Grow your podcast email list with a spoken keyword
To grow a podcast email list, give listeners a call to action they can act on while their hands are full: a keyword like NOTES and a short code they can text. They text it, give an email, get the show notes or bonus you mentioned, and join your email list.
Updated November 5, 2026
Most of your listeners hear the 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 call to action has to be something a listener can do in the moment, with one free hand and without looking at a screen for long. This page covers how podcasters use a spoken keyword, what to offer for it, and how to measure which episodes bring people in.
Why do "check the link in the show notes" asks stall?
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" move listeners to a place where you don't control whether they see your next post. An email list is the audience you keep if a platform changes its rules.
A keyword collapses the steps into one: text a word to a number. It's short enough to remember from the car and quick to do once they've parked, or at home ten minutes later.
How do you say a keyword out loud 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. 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 will 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.
What should you 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, sent as a handout
- 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 has nothing for the listener to want right now. What should I offer people for texting in? goes further.
How do you set it up?
- Get your keyword. Pick one in Keywords on 33777 or 55444. One keyword is included on your plan, and nobody else on Textiful can use it on that short code.
- Start from "Give away a download." Upload the file once in Handouts.
- Ask for an email, and stop there. Listeners are often mid-task. One question is enough for most shows. If you want a first name too, ask for it second.
- Deliver it twice. "Text a handout" for the listener on their phone now, and "Email a handout" so it's in their inbox later when they're at a desk. Handout emails come from your name and replies are forwarded to you.
- Hand off to your list. "Add to Mailchimp" or "Add to Kit," and "Tag the contact" with the episode. Your email tool's welcome sequence picks it up from there.
How do you know which episodes worked?
Each flow has one trigger and reports on its own. The simplest setup is one keyword for the show and a tag per episode, set by switching the flow's tag when a new episode goes out. If you want cleaner numbers, give a series or a sponsor read its own keyword and compare them in the keyword activity report, which also shows the overlap between two keywords.
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 versus audio.
Live tapings are the exception
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 and never names, and the vote and the email can come in the same conversation.
Before and after
| "Link in the show notes" | With Textiful | |
|---|---|---|
| What the listener does | Find the app, the episode, the link, the form | Text one word to 33777 |
| From the car | Hard to remember by the time they park | One word and one number, easy to remember later |
| Delivering the bonus | A landing page and a confirmation email | Sent by text and email when they finish |
| Which episodes worked | Hard to tell | A tag per episode, or a keyword per series |
| Where they end up | Your email tool, if they finish the form | Mailchimp, Kit, ActiveCampaign, or anything on Zapier |
Who this is for, and who should skip it
This fits podcasters with a mostly US audience who already have an email tool and want a call to action that works without a screen. It's especially useful for interview shows and how-to shows, where the episode naturally produces a resource list.
If most of your listeners are outside the US, a web link will reach more of them. If you publish one episode a quarter, you'll use few conversations, so the smallest plan should cover you. Your first keyword is included, and yearly billing gives you the year's conversations up front to use whenever an episode drops. Plans start at $19/month; see pricing.

Questions people ask
Near the point in the episode that the offer relates to, and again at the end. A mid-roll mention tied to something you just discussed tends to make more sense to listeners than a generic plug in the intro.
One keyword for the show is easiest for listeners to remember. If you want to know which episodes drive sign-ups, add a second keyword for a specific series, or a free QR code per episode on the video version.
Only where there's a screen: the video version of your show, a clip on social, or a slide at a live taping. For audio, the spoken keyword is the call to action.
The flow runs again for them. A new start counts as a new conversation, and your handout is still there to send.
The short codes are set up for US mobile carriers, so it suits shows with a mostly US audience. For a global audience, keep a web sign-up link as well.

How to turn a room into contacts you can follow up with: what to offer, how to ask from the stage or the booth, what to ask for, and what to do in the 24 hours after.
ReadKeyword (texting)
In texting, a keyword is a word someone texts to a short code to start a specific program, such as SLIDES to get a slide deck or JOIN to sign up for a list. On a shared short code, the keyword tells the system which organization and which program the message belongs to.
ReadShort code
A short code is a five- or six-digit number that organizations use to receive and send text messages at volume, most often for text-to-join sign-ups, voting, and requests for information. Mobile carriers review each short code program before it goes live.
ReadLead magnet
A lead magnet is something useful offered for free in exchange for a person's contact details, usually an email address. Common examples are slide decks, checklists, guides, templates, recordings, and discount codes.
ReadEmail service provider (ESP)
An email service provider (ESP) is software that stores an email list and sends emails to it, such as newsletters, welcome emails, and automated follow-ups. ESPs also handle sign-up forms, unsubscribes, and delivery. Mailchimp, Kit, and ActiveCampaign are examples.
ReadWebinar audience engagement by text
Webinar audience engagement by text puts the phone next to the laptop to work: viewers scan a QR code on your slide or text a keyword, vote in a live poll, and give an email in the same conversation. You screen-share the results page, and every voter lands in your list.
ReadHow speakers collect audience emails after a talk
The way to collect emails from your audience after speaking starts at the beginning of the talk: tell the room the slides are coming, so they can put their phones down. On the last slide, ask them to scan a QR code or text DEMO to 33777. Textiful asks for an email, sends the deck, and adds the contact to your email list.
ReadCollect fan emails at concerts and shows
The easiest way to collect fan emails at concerts is to say a keyword from the stage between songs and put a QR code on the merch table. Fans text FANS to 33777, give an email, and get the unreleased track or setlist you promised, and they land in your email list before the encore.
