I'm now getting desperate. After weeks of futile attempts to get the SendGrid API code working for my website unico.org, I am still unable to reliably send email messages from a database form. While I was able to send test messages, others who tried got no response. Unless this is a "gotcha" which can only be remedied by a SendGrid upgrade I clearly need an alternative method.
I need a way to do this in Wix. I have an unhappy-rapidly-moving-to-angry client who is putting the screws to me to get this working. Please provide the necessary code examples for how this can be done ASAP.
