A surprising Keesler outcome for me this morning. But this might not surprise you if you’re an old Keesler hand:
I went to the Keesler website a couple days ago and linked up my external Ally account. They sent the trial deposits to Ally which I verified this morning, activating the link.
I then sought to use the Keesler transfer function, at their website, to pull funds out of Ally via ACH for deposit into my Keesler account. Keesler at that point told me those funds would be credited to my Keesler account today! Never having performed this maneuver prior at Keesler, I was quite surprised. Now here is the downside:
First, regardless what it says, I have no inkling whether or not Keesler will actually deliver same day ACH service.
Second I don’t know, even if the funds materialize today, whether or not they will be available and if not when they will become available.
Finally third, and this is the bigee:
Keesler is not allowing me to transfer funds, coming from Ally, directly into my HIMMA Plus account. My only transfer option is into savings. Presumably I would have to telephone Keesler to request movement of those funds into HIMMA Plus, which is a nuisance. The funds would certainly be “new money” . . . but still a nuisance.
I am currently waiting for Keesler to open so I can telephone them and, with luck, obtain answers to several questions raised by the above.
ETA
Just off the telephone with Keesler. Am gonna try this. The Keesler rep confirmed impossibility of pulling funds directly into my HIMMA Plus, from Ally, when the ACH is initiated at Keesler. 
However, she said that if I call in once the money is in savings that it can be moved straightaway into HIMMA Plus by a rep. She said there is no hold.
We shall see.
