Amazon reads every message you send a customer, and 'we're a family business' can get it blocked

Key takeaways

• Amazon divides seller-to-buyer communication into necessary permitted messages — those required to complete an order or answer a question — and proactive permitted messages, which are narrowly defined.
• AI scanning every buyer-seller message and blocking persuasive language, external links, emojis and incentives, with even 'we're a family business' or 'please leave 5 stars' triggering blocks.
• Format rules: no phone numbers or email addresses unless required to complete the order, no attachments unless necessary for fulfillment, no logos or branded images.
• Constraints: a 30-day window, the order ID included, and the message written in the buyer's language.
• One detail agencies flag repeatedly: personalized greetings using the buyer's name get blocked in practice. Amazon's guidelines do not spell this out, so treat neutral greetings plus product-specific detail as the safe default.

Write “we’re a small family business” in a buyer message and Amazon’s filter may block it. Post-purchase messaging is the last place sellers try to build a relationship with an Amazon customer, and Amazon’s position is that the relationship is theirs. The Communication Guidelines say so in plain terms.

01The two categories

Necessary permitted messages — communications required to complete an order or respond to a customer service inquiry. Answering a buyer’s question about product details, resolving a delivery problem, arranging a return.

Proactive permitted messages — everything you initiate. Narrowly defined, and Amazon already handles much of the post-purchase communication sellers used to send themselves.

The practical consequence: if the buyer did not ask and the order does not require it, the message probably does not need to exist.

02What gets blocked

Blocked content:

Blocked	Note
Persuasive or marketing language	Including sentiment such as “we’re a family business”
Review requests with sentiment	“Please leave 5 stars”
External links	Any off-Amazon URL
Emojis	Blocked
Incentives	Discounts, free products, compensation of any kind
Phone numbers and email addresses	Unless required to complete the order, described as rare
Attachments	Unless necessary for fulfillment
Logos and branded images	Prohibited
Buyer-name personalization	Blocked in practice, per agency reports

The name rule surprises people, because personalization is standard practice everywhere else. Agencies give the example directly: “Hi Sarah! Your 12-pack water bottles are on the way!” is blocked; a neutral greeting paired with product-specific detail — “Hello! Your [product] is on the way” — is the compliant alternative.

03The format rules

Amazon’s requirements for a compliant proactive message:

• Within 30 days of the order
• Order ID included
• Written in the buyer’s language
• No prohibited elements from the list above

04What happens when you get it wrong

Consequences escalate:

Blocked messages — the immediate outcome, and the useful one, because nothing reaches the customer.

Restriction to pre-approved templates — Amazon limits you to its own message formats.

Account warnings, and suspension on repeated violations.

And the diagnostic problem covered in the review manipulation guide: notices do not specify which message triggered them, so a template running across thousands of orders produces a flag you then have to locate yourself.

05The rule that resolves most of it

Reporting’s own conclusion, and it is the right one:

Use Request a Review for feedback. Reserve custom messages for genuine order issues. If you are unsure whether a message complies, do not send it.

Request a Review sends Amazon’s own standardized message between 5 and 30 days after delivery, with content Amazon controls and the seller cannot customize. That lack of control is the feature — there is nothing in it for an algorithm to flag.

Which makes the calculation straightforward. A custom message might convert marginally better. A blocked-message pattern costs account health, and a review-manipulation flag costs considerably more.

06Where automation fits

tools that automate messaging with templates designed to follow current rules, and recommends reviewing automated campaigns periodically against policy updates.

Two cautions:

A tool does not transfer responsibility. A template that was compliant when written and is not now is your violation.

Volume amplifies error. A slightly non-compliant message sent once is a blocked message; the same message on automation across a catalog is a pattern — which is what the flagging systems look for.

07What to do

Audit any active message template against the blocked list, particularly for buyer names, emojis and persuasive phrasing.

Remove review-request language entirely and use Request a Review instead — the same conclusion as the inserts guide.

Keep proactive messages to genuine necessity. If the buyer did not ask and the order does not require it, do not send it.

Include the order ID and stay inside 30 days on anything you do send.

Review automated campaigns quarterly against current policy rather than treating a template as permanent.

When in doubt, do not send. Reporting’s own advice, and the cost of following it is one message that would probably have been blocked anyway.

Pull up the last proactive message your account sent. If the buyer did not ask for it and the order did not need it, delete the template — and use Request a Review instead.

Frequently asked

What can I message a buyer about?

Necessary permitted messages — those required to complete the order or respond to a customer service inquiry. Proactive messages are narrowly defined, and Amazon already handles much of the post-purchase communication sellers used to send.

Can I use the customer's name?

Amazon's Communication Guidelines do not ban the name outright, but agencies report personalized greetings being blocked by the filter. Neutral greetings paired with product-specific detail are the safe default.

What gets a message blocked?

Persuasive or marketing language, review requests with sentiment, external links, emojis, incentives, phone numbers and email addresses, attachments, and logos or branded images. AI scanning every message.

What are the format rules?

Within 30 days of the order, order ID included, written in the buyer's language, and free of prohibited elements.

What happens if I break the rules?

Blocked messages first, then restriction to pre-approved templates, then account warnings and suspension on repeated violations — with notices that do not specify which message triggered them.

Should I use messaging or Request a Review for feedback?

Request a Review. It sends Amazon's own standardized message that you cannot customize, which is precisely why there is nothing in it to flag.
