Send Convertful leads straight to Customer.io

Build pop-ups, bars and inline forms in Convertful and every new subscriber lands in Customer.io with the tags and fields you choose, so you never export a CSV. On Growth and above, widgets can also read Customer.io tags to decide who sees what.

Fields and tags

Customer.io fields and tags, mapped once

Choose the list, tags and custom fields each form writes to. Each form field lands in the Customer.io field you pick, so you can segment and personalise without tidying anything up.

With Customer.io the sync also runs the other way. From Starter, widgets can read fields to greet people by name, and from Growth they can use Customer.io tags to decide who sees what.

Targeting

Choose who sees each form, and when

Show a form on exit intent, after a delay or a scroll, or when someone clicks a link. Narrow it down by page, visit number, country, device and referral source, and keep it away from people who already subscribed.

  • Country, region and city targeting on every plan.
  • A/B test two versions and keep the one that brings more subscribers (Starter and above).

FAQ

Questions about the Customer.io integration

Does the Customer.io integration sync both ways?

Yes. Convertful writes new subscribers, tags and fields to Customer.io, and it can read fields back to personalise the text (Starter and above) and use tags to decide which widget a visitor sees (Growth and above).

How do I connect Customer.io?

Add the account in Convertful’s integration settings, with one click or an API key depending on the tool, pick the list or tags for each form, and publish. The integration docs show each step.

Is the integration included in every plan?

Yes. Native integrations are included on every plan, including the free trial. Two-way sync of fields is on Starter and above, and using CRM tags and fields as display rules starts on Growth.

Can leads also go to a second tool?

Yes. A form can send to several integrations at once, post to a webhook, or reach any other app through Zapier, n8n or Integrately.
