Amtrak Guest Rewards - receiving referral from agr

Hi all.
I joined the AGR program the other day, booked my travel for june (w/in the 90 days). Im traveling with my kids and Im trying to set them up w/ a referral so we can get the bonuses.

So I go to the agr site, click on promotions, enter their emails, site says it will contact them with invitation to join and then they never get any email invitations. I checked the spam folder. I tried another email address of mine, just to see, and nothing there either (different email, one is gmail one is comcast.

Is there any reason that *I* cant refer yet? I mean, I understand none of the bonuses happend until we complete travel in 90 days, but why wouldnt my referalls get their invitations?

thoughts?

Thanks!

Nan

Please PM me one of their email addresses I want to check something. I WILL NOT send them an invitation.
I received a PM from the OP and put the email address he gave me into the AGR refer a friend box. It appears AGR will accept the email address as I got the little smiley face not the frowny face. I have no idea why the referral is not sent/received to the email address.

Can anyone thin of a reason?

I tried sending a referral yesterday afternoon. As of this morning, the recipient has not received anything.

Update: Referral went through on the 2nd try.

Just sent a referral to an alias on a hotmail account that I don't use. We'll see what happens. The referral invite came within a few minutes.
