SendGrid with Non-Member User

I have integrated the SendGrid API into my website.

I use the API to send an e-mail whenever my “Help and Support” form is submitted.

The algorithm works perfectly - IF, I’m using the website as a user who is logged in -
if however, I try to use the form as a non-logged-in user, no e-mail is sent.

Any suggestions?

Good day,

I found the solution this morning.

The WebModule that I used to implement the functionality, had restrictive permissions (members only) set.
After changing this to “Anyone”, it worked for non-logged-in users.
