What happens if Mailchimp changes their API after we go live?
Our SRE team monitors Mailchimp change announcements and rolls compatibility updates inside our maintenance retainer. If a breaking change ships, we own the migration; you don't pay extra to stay current and you don't field calls from the vendor.
Does it work with our existing Mailchimp licenses?
Yes — the adapter rides on top of your existing Mailchimp subscription. We use service-principal or OAuth M2M credentials so the integration never burns a named-user seat and never pushes you into a higher tier.
Will this break our existing reports?
No. The adapter writes through a versioned schema layer with full lineage. Existing reports, BI extracts and Excel pivot-tables keep working unchanged while new fields and new objects are added behind the scenes for the Mailchimp surface.
How is data security handled?
Tokens and credentials live inside a hardware-backed secret store with audit logging on every read. The Mailchimp adapter runs on isolated workers with deny-by-default egress, and every message is replayable from a tamper-evident journal for downstream forensics.
Can the Mailchimp adapter handle our custom fields?
On first connection the adapter discovers every custom field, custom object and custom workflow inside your Mailchimp tenant and presents them as first-class mappings — you decide which to mirror, which to ignore, and which to enrich.
How long does the Mailchimp integration take to ship?
Our standard window is thirty days from signed scope to live Mailchimp adapter in production, plus a one-week monitored stabilization phase. For Tucson, Arizona, that includes a sandbox loop with your team, parallel-run reconciliation, and a documented runbook handed to your operations lead.
