Asendia ia a parcel/post service owned jointly by French and Swiss post offices.
But what does the name allude to/sound like?
1. "I send you"?
2. "Ascend" (with a "c")? Which is a bit inappropriate, you don't just want your post to go up without coming down again. Unless your addressee lives on a cloud or a high mountain.
3. "Arse end, yeah"?
