It's absolutely fine, dry it well and it burns like any soft wood.
All depends on how much storage you have. I have some piles of willow, not the best heat output but dried well it burns fine....so use it at the beginning and end of the season when you don't need as much heat. The other day the Mrs wanted the fire lighting as it was raining and her mate was coming round, so no point burning kiln dried oak....so it's time for cheap soft wood. If been burning my lesser woods for the last 2 months.
If you have room for it then split it and dry it
