self' and 'send' (from Old English 'sendan') meant 'to put/send'.

'autos-' (from Greek 'autos') entered English as a productive prefix via Latin and Modern usage; 'send' comes from Old English 'sendan', which produced the agent noun 'sender' in Modern English. These elements were compounded in recent English usage to form 'autosender' (modern compound formation).

Initially the elements meant 'self' (autos-) and 'one who sends' (sender); over time the compound evolved into its current specialized sense of 'an automated system or tool that sends messages or items without manual intervention.'
