Build a campaign your team can actually run.
Updates, regional versions and approvals are part of a campaign. I’d plan for them early, so the creative fits the team that will keep it moving.

Map the whole journey
What follows the announcement? Map the main moments, from the first response to the next action. Give each piece a clear job.
Be realistic about who will keep it moving
Agree who supplies information, reviews it and releases the work. Check they have time for it, especially when regional or partner teams are involved.
Choose a sensible way to maintain it
Will updates be manual or automated? A short campaign and an ongoing programme may need different tools. Check what already exists before commissioning something bespoke.
Agree the core before creating every version
Approve a representative piece before extending it. Test the difficult variations early, and keep feedback together so everyone is discussing the same version.
Leave room for changes you can predict
Dates move and translations need space. Agree what your team can edit, what needs design support and how new requests affect the scope and timing.
