请教，亚马逊把广告活动建议发到我们的A邮箱来了，但问题是我们的A邮箱不是此亚马逊账号的注册邮箱，照理说亚马逊是不会知道这个A邮箱的。这是怎么回事？
以下是邮件内容，我看了下发件人是亚马逊某广告客户经理的的邮箱。
 
Hope you are doing well.

We would like to offer you a recommendation to help improve your Sponsored Products campaign(s) in  after having reviewed your campaigns’ performance.

You can further optimize your Sponsored Products campaign(s) by enabling a new bidding control called rule-based bidding. This new control helps increase conversions while maintaining a ROAS greater than or equal to the ROAS guardrail for your campaigns. Once enabled, Amazon will adjust your bids on each ad opportunity to drive more conversions. This feature is only available through your account manager, so please reach out to Shamyukthaa for any edits.

How this can help your business: This rule will help drive more conversions while trying to meet your ROAS goal. Rule-based bidding allows you to continuously adopt bid suggestions at an impression level within a performance guardrail. We don’t guarantee to meet your ROAS guardrail. If we’re not meeting the guardrail and your ROAS decreases over a 21-day period (excluding special days like Prime Day) we will disable the rule on your behalf.

Please let us know if you are interested by replying to this email with a ‘Yes’ and we will follow up with the details of the recommendation and the link to your advertising account.

Feel free to write back with any questions.
