Can I only use the e-mail I used to sign up for my account as an SMTP?

Hello Zach,

Thanks for reaching out to Jotform Support. Yes, you can use the email address you used when signing up for your Jotform Account as an SMTP Sender Email Address, and you can also use any email from your company that you have access to. You just need to check with your email service provider about the availability and the correct setup if you want to add your account/company email address as an SMTP. In addition, you might also want to check out this guide about How to Set up SMTP for a Form.

Give it a try and let us know if you need any help.
