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 Peoria, Arizona, that includes a sandbox loop with your team, parallel-run reconciliation, and a documented runbook handed to your operations lead.
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.
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.
What does pricing look like?
Implementation is fixed-fee with a $0-until-live guarantee for Peoria, Arizona. After go-live, the Mailchimp adapter runs on a flat monthly run-rate sized to message volume — no per-API-call gotchas, no per-seat surcharges, and a one-page exit clause.
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.
