White-glove migration

Live in under an hour.
Every time.

Our migration engineers run the playbook end-to-end. You don't touch DNS or DKIM — we do. Average enterprise migration: 45 minutes. Worst case: one morning.

01
Audit your current setup~10 min

We map every sending domain, IP, DKIM key, and webhook endpoint. You share read-only dashboard access — nothing changes yet.

02
Configure in parallel~20 min

Sendbound is provisioned and tested alongside your live provider. DNS, DKIM, SPF, and templates are verified before any traffic moves.

03
Cut over and go live~15 min

Traffic is routed to Sendbound with a single config change. Your previous provider stays warm for 48 hours as a fallback. Zero downtime.

Total migration time: under 1 hour for most enterprise customers.
