Do different shows need separate email accounts or SMTP setups?
No. All shows use the same site-wide SMTP connection — you configure it once using a plugin like WP Mail SMTP or Fluent SMTP, and every show’s emails go through it.
Each show sends with its own From name — subscribers see the show name in their inbox, not your site name. The From address is whatever your SMTP plugin is configured to send from, which is a single site-wide setting shared across all shows.
If you need to send from a different address per show — for example, separate domains — that’s possible using the benecaster_email_from_address filter hook, but requires code and your SMTP provider configured to authorize multiple sending addresses.
