Buyer-Seller Messaging vs Request a Review: What You Can Send

Quick answer: Request a Review is a standardized, one-per-order message Amazon controls end to end. Buyer-Seller Messaging is a narrow support channel for genuine order issues. Using messaging to run a custom review campaign — proactive "checking in" emails, positive-review pitches, incentive offers — is outside policy, and buyers can opt out of non-essential messages anyway.

There used to be a thriving industry of custom Amazon follow-up email sequences. Amazon has steadily narrowed what that channel is allowed to do, and a lot of old advice is now a liability. Here's the current split.

Two channels, two purposes

Request a Review is Amazon's official solicitation. One standardized message per order, Amazon's wording, sent 5–30 days after delivery, asking for a product review and seller feedback together. You can't edit it, add anything to it, or send it twice. Its entire design is to be neutral. Review request vs feedback request covers what it actually contains.

Buyer-Seller Messaging is a support channel. Its permitted uses are things like resolving a shipping problem, answering a product question, arranging a return or replacement, or clarifying an order detail — communications necessary to complete the order or respond to a customer service issue. It is not a marketing channel.

What you can send in a buyer-seller message

Broadly, messages that a reasonable person would consider necessary for the transaction:

• Responding to a buyer's question or complaint.
• Notifying about a delay, a substitution, or a stock issue on their specific order.
• Coordinating a return, refund, or warranty claim.
• Requesting information needed to fulfill (e.g. a customization detail, a clarification on a shipping address).

These should be plain, order-specific, and free of marketing. No logos-heavy templates, no links to your other products, no newsletter signup, no "while I have you" upsell.

What you can't send

• Proactive review or feedback solicitations with custom wording. The compliant way to ask is the official call.
• Order confirmation / shipping confirmation messages. Amazon already sends these; duplicating them is prohibited.
• "Just checking everything arrived OK" messages sent with no actual issue — these are thinly disguised review setups and Amazon treats them as unsolicited.
• Anything offering compensation tied to a review, a rating, or the removal of a negative one.
• Messages to buyers about an existing negative review or feedback, beyond a single permitted attempt to resolve a genuine order problem.
• External links, marketing images, or attachments not required to resolve the issue.

Buyers can also switch off non-critical messages entirely in their communication preferences, and Amazon may not deliver messages it classifies as marketing. So even a borderline-permissible message may simply never arrive.

Why the old "drip sequence" playbook is dead

Five years ago, a three-email post-purchase sequence — thanks, tips, review ask — was standard. Today each of those emails is a potential problem: the "thanks" and "tips" messages have no order-necessary purpose, and the review ask should be the official call instead. Sellers still running legacy sequences through third-party tools are often accumulating policy risk they've forgotten about.

One seller carried over a four-email flow from an old tool when they switched platforms. It ran quietly for months until a batch of buyers reported the messages as unwanted. The account got a communication-policy warning. The fix was to delete the whole sequence and rely on the official Request a Review — which, it turned out, was producing a similar review rate without the risk. Review request automation and what's allowed has the fuller compliance picture.

The clean setup

• Review solicitation: the official Request a Review call, once per eligible order, automated so nothing is missed. Nothing custom.
• Buyer-Seller Messaging: reactive only, or proactive only when there's a real, specific order issue. Plain text, order-scoped, no marketing.
• Delete legacy email sequences entirely, rather than trimming them — a "safe" version of a marketing drip usually isn't.
• Keep a record of what solicitation went out per order, so you can prove the process is the official one.

The counterintuitive part: giving up custom messaging usually costs you very little in reviews, because the official call plus full coverage does most of the work — and it removes an entire category of account risk.

EcomSanity's review automation uses only Amazon's official Request a Review call, with a visible per-order history — there's no custom-message option to misuse, by design. For a comparison against tools that still lean on buyer messaging, see best Amazon review request software.
