What this tool estimates (and what it doesn’t)

  • Time: export/import, field mapping, consent, templates, flows, and QA.
  • Risk: tracking gaps, consent drift (EU), domain/auth issues, and flow parity misses.
  • Checklist: a practical “do this in order” plan you can delegate.

Tip: treat migration like a release. Keep the old platform sending only if you can avoid double-sending to the same subscriber.

Migration shortcuts that usually backfire

  • Importing contacts without clear consent fields and source.
  • Rebuilding flows before purchase + browse events are verified.
  • Copying templates without checking link tracking and UTM rules.
  • Going live without a 7-day deliverability + revenue QA plan.

How accurate is this output?

It’s a planning estimator based on typical ecommerce migrations. Your real timeline depends on list cleanliness, flow parity, and integrations. Use the checklist to validate scope quickly.

What inputs do I need before I start?

Subscriber count, number of segments, core templates, key automations, and a quick inventory of integrations. If you don’t know exact counts, use conservative estimates and regenerate.

Does this work for EU/GDPR?

Yes—make consent fields and proof-of-consent a first-class step. Don’t “merge” opt-in statuses blindly. Validate SMS consent separately and document your lawful basis.

How do I implement this in Omnisend?

Start with tracking and consent mapping, import a small test batch, verify events, then rebuild flows in priority order: welcome → abandoned cart → post-purchase → browse/cart retargeting.

Is the Omnisend migration estimator free?

Yes. The Omnisend migration estimator is free to use. If you start Omnisend via our links, it supports ongoing tool development.
