How to grow a podcast email list with a spoken keyword

Most of your listeners hear your call to action while they're driving, walking the dog, or doing the dishes. "Head to our website and sign up for the newsletter" asks them to remember a URL until they're home, and few of them will. If you want to grow a podcast email list, the ask has to be something a listener can remember with their hands full and do in a few seconds later.

A spoken keyword is that ask. You say one word and one number on the show. When the listener parks, they text the word, a short conversation asks for their email, and the show notes or bonus you promised arrives by text and email. They join your list in Mailchimp, Kit, or ActiveCampaign, tagged with the episode.

Why "link in the show notes" stalls

The show notes are three taps deep in a podcast app. The listener has to stop what they're doing, find the episode, scroll the description, and tap a link that opens a form. Each step loses people, and listeners on a commute can't do any of them safely.

"Find us on Instagram" and "join our Discord" send listeners to places where the platform decides who sees your next post. An email list is the audience you keep if a platform changes its rules.

How to say a keyword so people remember it

Pick a word that's easy to spell when heard. NOTES, PLAYBOOK, or your show's one-word name works. Avoid words with homophones and anything that needs spelling out more than once. Then say it twice:

"If you want the full list of books from today's episode, text NOTES to 33777. That's NOTES, N-O-T-E-S, to 33777. I'll text you the list."

Keep the number the same in every episode. Listeners who hear it weekly start to remember 33777 on their own. Keywords are unique on each short code, so if your word is taken on 33777, check 55444 and use that one consistently. Put the ask near the part of the episode it relates to, and again at the end. A mid-roll mention tied to what you just discussed makes more sense than a generic plug in the intro.

What to offer listeners

How many listeners respond depends most on what you offer, and the strongest offers are tied to what they just heard:

• The show notes or resource list for this episode
• A bonus episode or extended interview
• A worksheet or template you talked through
• A transcript of a popular episode
• Early access to tickets for a live taping

A generic "join the newsletter" ask gives the listener nothing to want right now; what to offer for texting in has more ideas.

How to set it up in Textiful

1. Get your keyword. Pick one in Keywords on 33777 or 55444. One keyword is included on your plan, and more are $10/month each.
2. Start from "Give away a download." Upload the file once in Handouts and reuse it in any flow.
3. Ask for an email, and stop there. Across Textiful flows over 90 days in 2026, one-question flows were completed 89.5% of the time and two-question flows 83.1%. If you want a first name too, ask for it second.
4. Deliver it twice. "Text a handout" puts it on the listener's phone now, and "Email a handout" puts it in their inbox for later. Handout emails come from your name, and replies come back to you.
5. Hand off to your list. Add "Add to Mailchimp" or "Add to Kit" (ActiveCampaign and HubSpot work too), and "Tag the contact" with the episode. Your email tool's welcome sequence takes it from there.

See which episodes worked

The simplest setup is one keyword for the show and a tag per episode. Switch the tag in the flow when a new episode goes out, and the Reports page shows how many contacts each tag picked up.

If you want cleaner numbers, give a series or a sponsor read its own keyword. Each keyword has its own row on the Reports page, with text-ins, new contacts, and completion, and "Compare two keywords" shows how many people texted one, the other, or both.

For the video version, put a free QR code on screen during the call to action. The QR code and the keyword can each start a copy of the same flow, so you'll see how many came from video and how many from audio. QR code or keyword? explains the trade-off.

Live tapings

At a live show you have a room and a screen, so treat it like a talk. Put the QR code on the screen, say the keyword, and run a live poll during the episode. The results page shows counts and percentages on screen, never names, and the vote and the email can come in the same conversation.
