Because we send our emails to a large number of retirees, Gmail frequently puts our emails into the Promotion tab. You should carefully look through your promotion emails and if you see the IRO email, here is how to force the IRO emails into your Primary tab.
1. In your Promotions Tab, left click and HOLD on the email and move the email to the Primary tab.
2. You will see in a yellow pop-up box the following:
The conversation has been moved to “Primary”. Undo
Do this for future messages from intelretiree@gmail.com? Yes
3. Click Yes and from now on you will receive your IRO emails in your Primary Inbox.
