How can I change this: when users get the result from a form, the email sender they see is this: [email protected] This is not customer friendly. Can I get my own email address in here somehow?

Answer:

If you don't want to receive email through FormNX SMTP then you can add your own STMP settings and use that email SMTP to send emails.
Please check out this documentation: https://formnx.com/details/docs/features/email-... to know how you can add your own email SMTP settings and choose that email SMTP to send email notifications
