Talk to usIf Amazon Ads suddenly stops spending, establish whether the issue affects one target, one book, a marketplace, or the whole account. Check campaign status, payment messages, budgets, and product eligibility before raising bids. When those checks do not explain a broad interruption, ask Amazon Ads support to investigate an account restriction.
Adigy’s founder has encountered accounts or markets that could not spend despite apparently adequate bids and budgets. This guide turns that support workflow into a diagnostic process. “Spend block” describes the symptom; it is not proof of a specific Amazon limit or its cause. Platform references were reviewed September 26, 2026.
1. Identify the scope of the problem
Use Campaign Manager reporting to compare the affected period with an ordinary earlier period. Confirm the account, marketplace, currency, date range, and reporting time zone. A partial day is a poor comparison with a full day, and the most recent figures may still be updating.
Write down what changed: impressions, clicks, and spend. No spend can mean there were no clicks despite continuing impressions. That calls for a different investigation from a sudden disappearance of impressions across otherwise active campaigns.
- One target: inspect its status, relevance, exclusions, bid, and available demand.
- One book across campaigns: inspect that ASIN’s availability and advertising eligibility.
- Several books in one market: inspect market-specific billing, account messages, and shared limits.
- Many markets at once: look for shared account or payment issues and recent account-wide changes.
Do not repeatedly search Amazon to decide whether your ads are running. Amazon notes that live ad visibility is not guaranteed for your own searches; use reporting and the ad-status diagnostics.
2. Check the visible causes first
Open the relevant campaigns and read both campaign-level and ad-level messages. An active campaign can contain an ad with a separate eligibility problem.
| Observation | Check | Response |
|---|---|---|
| Out of budget | Campaign budget, any portfolio cap, and applicable advertising settings. | Change a limit only if the extra spend fits your plan. |
| Paused, scheduled, or ended | Enabled state, dates, and recent changes. | Correct an unintended setting; preserve deliberate pauses. |
| Pending or rejected | Review status and the specific reason supplied. | Follow the review or correction process. |
| Payment failure | Billing notifications and the payment profile. | Resolve the payment issue before trying to increase delivery. |
| A book is ineligible | Selected format, availability, listing status, and Featured Offer. | Investigate the product-level problem. |
| Eligible but low exposure | Targeting, exclusions, competition, demand, and affordable bids. | Review the campaign economics before making adjustments. |
The status checks follow Amazon’s campaign troubleshooting guidance. “Delivering” indicates eligibility to serve; it does not promise that your desired budget will be spent.
For author Sponsored Products, Amazon’s book eligibility rules say Amazon itself must hold the Featured Offer. A third-party seller winning that offer can therefore explain why a book’s ads stop. Follow the KDP Buy Box troubleshooting guide when the interruption is specific to a book.
3. Separate budgets, billing, and restrictions
A campaign budget is an advertising control. A billing threshold or credit limit is part of collecting payment. An account restriction may require Amazon’s investigation. Similar-looking spend patterns do not establish that these are the same problem.
Amazon’s billing-cycle guidance explains that sponsored-ad invoices can be triggered by reaching a credit limit. An invoice threshold should not be assumed to be a permanent daily campaign cap. Ask support which limit applies to your account rather than inferring it from the size of one charge.
If the payment method cannot be charged, Amazon says campaigns can pause. Its payment-failure instructions cover checking payment details, available funds, and issuer restrictions. Use the secure billing interface; do not paste card details into a support message.
Repeated bid increases will not resolve an unpaid invoice or an ineligible book. They can also leave you with unexpectedly expensive settings when delivery resumes. Keep a record of any temporary changes.
4. Prepare a support case with evidence
Use Help or Support Center in the Amazon Ads console, select the affected account, and choose Contact Us. The available contact method can vary. Keep the case ID and follow the case in the support log so the investigation has one clear history.
Provide the account/profile identifier, marketplace, relevant campaign IDs and ASINs, dates and time zone, observed spend, screenshots of status messages, and the checks already completed. Include a comparison period without claiming that historical spend is guaranteed future demand.
Subject: Please investigate unexpected advertising delivery restriction — [marketplace/profile]
Hello Amazon Ads Support,
Since [date and time zone], [affected campaigns/books/marketplace] have shown [specific change in impressions and spend]. During [comparison period], the same scope recorded [figures and currency].
I have checked [campaign/ad status, budgets and portfolio caps, payment status, dates, and book eligibility]. The current messages are [exact status text]. Relevant campaign IDs and ASINs are [identifiers]. I have attached screenshots and a report for the affected dates.
Could you confirm whether there is a billing, verification, credit, or account restriction affecting delivery, identify the required action, and advise when we should follow up? If no restriction applies, please help identify the cause of the interruption.
Thank you, [name].
Replace each placeholder with facts from your account. If support requests a document, submit it through the designated secure channel. Follow up in the existing case after the stated response window, adding any new evidence. A historical case resolved quickly does not establish a deadline for another account.
A worked diagnostic example
Fictional example: an author notices that four books in one marketplace have each lost most of their impressions over several complete days. Campaigns appear active, but increasing two bids has not restored delivery.
The author records the affected dates, checks the ad-level messages and shared portfolio settings, then inspects billing for that marketplace. If a payment failure is visible, resolving it is the next step. If the checks are clear, the author sends the evidence to support and asks whether a restriction exists. The low spend alone is insufficient to diagnose a hidden cap.
If only one of those books had stopped, a change in its Featured Offer or availability would deserve attention before an account-wide theory. This distinction saves time and avoids changing healthy campaigns unnecessarily.
5. Check recovery before scaling
After a correction or support response, confirm that impressions and clicks resume in the affected scope. Recheck any temporary bid or budget increases and keep spending within your intended limits. Record the resolution and case number for future reference.
Restored delivery is only the first step. If traffic returns but sales do not, use the clicks-without-sales diagnostic and review royalty-based advertising economics.
Adigy automates recurring campaign decisions within your selected goals. Amazon still controls billing, account restrictions, and ad eligibility. Automation cannot override those platform decisions; a support case is appropriate when the cause requires Amazon’s intervention.
