Propose several times and let a group tick the ones that work for them.
Doodle is the original group poll: you list candidate slots, everyone ticks what suits them, and the winning column becomes obvious without a reply-all thread. It survives because it asks nothing of participants — no account, no app, one visit each. The free version is ad-supported and pushes hard toward the paid calendar-connected booking pages.
