I am sending my users a confirmation email. I see that the limit per hour is 1 email. Is there any way to upgrade my plan to be able to send more emails per hour? If not then how do I change my settings so that I can use another provider? my registrar is one.com and I use their email service. I read that I can update settings in zone editor but I do not know where to start. Is there any documentation on this? Many thanks
