{ "data": { "id": "swp_01HZX0SW1A2B3C4D5E6F7G8H", "type": "premium", "domain_id": "dom_01HZX0D01A2B3C4D5E6F7G8H", "replacement_domain": "acme-fresh.com", "status": "created", "created_at": "2026-05-08T12:00:00Z" } }
Standard vs Premium. standard retires the old domain immediately — fine when you can absorb a brief sending pause. premium keeps the old domain warm for 14 days alongside the new one for a smoother handoff with no sending interruption.Premium swaps are available on Microsoft domains only, count against a per-tier quota (Base 20% / Premium 30% / VIP 40% / VIP+ 60% of active Microsoft inboxes), and each domain has a 30-day cooldown between premium swaps.For renaming the people on inboxes without changing the domain, use POST /swaps/user_names instead.
