WhatsApp with WhatFlow and Web push at a glance
| Consideration | WhatsApp with WhatFlow | Web push |
|---|---|---|
| Best-fit experience | WhatFlow is compelling when the notification is likely to become a sales or support conversation. The inbox is included without seat fees, so the team can act on that interest. | Web push is useful for browser subscribers and can be efficient for short alerts. Its permission and device relationship differs from a phone-based WhatsApp audience. Neither permission should be treated as consent for every other channel. |
| Costs to include | Selected message plan plus applicable Meta delivery fees; no inbox seat fees | Compare the reachable audience and subscriber package for web push with WhatsApp app and delivery costs. A lower cost per send may still be less valuable if the message cannot answer the question preventing purchase. |
| Shopify workflow | Connect Shopify-related WhatsApp outreach with the included team inbox when a returning shopper needs a continuing product conversation. | A return visit and a resolved purchase question are different outcomes. Review the alternative’s actual configured route against the acceptance exercise below. |
| Starting point | Free plan and free-forever theme-matched WhatsApp buttons. All features available; sending allowances differ. | Check whether the destination answers the product question. Keep existing tools that still serve the intended customer task. |
Key takeaways
- Use WhatFlow when a retention message should invite an answer.
- Keep browser visits separate from resolved purchase questions.
- Maintain distinct permission records for web push and WhatsApp.
Start with the customer’s job
A browser notification can bring a shopper back to a product. A WhatsApp message can also open a conversation about whether that product is right for them. The difference matters when an abandoned purchase is caused by uncertainty rather than forgetfulness.
Where each approach helps
For a concrete inventory-alert use case, compare WhatsApp vs email for Shopify back-in-stock alerts.
The practical cost difference
Compare the reachable audience and subscriber package for web push with WhatsApp app and delivery costs. A lower cost per send may still be less valuable if the message cannot answer the question preventing purchase.
When considering an installed shopping app, review WhatsApp vs mobile app push for Shopify brands.
Check the current scope in WhatsApp Business Platform pricing before using this comparison as a purchasing or sending decision.
Why I would use WhatFlow for this workflow
I would use WhatFlow to help a buyer who needs compatibility or delivery advice before returning to purchase. Keep a browser alert when the destination page already answers the question. Record the helpful interaction and resulting order separately, rather than calling every notification click improved retention.
Compare the return visit with the question behind it
For a hypothetical browser alert, choose a product page with a real compatibility question and document what happens after the customer returns. Can the shopper find the answer on the page, start a suitable help conversation or leave again with the same uncertainty? Compare that route with an eligible WhatsApp message and the colleague’s response, without treating browser subscription as phone-channel permission. WhatFlow can provide a continuing Shopify conversation when the buyer needs help; a browser alert may be sufficient when the page already resolves the decision. Record destinations, questions and orders separately so a click is not described as a completed purchase or a verified improvement in retention.
Pilot one back-in-stock notification with a matched product and timing. Record clicks separately from questions and completed orders. Ask staff whether the conversational replies revealed problems a one-way alert would have missed.
WhatFlow’s allowance and team costs
For a concrete baseline, consider 5,000 sent messages in a month. Among the listed WhatFlow plans, Plus produces an app-side cost of $9.99 at that volume. This calculation uses its $9.99 base, 5,000 included sends and $0.004 rate above the allowance. It assumes a single monthly allowance and does not include tax or Meta delivery charges. It is a planning example, not a combined quote for every possible message category or destination.
Keep three lines in the budget: the application, applicable WhatsApp delivery fees, and any separate implementation or services. Meta pricing varies by destination and category, and some service or qualifying utility messages have different treatment. An app allowance does not override Meta’s rules. The current installation terms and rate pages should be checked before committing a campaign budget.
The features you keep as the store grows
The storefront WhatsApp buttons remain free forever and can fit the Shopify theme and design. The button is an entry point, not a promise of unlimited free automated sends. Automated messaging still follows the selected allowance and applicable delivery rules. Keeping those two costs separate makes the free offering easier to understand.
A sensible first rollout
For implementation detail, continue with Coordinate email, SMS and WhatsApp without overwhelming customers.
Before you choose a platform
- Check whether the destination answers the product question.
- Maintain each channel’s permission record.
- Separate clicks, replies and completed orders.
