Not exactly the way it should be but I believe:

1.  If your email is in the "Email ID" field of the client (see "Business Details / Edit Business Contact Info") then the transmission and acceptance emails will be returned to you (your email address).  Your email will also show up on the Form 1096 but not on the Forms 1099 that accompany it.  [Got to be a known problem.]

2.  Last year, I came to the conclusion that, after filing a number of 1099s prior to the date the IRS' efile opened back up in late January, those filings just sat in limbo at Intuit waiting to be processed.  Hence, the acceptance notification emails were returned to me out of order from the filing notification emails.  That is, the ones I filed after IRS' efile was first opened in late January, were returned faster than the ones I filed in mid-January and got acceptances on in early February.

That's all I got.
