Google uses a tabbed system to sort your incoming email. When you log into your Gmail account, you will see at least three tabs along the top of your inbox:
As a result, emails from us might be placed under the “Promotions” tab along with other such designated emails. This may cause you to miss our emails and lead you to believe you have not received them.
Be sure to check “Promotions” for emails from us. If you find one of our emails under your “Promotions” tab, drag it to the “Primary” tab. When you do this, the following message should appear at the top of the page:
The conversation has been moved to “Primary.” Undo
Do this for future messages from <email address>? Yes (click Yes)
Clicking “Yes” will ensure that all future messages from that address are sorted to the “Primary” tab, where you’ll be more likely to notice.
