根据计费常见问题的

为什么我的邮箱配额在启用帐单后不会增加？

Google将等到第一笔付款被清除后才能增加邮件配额。这意味着需要至少7天才能获得更高的配额。

Dear AppEngine people (I understand that all AppEngine support has moved to *** - if I am mistaken then sorry for posting this here), I have a very serious problem that I hope you can help me to resolve.

Yesterday I enabled billing with a daily budget of $500 on my application (friendbazaar.appspot.com), and my billing status is "Enabled". However, I am still showing that I have maxed out my usage of recipients emailed at 100 of 100.

The quota was just reset 2 hours ago, and so I don't understand why this has not reflected the updated quotas based on the billing settings.

This is a big problem, since I recently sent out invitations to members of my other sites (over 100K people) to sign up for this new site - and since email authorization is required to complete the registration process, I am totally hosed and have basically pissed off a lot of customers by making them register and then never sending them the email to complete the process.

Please let me know if this can be fixed, and what the normal delay is for appengine quotas to reflect billing settings.

Per the billing FAQ's

Why did my mail quota not increase after I enabled billing?

Google will wait until the first payment is cleared before increasing your mail quota. This means it will take at least seven days to get the higher quota.
