We’ve been using this for years as a way for our team to get job requests, the emails show they are being sent - and some of the recipients are getting them, but the same one person every once in awhile stops getting them in her inbox. I’m wondering if there is something I’m missing on my end.
There are general suggestions, but every site is different and there are many reasons this may not be working for you. If you start with the support ticket, they can give you the logging instructions and interpret the messages you have about notifications. In most cases, the issue is not with Gravity Forms, but with the configuration of your notification, or an issue with your mail server (which may not like something about your notification.)
