Imean, theres not much that needs concluding - the text for Sending explicitly allows for cross-planar communication, but the other party is not compelled in any way to answer, so deities or other beings will probably just ignore any unsolicited Sendings. Contact Other Plane, meanwhile, does entitle the caster to answers, which is a significant difference.
