Email and WhatsApp do not compete; they do different jobs for an online store. WhatsApp is better for short, urgent and conversational messages (delivery updates, order problems, support), but it charges per template message and needs a specific opt-in. Email is better as the record of the order, for visual and long content, and for campaigns to your whole list at a much lower cost per message. For most stores the combination that works is email as the foundation for everything, and WhatsApp for the moments where read speed is worth the extra cost.

In markets like Brazil, India, Mexico or Spain, WhatsApp is part of daily life and customers expect it. In the US it is less common for commerce, and SMS often plays the urgent-message role instead.

## Side by side

| Criterion | Email | WhatsApp Business |
|-----------|-------|-------------------|
| Cost model | Plan or volume based; low cost per message | Per delivered template message, varies by category and country |
| Consent | Opt-in for marketing; transactional needs none | Customer opt-in to business messages |
| Content | Rich: images, multiple products, tables, links | Short: text, media, buttons |
| Record | Stays in the inbox, easy to search | Lives in a chat, mixed with others |
| Read speed | Varies | Usually high |
| Campaign scale | High, low cost | Possible, cost per message |
| Intrusiveness | Low | High if overused |

## How WhatsApp charges

Since July 1, 2025, Meta charges for the WhatsApp Business Platform **per delivered template message**, no longer per conversation ([WhatsApp Business Platform pricing](https://developers.facebook.com/docs/whatsapp/pricing), checked 18 Oct 2026). The key points:

- Templates are categorized as **marketing**, **utility** or **authentication**, and rates depend on the category.
- Rates depend on the recipient's **country calling code**.
- Non-template messages can only be sent inside an open **customer service window**, and they are free.
- **Utility** templates delivered inside an open customer service window are also free.

In practice, a marketing message to someone who has not talked to your store recently always costs money. Across a 50,000-customer campaign that adds up, while the same volume by email fits in low-cost plans. If you use a Business Solution Provider, it usually adds its own fee on top of Meta's rate. The [ecommerce email marketing cost](/blog/ecommerce-email-marketing-cost/) guide compares email pricing models.

## Where email wins

### Order emails

Confirmation, payment receipt, invoice, returns. Customers look for these days or weeks later, and the inbox is the natural place. Transactional email does not depend on marketing consent. See [order confirmation and shipping emails](/blog/order-confirmation-shipping-emails/).

### Campaigns to your whole list

Collection launches, Black Friday, newsletters. Email shows several products with images, prices and links to tens of thousands of people without a high per-message cost. Well segmented, it does not annoy. See [purchase behavior segmentation](/blog/purchase-behavior-segmentation/).

### Long content

Care guides, how-tos, recipes, a welcome series with your brand story. WhatsApp is not the place for long text.

### Customers who did not share a phone

Many customers give an email address but do not want business messages on WhatsApp. Email reaches more of your consented audience.

## Where WhatsApp wins

### Short, urgent messages

"Your order is out for delivery today", "the courier could not find your address". Time-sensitive messages where read speed matters.

### Conversation and support

Pre-purchase questions, exchanges, delivery problems. WhatsApp is a conversation channel, and that is why customers like it.

### A high-value second touch

A high-value abandoned cart can justify a WhatsApp message after the email, for customers who opted in. For small carts, the per-message cost may not pay off. See [abandoned cart emails](/blog/abandoned-cart-email/).

## Consent on both channels

Privacy law applies to both. For marketing email, the standard is recorded opt-in and one-click unsubscribe. On WhatsApp, platform policy requires customer opt-in, and customers can block your number at any time, which affects its quality rating. A phone number collected for an order does not automatically allow marketing. The guide to [email consent for online stores](/blog/ecommerce-email-consent-gdpr/) covers the email side.

## A practical split by moment

| Moment | Email | WhatsApp |
|--------|-------|----------|
| Order confirmed | Always | Optional |
| Payment pending | Yes, with link | Reminder near expiry, with opt-in |
| Order shipped | Yes, with tracking | Yes, short, with opt-in |
| Out for delivery | Optional | Good fit |
| Abandoned cart | First touch | Second touch for high-value carts |
| Welcome | Yes, series | No |
| Campaigns and launches | Yes, segmented | Occasional, for those who asked |
| Review request | Yes | Optional |
| Support | Optional | Yes |

## Common mistakes

- **Sending everything on both channels**: customers get every message twice and start ignoring both, or block your number.
- **Using WhatsApp for generic campaigns**: high cost per message and risk of blocks.
- **Dropping order emails** because "everyone uses WhatsApp": customers still need a record with the invoice and details.
- **Ignoring email deliverability**: if email lands in spam, the store concludes the channel does not work when the problem is setup. See [store campaigns that avoid spam](/blog/ecommerce-campaigns-avoid-spam/).

## Where Pidgely fits

Pidgely is focused on email: API and SMTP for order emails, contacts, segments and broadcasts with one-click unsubscribe, on our own delivery infrastructure. It does not send SMS or WhatsApp. Shopify, WooCommerce, VTEX and Nuvemshop stores can connect natively and send their order emails automatically. See [integrations](/integrations/) and how Pidgely [compares with Mailchimp](/compare/pidgely-vs-mailchimp/).

The short version: start with well-configured email, which reaches your whole list at low cost and keeps the order record. Add WhatsApp for urgent moments and support, always with opt-in.

## Frequently asked questions

### Can WhatsApp replace email for an online store?

No. WhatsApp is great for short, urgent messages and customer conversations, but it charges per template message and requires a specific opt-in. Email remains the channel of record for orders and receipts, long content and low-cost campaigns to large lists.

### How much does WhatsApp Business messaging cost?

Since July 1, 2025, Meta charges per delivered template message, with rates that depend on the category (marketing, utility or authentication) and the recipient's country calling code. Utility templates sent within an open customer service window are free. Check Meta's official pricing page for current rates.

### Do I need consent to message customers on WhatsApp?

Yes. WhatsApp Business policy requires customers to opt in to messages from your business, and privacy laws such as GDPR require a legal basis and transparency. Having a phone number from an order does not automatically allow marketing messages.

### Which channel should handle abandoned carts?

Email first, for everyone with marketing consent, because it is cheap and can show products, prices and a return link. WhatsApp can be a second touch for high-value carts and customers who opted in to that channel.
