Kit vs Substack: Which One is Best For My Podcast?

In today’s episode, I answer the question: “Should I use Substack for my newsletter or something like Kit (formerly Convertkit)?” I explain that Substack is a good fit for people who primarily want to share their thoughts or report news to an audience, especially writers and journalists. You can set a premium price for subscribers, though Substack takes a percentage of your earnings.

Substack

Substack is a newsletter-first publishing platform built around simple creation and monetization of written content. It lets creators publish posts that go both to an email inbox and a web page, with built-in tools for paid subscriptions and community engagement (comments, chat, Notes).

Kit (formerly Converkit)

Kit (formerly ConvertKit) is an email-marketing platform designed for creators who want more control over audience relationships, automation, and monetization — not just basic newsletters. It includes advanced segmentation, automation workflows, and tools for selling digital products alongside newsletters.

Growing Your List

I talk about the low conversion rate for newsletter signups—typically only 3-5% of your audience might subscribe, and having a strong lead magnet helps increase that number.

Personally, I use my newsletter in a hybrid way: I share my thoughts on podcasting, updates on my latest content, things that have caught my eye, and a call to check out the School of Podcasting. However, if your main goal is marketing, Substack isn’t the best choice. Tools like Kit, MailerLite, and Beehiv are better for things like automated sequences, lead magnets, and selling advertising.

I also discuss how some platforms—like Riverside and Kajabi—offer podcast hosting, but I don’t recommend using services that aren’t specifically built for podcast hosting. If you’re considering a platform, always check if they offer important tools like 301 redirects for your podcast feed.

Got More Questions?

In summary, if you just want to inform and connect with your audience, Substack is an easy and free option. If you want to do marketing or advanced list-building, platforms like Kit or MailerLite are better suited.

If you need help with any of this, don’t hesitate to reach out or join the School of Podcasting, where you’ll find step-by-step courses, consulting, and a supportive community.

Speaker:

Dave, you always talk about how important newsletters are.

Speaker:

I see where I can get a substack for free. So should I use

Speaker:

substack for my newsletter?

Speaker:

So, substack and newsletters

Speaker:

and when to use what? Because my grandpa

Speaker:

told me, any job is easy if you got the right tools,

Speaker:

but painting with peanut butter is not what I

Speaker:

recommend. So substack. This is what I

Speaker:

see a lot of people having success with substack

Speaker:

are doing. That is if you are,

Speaker:

let's say. I know at the beginning it was a lot of reporters

Speaker:

who either a, didn't like

Speaker:

the fact that they had to report the news a certain way with

Speaker:

a certain lean, and they would get fired. And they're like, fine, I'm going to

Speaker:

go report the news over here. And then in theory, if

Speaker:

you have enough followers and people that want your content,

Speaker:

they will actually pay for it. And you get to set that price. And then,

Speaker:

of course, substack takes a percentage. And so it's for

Speaker:

people who are, you know, kind of pontificating.

Speaker:

Here are my thoughts. And there's nothing wrong with that.

Speaker:

And another thing you want to keep in mind is about 3%

Speaker:

of your audience, if you're really good, will sign up for

Speaker:

your newsletter. You have to have some sort of what we call a lead magnet

Speaker:

often to get them to sign up. And even then

Speaker:

again, you're looking at about 3 to 5%

Speaker:

versus something like kit or

Speaker:

Mailer. Light Beehive is another one similar

Speaker:

to substack, where it's

Speaker:

primarily you're writing news. You're not so much

Speaker:

marketing to people, although you can.

Speaker:

So I'll give you an example. I have a substack and

Speaker:

I was just playing with it, and so I went over and said,

Speaker:

oh, my premium price will be whatever. And I woke up and had two

Speaker:

people. And I was like, oh, crap, now I gotta write premium stuff.

Speaker:

And so that doesn't mean, you know, that's gonna happen to

Speaker:

you. It might. I hope so. But my problem

Speaker:

is I want my newsletter to market my

Speaker:

school of Podcasting. And so I also had to

Speaker:

look at what can I do and sustain.

Speaker:

And so my newsletter is usually about three paragraphs about

Speaker:

whatever is on my mind in the world of Podcasting. And

Speaker:

then it's a here is what I've been up to. So

Speaker:

links to all the episodes and blog posts and videos that I've been doing.

Speaker:

And then it's here's what caught my eye, which is things I

Speaker:

saw on YouTube, whatever. It's literally exactly that. Things that

Speaker:

caught my eye. And then at the end it's like,

Speaker:

here's what's coming in the future, please tell a friend. Oh, by the way, if

Speaker:

you need help with your podcast, here's a link to the school of Podcasting.

Speaker:

And so I'm kind of using it in a hybrid way.

Speaker:

I'm not doing a ton of marketing. Like, for example, if I want

Speaker:

to give away a free PDF, Substack is not the place to do that.

Speaker:

That's more of a ConvertKit Mailer, like, kind of thing.

Speaker:

If I wanted to sell advertising in my

Speaker:

newsletter, that again, would not be a Substack thing, although you could do

Speaker:

it via third party. But that, again, is more of a

Speaker:

ConvertKit, definitely more of a Beehive kind of thing.

Speaker:

And so a Substack is a great place where

Speaker:

you want to communicate with your audience. Now, the other

Speaker:

thing is they're going to say, but, Dave, you could use them for your podcast.

Speaker:

And that is true. You could also use Riverside.

Speaker:

I'm trying to think who else has bolded on

Speaker:

Kajabi. You could use them. I am not a

Speaker:

fan of putting my podcast

Speaker:

on something that was not designated from day

Speaker:

one to be a podcast host. I work for

Speaker:

a company called PodPage, and there are many people that have

Speaker:

requested that we become an email service like

Speaker:

Mailchimp or ConvertKit or MailerLite. And we're like, that's not really our

Speaker:

jam. And there's a lot more to it. And

Speaker:

I like the people at Riverside, but when I

Speaker:

saw their podcast hosting solution, it was

Speaker:

definitely a minimalist, viable product in terms

Speaker:

of stats and other features, like, if you just need something to hit

Speaker:

play. Yeah. So consequently, I wouldn't use

Speaker:

Substack unless it was for, you know, Ms.

Speaker:

Marion's sixth grade class and it was just a thing they were going to do

Speaker:

for six weeks. Okay, maybe. But they don't need

Speaker:

the reliability. They don't need. You know what I mean? So

Speaker:

you want somebody who is majoring in podcasting as your media

Speaker:

host, not someone who was like, oh, we're a newsletter.

Speaker:

Oh, yeah. And we also do this podcast thing. So. And if you

Speaker:

are not sure, always ask them, can I get, and this

Speaker:

sounds very nerdy. Can I get a 301 redirect of my

Speaker:

feed. And I remember when Kajabi first came out. Now they have

Speaker:

since fixed this, but when they first came out and Kajabi is,

Speaker:

in my opinion, an overpriced course email,

Speaker:

all in one kind of service.

Speaker:

But they said, hey, we do podcasting now. And I'm like, great, do you do

Speaker:

a 301 redirect if I want to leave? And they actually

Speaker:

kind of went, huh? And I went, oh, yeah, no, no, no,

Speaker:

no, no. Now they have since fixed that and I still think they're

Speaker:

slightly overpriced. I'm a big fan of Heartbeat,

Speaker:

but at any rate, if you're not going to be doing any

Speaker:

marketing, I would use Substack. It is free.

Speaker:

Now, keep in mind, there are tools like Kit

Speaker:

and Mailerlite. Mailerlite is probably the more affordable one, but both

Speaker:

those have free plans up to about a thousand

Speaker:

subscribers. And a thousand subscribers is a lot

Speaker:

of subscribers. And what this enables you to do is

Speaker:

you can make a sequence. Now, a sequence is

Speaker:

a series of emails. Like, if you sign up,

Speaker:

I'll put a link to my, my

Speaker:

convert. I still call them ConvertKit, their real name is Kit, but I call them

Speaker:

Convertkit because they were convertkit for years. But if you want

Speaker:

to sign up, I'll put a link there and then you get a

Speaker:

welcome sequence which explains who I am, what I do.

Speaker:

It talks about the school of podcasting and it starts to market

Speaker:

to you because you've said, hey, I'd like to know more about you.

Speaker:

And then often let's do this. I will put a

Speaker:

link to. I have a lead magnets. That is the

Speaker:

podcasting best practices. I have a

Speaker:

podcasting, a podcast launch checklist. I'll put links to

Speaker:

those in the show notes. Then you can go over, sign up,

Speaker:

get your PDF and once you get your PDF behind the scenes, I'm going to

Speaker:

add you to my welcome sequence. And then if I ever decide

Speaker:

to run a campaign now, a campaign is simply a fancy

Speaker:

word for I'm going to try to get you to buy something. And so

Speaker:

I will explain how I'm going to save you time and money and how,

Speaker:

you know, you're just, this is the best thing since sliced bread.

Speaker:

That's a campaign. You really aren't supposed to do that. In Substack,

Speaker:

their rules are a little gray, but they kind of

Speaker:

hint that, like, this is more for writers than

Speaker:

marketers. And keep in mind you can do things like

Speaker:

that in Kit and in Mailerlite. And again,

Speaker:

there are many, many, many other

Speaker:

Things that you can choose from that are all email list tools and they

Speaker:

will let you do more marketing as well as send out just

Speaker:

an information email. When I looked up Kit

Speaker:

on the Internet you can send up to 10,000

Speaker:

subscribers for free where

Speaker:

MailerLite is 500 and you can

Speaker:

send up to 12,000 emails in a month.

Speaker:

So of those two, it looks like Kit is the better

Speaker:

free plan. You may have other tools I've used. Just for

Speaker:

the record, I use Sendfox, which is a

Speaker:

AppSumo product which means you pay one price

Speaker:

and then you can use it for life. It is a little slower

Speaker:

and as always you kind of get what you pay for and

Speaker:

if you use it on a regular basis, it's not bad. I used it

Speaker:

and kind of put it on hold for a bit and when I went to

Speaker:

resend to people who have been, you know, my followers,

Speaker:

it really took a while to kind of, as they called it,

Speaker:

warm up my list and I found that very, very

Speaker:

annoying. And so that might be a case where you get what you

Speaker:

pay for. So bottom line, should I use

Speaker:

Substack for my newsletter? Only if you plan

Speaker:

on just giving information. If you want to market, it's

Speaker:

not really the right tool, I would point you towards

Speaker:

ConvertKit. I do have an affiliate link, although if you're using the free

Speaker:

version, you know, I'm not sure how that's gonna work, but I'll put that in

Speaker:

the show notes along with if you want to see my lead

Speaker:

magnets. As always, if you need help with any of this stuff,

Speaker:

Speaker:
