Hi bttmrc,
I think you’re asking how to set the “From Email” email setting from a magic tag. If your goal is to be able to reply to the person who submitted the form, you can use a magic tag in the “Reply To Email” to setting.
If you set the “From Email” setting to a magic tag, and I filled out the form, the email would appear to becoming from my email address, but sent by your server, which looks like a phishing attack to Gmail, Exchange or other clients, so they will most likely not deliver it. You could try it, but if you are not using Caldera Forms Pro, it’s important you set the DKIM and SPF DNS records on the domain you are sending as, or your contact form emails could go to spam or be marked as phishing scams.
We help people with email deliverability issues all the time, and it’s gotten a lot more complex over the last few years. That’s why we built Caldera Forms Pro. It makes this all of this hassle invisible to you. You fill in your API keys in the Caldera Forms settings, and we take care of ensuring that your emails are delivered with the “from” message as whatever you wish, spam is blocked and the messages look great.
