I am using Gravity Forms 1.6.12 running on WordPress 3.4.2. Also using the Authorize.net add-on 1.3 to tie into my clients credit card processing company.
I currently use two type of email notifications. An internal or Admin one to notify the client (multiple people get it) so they can schedule shipment of the product.
Then another to the User and/or customer that details their order and asks them to verify all the information they provided was correct.
This is where things get strange and I could use some help.
We process around 20-25 orders a day from multiple forms. 100% of the time the transaction shows up in Authorize.net. About 5-7% of the time we don't get our Admin notification (not sure about our clients). There are multiple people on the distribution list and none of us get it.
Of course we know we are not getting the Admin emails cause well, we can compare it to the emails we get from Authorize.net when the transaction has been completed.
When I go into WordPress/Gravity Forms I see the entry in question, and when I go to the Entry page and "Resend Notifications" it then works 100% of the time with no delay.
I've tried everything. It is not form specific. Time of day. Fields completed or not completed. So I am asking for help.
BTW: I would provide a URL, but the pages where the forms are located are password protected and used by an internal sales force. They include info my client would not want me to make public.
P.S. I just saw a similar topic, and will do some work at this URL the admin directed other people to, but figured I'd ask the above anyway.
