I would actually like to build off of this if I could.
I want to be able to send an email and within that email have a button that my client can press which will send back another email to me with 3 more buttons I can press basically saying yes, no, maybe which will then be sent back to my client.
I also want the subject to remain the same so I can track the hundreds of daily emails. If every single email had the same subject this wouldn't save me time.
I feel like this has to be possible, but the coding looks like it may be more difficult than I was initially thinking.
