I'll message you later to reschedule.
'Ridefinire' — ri-de-fi-NI-re. Stress on the fourth syllable. Clear, even syllables.
Use to end a cancellation conversation positively by committing to a follow-up. This phrase shows you value the relationship and intend to keep the plans — just not today.
'Ti mando un messaggio' means 'I'll send you a message'. 'Ridefinire' means to redefine or reschedule. This forward-looking phrase transforms a cancellation into a temporary delay, which is much more relationship-positive.
Ti scrivo appena sono libero/a.
I'll write to you as soon as I'm free.
More casual — 'scrivere' is used informally for sending messages
Riorganizziamo al più presto.
Let's reorganise as soon as possible.
Uses 'noi' (we) form — collaborative and relationship-positive
Fammi sapere quando sei disponibile.
Let me know when you're available.
Passes the initiative to the other person — generous gesture
Following through on the promise to reschedule is crucial in Italian social culture. If you say you'll message to set a new date and then don't, the relationship can cool significantly.
