Customer.io checklist

Bring these questions to every demo

Ask vendors to show the workflow live, not just describe it.

  • 1Match best-for scenariosYour motion should resemble who the product serves well.
  • 2Prove the email loopNon-admin list → outreach → CRM evidence.
  • 3Confirm contacts and send limitsMust-haves on a real package before you call it a bargain.

Frequently asked questions

  • Can we decide from a demo alone?

    No. Require non-admin proof of list → outreach → CRM logging on the package you will actually buy.

  • What if sends/contacts look cheap but seats are expensive?

    Model the constraint you will hit first. Many teams exhaust sends/contacts before seats — confirm both on the pricing page.

  • When should we walk away?

    When fit, trial proof, or written packaging fails. Keeping looking is cheaper than forcing Customer.io into the wrong motion.
