FAQ and Troubleshooting

In short: Quick answers to common questions, plus fixes for the most frequent issues. Use your browser's find to jump to a question.

Getting started

Do I need to install anything?

Flunnel is a Shopify app. Install it from the Shopify App Store and it runs inside your Shopify admin. There is nothing else to download.

Which AI providers can I use?

You bring your own AI provider and key, set on the API key tab in Settings. [CẦN ĐIỀN: danh sách provider được hỗ trợ, ví dụ Google Vertex AI, OpenAI, Anthropic.]

Do I have to connect Klaviyo?

You need Klaviyo to capture opt-ins from your page and to send the email flow. A page can still be published without it, but the email side will not work until Klaviyo is connected. See Settings and Governance.

How much does Flunnel cost?

[CẦN ĐIỀN: giá / gói của Flunnel.] Separately, AI generation is billed to your own provider key, based on the model you choose.

Building and generating

How long does generation take?

Usually more than thirty seconds. The exact time depends on the AI model you chose and how detailed your instructions are.

Can I generate a page in another language?

Yes. Set the target language in the brief and the whole page is written in it. [CẦN ĐIỀN: danh sách ngôn ngữ được hỗ trợ.]

Is there a limit on pages or re-rolls?

[CẦN ĐIỀN: giới hạn số page / số lần re-roll theo từng gói, nếu có.]

The page came out off-topic or aimed at the wrong person

This almost always traces back to the brief. Sharpen these fields and re-generate:

1. Persona and core pain. Make them specific.

2. Anchor phrase. Set the exact promise the page should lead with.

3. Raw facts. Add concrete details to write from.

Quick tip: Re-generate one section at a time instead of the whole page. It is faster and keeps the parts that already work.

Editing and publishing

Where does my published page live?

Publishing creates the page inside your Shopify online store, at the handle you approved when you set up the page. It goes live on your store domain.

Can I change the URL handle after publishing?

[CẦN ĐIỀN: có sửa được handle sau khi publish không, và thao tác thế nào.]

Can I unpublish or delete a page?

[CẦN ĐIỀN: cách unpublish / xóa page.]

Will re-rolling lose my manual edits?

Only if those sections are unlocked. Lock the sections you want to keep before you re-roll, and they are preserved exactly. If something is lost, version history can restore an earlier version. See Editing Your Page.

How long is version history kept?

[CẦN ĐIỀN: thời gian / số version được lưu.]

Emails and Klaviyo

Does Flunnel send the emails?

No. Flunnel writes the emails and syncs them to Klaviyo. Klaviyo sends them, triggered when a visitor opts in on your page. See Email Flows.

My Klaviyo sync failed

Check these in order, on the Klaviyo tab in Settings:

1. The connection status reads Connected.

2. The Private API Key is correct (it starts with pk_).

3. A List ID is set.

4. The Landing Page Subscribe metric has been created.

Can I send SMS too?

[CẦN ĐIỀN: xác nhận có hỗ trợ SMS list ID hay chỉ email.]

Team and security

Is my API key safe?

Yes. Keys are encrypted at rest, and after saving only the last four characters are ever shown. Use Replace to rotate a key.

Can I stop teammates from changing settings?

Yes. Role-based access can make Settings view-only for the roles that should not change it, which protects your keys and house rules. [CẦN ĐIỀN: danh sách role và quyền cụ thể.]
