Key takeaways<\/h2>\n\n\n\n\n- The 24-hour window governs everything.<\/strong> It opens when the customer messages you and resets with every message they send. Outside it you may only send an approved template.<\/li>\n\n\n
- Meta charges per delivered message, business to user only. Messages your customers send you are never charged.<\/li>\n\n\n
- Every business phone number gets 1,000 free service messages a month, which do not roll over.<\/li>\n\n\n
- An abandoned-cart message sent hours later is outside the window by definition, so it is a template, not a free-form DM.<\/li>\n\n\n
- Connecting Shopify, WooCommerce or Etsy puts live products in the message itself rather than a link to them.<\/li>\n\n\n
- A webhook turns an order number into a delivery date mid-conversation – that is the flow with the clearest payback.<\/li>\n\n\n
- Nothing official lets you message someone who has not contacted you first.<\/li>\n\n<\/ul>\n\n<\/div>\n\n\n\n
The Rules Before the Tactics<\/h2>\n\n\n\n
Worth reading first, because two of the most-recommended e-commerce flows are not allowed the way they are usually described.<\/p>\n\n\n\n
The 24-Hour Customer Service Window<\/h3>\n\n\n\n
When a customer messages your business, a 24-hour window opens. Inside it you can reply freely – text, images, product cards, whatever the channel supports. The window resets every time they write again.<\/p>\n\n\n\n
Outside it, free-form messages are not permitted. You may only send a pre-approved template. This single rule is why ‘just set up an abandoned cart DM’ is bad advice when it is stated that simply.<\/p>\n\n\n\n
It is their clock, not yours<\/h4>\n\n\n\n
Nothing you send extends the window. Only a message from the customer does, which is a good argument for flows that ask a question.<\/p>\n\n\n\n
Templates are a separate system<\/h4>\n\n\n\n
Marketing, utility and authentication templates can be sent any time, but each is submitted for approval and priced differently.<\/p>\n\n\n\n
What Meta Actually Charges<\/h3>\n\n\n\n
Meta publishes its rates<\/a>, and they changed shape in July 2025: billing is per message rather than per conversation, by category and by the customer’s country, charged only when a message is delivered and only from you to them. Messages customers send you cost nothing.<\/p>\n\n\n\nThe number that matters for a small store: every business phone number gets 1,000 free service messages a month. They do not roll over, they reset monthly, and charging starts at the 1,001st. For a shop answering a few dozen people a day that is the whole month.<\/p>\n\n\n\n
Ads buy you a discount<\/h4>\n\n\n\n
A customer arriving through a click-to-WhatsApp ad opens a free entry point window of up to seven days, where marketing, utility, authentication and service messages are not charged.<\/p>\n\n\n\n
Meta’s own AI agent is priced apart<\/h4>\n\n\n\n
Meta Business Agent became a fifth billing category in July 2026 at $2 per million tokens – roughly four to five cents a message – with no free tier and no volume discount, and it is charged even inside that free window.<\/p>\n\n\n\n
Nobody Can Message First<\/h3>\n\n\n\n
No official connection on any channel lets you start a conversation with someone who has not written to you, outside an approved template with opt-in. Tools advertising unsolicited DMs at volume are using unofficial clients, and the account that gets banned is yours.<\/p>\n\n\n\n
Outbound is a genuinely different product with a different method. For Instagram that is the DMpro Chrome extension<\/a>, which sends from your own account at human pace; for business-to-business it is contactID<\/a>, which uses contact forms.<\/p>\n\n\n\n![\"Ecommerce](\"https:\/\/dmpro.brandid.app\/blog\/wp-content\/uploads\/2026\/10\/ecommerce-dm-automation-window.jpg\")
Same message, allowed or blocked, depending only on what happened last.<\/figcaption><\/figure>\n\n\n\nThe Flows Worth Building<\/h2>\n\n\n\n
In rough order of payback. The first two cover most of the volume in most stores.<\/p>\n\n\n\n
Order Status<\/h3>\n\n\n\n
The highest-volume question in e-commerce and the most satisfying to automate, because the answer exists in a system you already have. The customer sends an order number, a webhook looks it up mid-conversation, and the reply carries a real delivery date instead of a promise to check.<\/p>\n\n\n\n
Done properly this removes a whole category of message from the human queue rather than just delaying it. Order status automation<\/a> covers the build.<\/p>\n\n\n\nProduct Questions and Recommendations<\/h3>\n\n\n\n
Connecting your store puts live products inside the message. DMpro connects Shopify, WooCommerce, Etsy, BigCommerce, Magento, Squarespace, Wix, Gumroad, Printful and Spring, and once connected the products appear in the campaign builder as a catalogue you pick from.<\/p>\n\n\n\n
That is the difference between sending someone a link and sending them the product. On Instagram, Messenger and WhatsApp the card renders natively in the chat.<\/p>\n\n\n\n
The Cart Flow, Done Legally<\/h3>\n\n\n\n
Here is the honest version. If the customer is messaging you now, you are inside the window and can send whatever helps. If they abandoned a cart two hours ago and have not written, you are outside it, and the only compliant route is an approved utility or marketing template with opt-in on file.<\/p>\n\n\n\n
That is not a reason to skip it – templates work – but it is a reason not to build it as a free-form DM and wonder why it silently fails. Abandoned cart DMs<\/a> goes through it.<\/p>\n\n\n\nReturns and Post-Purchase<\/h3>\n\n\n\n
The messages after the sale decide whether there is another one. A returns flow that gives a straight answer at eleven at night costs nothing inside the free allowance and prevents the review you did not want. See returns automation<\/a> and post-purchase flows<\/a>.<\/p>\n\n\n\nWhat Each Channel Gives a Store<\/h2>\n\n\n\n
Capabilities differ per channel, and the differences change which flow goes where.<\/p>\n\n\n\n
