A podcast invitation competes with everything else in someone's inbox, and most of them lose. Not because the show is too small, but because the email reads like a request for a favour: "I'd love to have you on, let me know if you're interested." The person has no idea what the show is, who listens, what they'd talk about, or how much of their time you're asking for. So they do the easy thing and don't reply.
Here's the version that gets answered, and what to do when it doesn't.
Before you write a single email
Pick guests you can say something specific about. "I've followed your work for years" is invisible; "your post last week about pricing experiments is exactly the argument I keep having with my co-founder" is a reason to reply. If you can't write one specific sentence about why this person, for this episode, you're not ready to invite them. Ten minutes of guest research before outreach pays for itself in reply rate.
Then decide what you're actually offering. Even a small show has something: a focused audience, a well-edited clip they can post, a conversation about the topic they want to be known for. Lead with that.
The invitation, line by line
Keep it under 150 words. Every line does one job.
- Subject line: their topic, not your show. "Pricing experiments, on the record?" beats "Podcast guest invitation" every time.
- Line one: the specific thing that made you think of them. One sentence, no flattery padding.
- Line two: what the show is and who listens, in plain numbers. "A weekly interview show for first-time SaaS founders, about 1,200 downloads an episode" is honest and useful. Small numbers with a clear audience beat vague claims of reach.
- Line three: the angle. Name the two or three things you'd want to talk about. This is where your research shows, and it tells them the conversation will be worth their time.
- Line four: the ask, with the cost made small. "45 minutes on a video call, any weekday afternoon in the next three weeks. We handle editing and send you a clip to share."
- Close: one question they can answer with a yes. "Would a slot in early October work?"
That's the whole email. No bio paragraph, no list of past guests unless one of them is genuinely relevant, no "I know you're busy."
The follow-up cadence
Most yeses come on the second or third touch, so the follow-up matters more than the first email. Four touches over about three weeks, then stop.
- Day 0: the invitation above.
- Day 4: a two-line reply to your own email. Add one new thing: a question you'd ask, or a clip from a recent episode that shows the format. Never "just bumping this."
- Day 10: switch channel. A short LinkedIn or X message that references the email, so it reads as persistence rather than spam.
- Day 20: the close-out. "I'll stop here so I'm not cluttering your inbox. If the timing's ever better, the door's open." This one gets a surprising number of replies, because it removes the pressure.
If there's still nothing after four touches, move on and put them on a list to try again in six months with a fresh angle. Chasing beyond that costs you more goodwill than it earns.
When they say yes
Reply within a day with everything they need in one message: the recording date and link, how long it runs, the three topics you'll cover, and what you need from them (a headshot, a short bio, how they want to be introduced). Send a short reminder two days before with the same link. Guests who feel organised show up relaxed, and relaxed guests give better interviews.
When they say no
Thank them, ask if there's someone they'd recommend instead, and mean it. Referred guests reply at several times the rate of cold ones, and "your colleague suggested I reach out" is the strongest opening line you can have.
The numbers to expect
For a small show doing careful, specific outreach, a reply rate of 30 to 40 percent and a yes rate of 15 to 25 percent is realistic. If you're well below that, the problem is almost always the first line or the ask, not the size of your show. Rewrite those two before you send more.
