Why are my double opt-in confirmation emails going to spam?

Double opt-in confirmation emails may go to spam if your account's default From Address is a free mailbox provider, like @gmail.com, @yahoo.com, @aol.com, etc. To update your account's default from address, navigate to Account > Contact Information > Organization and update your Default From / Reply-To address. You can set up a forwarding address if you don't already have a business email associated with your domain. For example, if your default From Address is a Gmail address, you can set up an alias to have emails forwarded from your public From Address to your personal inbox.
