我是领了 Google Cloud 的 300 美元使用金，今早收到这样的邮件↓

Hi xxx,

My name is Sarah and I ’ d like to personally connect with you about maximizing your trial and to understand any customer feedback you might have to share.
 
I can also help connect you and your team with support or our developer communities if needed.
 
If you're open to it, let me know a quick time to chat later this week or next, or you can book some time on my calendar directly here.

Thanks,

Sarah Barbour | Cloud Sales & Customer Growth | [email protected] | 404-400-8203

各位能帮我解释一下吗？
免费增值？要写反馈？
