How do I add a newsletter sign-up to my podcast website?

You can add a newsletter sign-up form to your Transistor podcast website, so listeners can join your mailing list right from your website. New sign-ups are added to your email marketing app automatically.


Which email apps work with Transistor


  • Kit
  • Mailchimp
  • MailerLite
  • ActiveCampaign
  • Klaviyo
  • Drip
  • HubSpot


You can connect one email app to each podcast.


How to connect your email app


  • Go to the Integrations tab of your podcast and find Mailing Lists & Newsletters
  • Click the Connect to button for your email app:
    • Mailchimp, Drip and HubSpot: sign in to your account and allow access
    • Kit and MailerLite: paste in your API key from your account
    • ActiveCampaign: paste in your API URL and API key, from Settings > Developer in ActiveCampaign
    • Klaviyo: paste in a private API key with read and write access to Lists, Profiles and Subscriptions
  • Choose where new subscribers go, like a list, group, form or tag, depending on your email app
  • Click Save


With MailerLite, Transistor shows whether double opt-in is on in your MailerLite account. If it's on, new subscribers get a confirmation email first.


Customize your sign-up form


Your sign-up form appears on your podcast website once your email app is connected. To change its wording, go to the Website tab, open Website Settings and find Newsletter Sign Up Form:


  • Newsletter sign up headline: for example, "Join our newsletter"
  • Newsletter sign up intro text: an optional line below the headline


Newsletter sign-ups aren't available for private podcasts.


Send your episodes to your email list


Using Kit? You can also add a player for your latest episode to your Kit emails.
