Amazon Seller Messaging: How the Buyer-Seller Messaging Center Works and How to Stay Inside the Rules

Amazon seller messaging is the Buyer-Seller Messaging service inside Seller Central, the channel Amazon expects you to use for order questions, pre-sales questions and a small set of permitted proactive messages. Two rules govern it: reply within 24 hours, and stay inside Amazon's messaging policy, no marketing, no external links, no review requests outside Request a Review. This guide covers both, plus templates, opt-out handling, automation and how to run the inbox from a helpdesk.

Where the Buyer-Seller Messaging center is and how it works

Buyer-Seller Messaging lives inside Seller Central, under Messages in the left-hand menu, and inside the Amazon Seller app under the same name. Every message that arrives there is tied to an order: a shopper's question about a shipment, a request before they buy, or an automatic notice such as an A-to-z Guarantee claim.

Each message carries its own response clock, separate from the order itself. Amazon shows the time remaining next to the thread, and a store's average response time rolls up into account health.

Two settings are worth switching on before anything else. In Seller Central go to Settings, then Notification Preferences, and enable Buyer Messages so new messages are pushed to you rather than waiting to be found. In the Amazon Seller app, turn on push notifications for Buyer Messages only, so order and ranking alerts do not bury them.

Sellers sometimes confuse this with the shopper's own inbox, where a buyer sees Amazon's order updates and any note flagged [Important]. The two are separate systems. A seller only sees what buyers sent to them; a shopper only sees what the seller sent through Buyer-Seller Messaging plus Amazon's own system messages. If you are checking a message you received as a customer rather than a seller, this guide is not the one you need; that is Amazon's order tracking and notifications, not Seller Central.

The 24-hour response rule

Amazon expects a response to every buyer message within 24 hours, including weekends and holidays.

A response is any reply, not necessarily a resolution: acknowledging the message and giving a timeline counts. Marking a message "no response needed", available for messages that do not require action, stops the clock without counting as unanswered.

Late responses show up in account health under a response-time metric. Amazon does not publish a single hard cutoff for suspension risk tied to this metric alone, but a pattern of late replies compounds with other account health signals, and a poor response-time rating is one of the triggers for Amazon capping your message quota. Our guide to the Amazon 24-hour response rule covers how to stay inside it at volume.

Most sellers set an internal target well under the ceiling, because the clock does not pause for time zones or team availability: under 6 hours during business hours and under 12 hours outside them is a workable standard, and it leaves room for the day when volume spikes.

A-to-z Guarantee claims run on their own resolution clock, separate from ordinary buyer messages. See our guide to Amazon A-to-z claims for how that timeline works.

What you can and cannot send: the messaging policy

Buyer-Seller Messaging is for order-related communication: order status, product questions before or after a purchase, and the small set of proactive messages Amazon allows, such as a critical delivery update or a customization question.

What is not allowed: marketing or promotional language, links to any site outside Amazon, requests for positive reviews or feedback (a general "we appreciate feedback" line is fine, asking for five stars is not), emojis or non-text formatting, and repeated messages to a buyer who has not replied. Attachments are allowed only in the file types Amazon permits (PDF, JPEG, PNG) and only where the order needs them, such as an instruction sheet.

Buyers can flag a message as inappropriate, which puts it in front of Amazon directly. A message that reads like a form letter with a hidden ask, add a coupon code, follow us on Instagram, tends to get flagged even when it is not overtly promotional. Audit a sample of 50 sent messages every quarter; if any would fail the table above, fix the template and retrain the team.

Buyer opt-out and what it changes

Buyers can opt out of unsolicited seller messages in their Amazon account settings. Once opted out, they still receive messages critical to the order, delivery scheduling, a customization question, or a shipping address problem, but nothing else gets through.

If you message an opted-out buyer with a non-critical note, Amazon blocks it and sends you a bounceback rather than penalising the account.

To reach an opted-out buyer with something critical, put the word "Important" in brackets anywhere in the subject line before sending, from the buyer's page in Manage Orders. Keep the message limited to what is actually needed to complete the order; buyers can flag these as inappropriate too if they read as anything else.

An opted-out buyer is not blocked from replying to you. If they message you first, or reply on an existing thread, your response goes through normally; the opt-out only blocks messages you start.

How to message a buyer, and how buyers reach you

To message a buyer first: open the order in Manage Orders, select the buyer's name or "Contact Buyer", and choose a message category before writing. Amazon requires the category so it can route and check the message against policy before it sends.

Buyers reach a seller through the order page or their purchase history, and separately through an A-to-z Guarantee claim, which lands in the same inbox but follows a different resolution path.

If a buyer emails a seller's account outside Buyer-Seller Messaging entirely, rare, and against Amazon's own guidance for buyers, reply from the same thread if one exists. Keeping everything inside the system Amazon can audit protects the seller if a dispute comes up later.

Templates that pass policy

Seven templates you can paste and adjust. Each is order-specific, carries no links outside Amazon and no marketing language.

Order question answered

Order [Order ID]: your [product] shipped on [date] via [carrier]. Track it here: [tracking link]. Expected delivery: [date]. Let me know if anything looks off.

Why it stays inside policy: order-specific, no marketing language, no review request.

Shipping delay

Order [Order ID] is running behind schedule. Updated delivery estimate: [date]. I'll flag it if anything changes before then.

Why it stays inside policy: factual update only, nothing that reads as a review ask.

Return request

Sorry the [product] didn't work out. To start a return, go to Your Orders and select Return or Replace; a prepaid label is generated automatically. Once the item arrives back, the refund is processed within 2 to 3 business days.

Why it stays inside policy: directs the buyer to Amazon's own returns flow, no external link, no incentive.

Replacement offered

Sorry your [product] arrived damaged. I can send a replacement or issue a refund, whichever you'd prefer. Hold onto the damaged item until I confirm which.

Why it stays inside policy: order-specific resolution, no links, no incentive attached.

Critical message under opt-out

Subject: [Important] Delivery address confirmation needed

Your order [Order ID] can't ship until we confirm the delivery address on file. Reply with a confirmation or an update and I'll get it moving.

Why it stays inside policy: matches Amazon's own definition of critical, subject carries [Important] as required for opted-out buyers.

Pre-sales answer

Yes, [product] comes in [detail]. Happy to answer anything else before you order.

Why it stays inside policy: answers a genuine pre-sales question, no proactive marketing beyond what was asked.

Positive feedback acknowledgement

Thank you for taking the time to share that. I'm glad the [product] is working well for you. If anything else comes up, I'm a message away.

Why it stays inside policy: thanks the buyer without asking for a rating, a review or anything else.

Our Amazon email templates post has more templates across every stage of the order.

Handling volume: rules, routing and auto-replies

Above roughly 100 messages a day, staying inside 24 hours on Buyer-Seller Messaging alone gets hard without some structure. Three things help before adding any tool.

Route by order status, so shipping questions and damage claims do not sit in the same queue as pre-sales. Tags such as Returns, Shipping Delay, Product Inquiry and Peak Season Surge, with one colour per tag, make the queue readable at a glance.

Use an acknowledgement that tells the buyer you have seen the message without answering it. This does not stop the response clock, but it buys goodwill while a full answer is prepared.

Keep a short set of approved templates so common questions are not rewritten from scratch each time, and set aside one block of time a day to clear similar messages together rather than switching between them.

Seller Central has a built-in option under Settings, then Messaging Automation, but it is limited. Two rules cover most of what it can usefully do:

The harder problem is that Amazon messages do not sit next to messages from other channels. A seller running Amazon alongside eBay, a Shopify store or a webstore chatbot ends up checking several inboxes to keep every channel inside its own response clock.

When to escalate to Amazon

Some problems only Amazon can fix: a fraudulent A-to-z claim, an account suspension, a message quota cap that will not lift. Open a case in Seller Central under Help, then Get Support, with a one-paragraph summary and the order or case ID ready; a clear case gets a faster answer than a long one. Record the case ID in the buyer's thread so whoever picks it up next knows it is with Amazon.

For a policy question that seems unclear, the Amazon Seller Forums are worth a search first. Experienced sellers post the wording and the workarounds that got a case resolved, and the same question has usually been asked before.

Answering Amazon messages from a helpdesk

Running Buyer-Seller Messaging inside a helpdesk changes a few things. Each message keeps its order attached and its own SLA timer, so a team can see which messages are close to breaching 24 hours without opening Seller Central. Templates carry a policy check built in, so a reply that would trip Amazon's filters gets flagged before it sends rather than after a buyer reports it. Each reply is recorded against the agent who sent it, which Seller Central does not do, so you can see who answered what and coach from it.

AI-drafted replies work from the same policy rules: an AI Agent can draft or send routine answers, shipping status, order questions, within the constraints above, while anything needing judgement goes to a person. Amazon sits beside eBay, Shopify and a webstore chatbot in the same inbox, so a team working multiple channels is not switching tools to stay inside each one's response clock.

eDesk connects to Buyer-Seller Messaging directly through Seller Central authorisation, without a separate bridge or email forward. Our Amazon helpdesk software page has the full setup across marketplaces.

Frequently asked questions

Where do I find buyer messages in Seller Central?

Under Messages in the left-hand navigation, or inside the Amazon Seller app under the same name. Each message is tied to the order it came from, and shows the time left to respond.

How fast do I have to reply to Amazon messages?

Within 24 hours, including weekends and holidays. Marking a message "no response needed" stops the clock for messages that do not require an answer.

Can I send promotional messages to Amazon buyers?

No. Buyer-Seller Messaging is for order-related communication only. Marketing language, external links and review requests outside Request a Review all breach policy.

What happens if a buyer has opted out of messages?

They still receive messages critical to the order, delivery scheduling, customization questions, shipping address issues, sent with [Important] in the subject line. Everything else gets blocked and bounced back to you.

Can I add attachments to a buyer message?

Yes, in the file types Amazon permits (PDF, JPEG, PNG) and only where the order needs them, such as an instruction sheet. Decorative images and anything promotional are not allowed.

Why has Amazon capped my message quota?

Amazon limits messaging when a seller breaches policy or has a poor response-time rating. Fix the templates that caused it and bring replies inside 24 hours; the cap normally lifts after about a week.

Can I answer Amazon messages from a helpdesk?

Yes. A helpdesk like eDesk keeps the order and SLA timer attached to each message, applies a policy check to replies, records which agent replied, and sits Amazon beside other sales channels in one inbox.
