We are currently working on multiple podcasts for a single-user functionality for our platform and expect it to be ready very soon. In the meantime, an easy workaround will allow you to have more than one podcast.
If you are using a gmail.com address, you can add the name of your podcast with the "+" character to always use the same email address. Important: this trick is only valid with @gmail and @hotmail addresses.
For example, if your email is firstname.lastname@example.org, you can use the email email@example.com and all emails will be sent to the email address firstname.lastname@example.org.
For a limited time when a customer creates a second account with RSS.com, we are granting a 30% discount for 1 year. To take advantage of this offer, simply create a new account and email us (email@example.com) to let us know you've successfully created the account.
