i have very kindly been invited to a work buddy's evening reception to celebrate their wedding. However i cannot go due to prior personal commitments. Any ideas where i can find a suitable RSVP template?
so just write a nice letter thanking them, explain why you cannot come, but would have loved to, and wish them well.
you could send a congratulations card with it.
a template for a friends wedding is a bit formal, especially as you are not going - might seem ungrateful and cold
You should reply with the same formality as that of the invitation. If the invitation was very formal ( is that why you are asking about a template?).....
Mad Mondeo thanks Adam (Arcadia) & Eve (Eden) for their very kind invitation to an evening reception to celebrate their wedding. He very much regrets that he is unable to attend due to prior personal commitments.
Keep the wording / tone the same as that on the invitation. If the bridegroom is a work buddy you can always tell him personally why it is that you can't go.
