How to Use Email Bundles to Grow Your List and Sell More Offers
TL;DR
Bundles are one of the most underutilized strategies for growing an aligned email list and selling your offers without living on social media. This post breaks down how bundles work for both hosts and contributors, why specificity determines whether your subscribers actually buy, and what to do after the bundle closes to turn new contacts into paying clients.
Last year I had 145 people sign up to my list through one single bundle hosted by my friend Kelly Sinclair. That was roughly 24% of her total bundle signups. From another bundle I participated in, the one hosted by my guest today, Allison Hardy, I had another hundred or so people come in. In total, I used three different lead magnets across various bundles throughout 2025, rotating between my AI-Powered Offer Confidence Checklist, trial versions of Grace the Offer Strategist, and Elliot the Offer Ecosystem Architect. All three performed well. People wanted them.
Here's the honest part: I didn't have a proper funnel on the backend of most of those bundles. I was testing, feeling things out, and mostly asking myself, is my audience interested in these resources? The answer was clearly yes. But interest and action are different things, and without a thoughtful email sequence following up, a lot of those new subscribers never went anywhere. That's the gap I'm closing now.
Bundles work. I've seen it firsthand, and in this episode I talked with Allison Hardy, an email marketing strategist who has hosted 15 bundles in two years and grew her list from 4,000 to 11,000 subscribers in the process. She also crossed 600 lifetime members in her membership, and she credits bundles as one of the main reasons she was able to do it. So this conversation goes deep on how bundles actually function as a strategy, not just a list-building tactic, and how to use them to move people toward your offers.
What Is a Bundle and Why Should You Care?
A bundle is a curated collection of free resources from multiple contributors, usually coaches, strategists, and experts in a related niche, offered to a shared audience in exchange for an email opt-in. The host organizes the bundle, recruits contributors, sets up the landing and resource pages, and promotes it to their list. Contributors provide a free resource and agree to promote the bundle to their own audience in exchange for exposure to the host's (and other contributors') lists.
Bundles do three things at once. They grow your email list with people who opt in specifically around a topic. They grow your visibility within a community of collaborators and their audiences. And, when the strategy is built correctly, they create an on-ramp to selling your offers. Those three outcomes can all happen from one well-run bundle.
Why Specificity Is the Deciding Factor in Bundle Results
The most important lesson from my conversation with Allison is this: the success of a bundle is determined by how specific it is, not how big it is.
Allison ran a bundle she called the AI Marketing Squad. It was timely. AI was everywhere, and she leaned into it. She had 2,500 people opt in. On the surface, it looked like a massive win. Then she ran the masterclass she always hosts after her bundles close, the place where she actually makes the offer. Two people bought.
The problem wasn't her masterclass. The problem was that the bundle attracted people who were curious about AI broadly, not people who wanted to buy an email marketing membership. There was a mismatch between who showed up and what she was offering next.
Contrast that with her bundle called Emails That Make Bank, which she runs around the specific topic of email strategy. That bundle typically draws around 800 signups. Less than a third of the AI bundle's numbers. But the conversion rate? Much higher, because the people who opt in are genuinely interested in email marketing, which is exactly what Allison sells.
Smaller, targeted lists beat larger, scattered lists every time. This applies to bundles in exactly the same way it applies to anything else in your business. If you are contributing to a bundle, the resource you offer should be directly relevant to your paid offers. If you are hosting a bundle, the title and theme should be clear enough that the right people self-select in and the wrong people scroll past.
How to Choose the Right Bundle to Participate In
When you are evaluating whether a bundle is worth contributing to, the question to ask is not "will this grow my list?" The question is "will this grow my list with the right people?"
Here is what that actually means in practice. Look at the bundle's title and theme. Does it clearly describe the same problem your paid offers solve? If you are an offer strategist and you are being invited into a bundle about Instagram growth, that is a misalignment. The people who opt in for Instagram advice are not in the same buying mindset as the people who need what you actually sell.
Look at the other contributors. Are they working with a similar audience or serving a complementary need? If the lineup of contributors reads as coherent, if there is a thread connecting the work everyone does, that is a signal the audience will be aligned.
And look at your own resources. Allison's point here is worth sitting with: the resource you contribute should be specific enough to function as a positioning signal. A broad freebie attracts broad interest. A narrow, highly specific resource attracts the exact person you want on your list.
How to Find Bundles Worth Joining
If you have never participated in a bundle and are not sure where to find them, Allison's answer is simpler than most people expect.
You are already on other people's email lists. When bundle promotions land in your inbox, notice them. Reach out to the host and ask to be included in the next one. Join networking communities where bundle hosts share opportunities.
And once you start participating, word spreads. Contributors get on hosts' radars. Hosts get on other hosts' radars. The more you participate, the more visible you become as a collaborative partner.
What It Actually Takes to Host a Bundle
I asked Allison directly about the overwhelm factor, because when I look at a bundle like Kelly Sinclair's with 50-plus contributors, my first reaction is: that looks like a lot. Allison's answer was grounding.
The first time you host a bundle, yes, there is more lift. You are building the systems from scratch. But Allison's rule of thumb is approximately 40 contributors for a focused, topic-specific bundle. At that scale, she typically sees around 1,000 signups. For broader bundles where the goal is volume, she goes up to 100 or more contributors.
Her process runs roughly like this. Month one is outreach: she spends about an hour a day for two weeks identifying potential contributors through her warm network, Instagram hashtag searches, recommendations from current contributors, and Google. Applications come in through a Google Form, tagged in her email system via Zapier, and she reviews them all. Then she sends acceptance emails, intake forms, and begins building the resource page.
The most time-intensive part is the resource page. Allison estimates about 10 hours to do it right: confirming all links, checking for mobile responsiveness, matching the correct image to each contributor, reviewing everything before sending it to contributors to check. After that, her promotional system takes over. Each contributor receives email swipe copy and is required to send one dedicated promotional email to their list during the bundle window.
The most important thing to build first is the system. Once you have hosted one bundle, the second is dramatically easier because you are refilling a template, not building from scratch.
The Metric That Actually Measures Bundle Success
If you are hosting a bundle, the number of signups is not the success metric. The success metric is what happens after.
Allison always follows her bundles with a masterclass. The masterclass is where she makes an offer. For her, the goal of a well-run bundle is to put the right people in the room for that masterclass. 2,500 signups and two buyers is not success. 800 signups and a solid masterclass conversion rate? That is.
For contributors, success looks different. Success is whether the people who came in from the bundle are your actual people. Did they open your welcome email? Did they engage with your follow-up sequence? Did any of them book a call, ask a question, or buy something? If not, either the bundle was misaligned or the follow-up was missing. Both are fixable.
What to Do With Your List After the Bundle Closes
This is where I have to be honest about my own mistakes. When Grace the Offer Strategist landed 150 new subscribers from bundle placements last year, I sent out one email checking in. Nobody responded. Nine people unsubscribed. I did not have a real follow-up sequence in place.
Allison's framing for what should happen after a bundle is "build the bridge." The bridge is the sequence of emails that moves someone from "I downloaded this free thing" to "I understand what this person offers and why it matters to me."
Here is what that bridge looks like in practice:
Start with reminders to actually use the resource. If someone downloaded Grace the Offer Strategist and never ran her, they are not going to magically become a buyer. Send them an email that says: here's why you should open Grace this week, here's what happens when you do, here's the link. Send it again. People are busy and distracted, especially if the bundle ran in December.
Include video if you have it. Allison specifically mentioned this. When new subscribers see your face and hear your voice, they move from "email subscriber" to "person I know." That shift matters in terms of how likely they are to open your next email.
Close the loop before opening a new one. Each time you send an email, you should be completing one cycle: here's the thing, here's why it matters, here's what to do next. Once that loop is closed, you introduce the next logical step. Not all at once. One thing at a time.
Ask for feedback. After they have had time to use the resource, send an email asking how it went. Give them a real way to respond, a simple form, a poll, an invitation to reply directly. This serves two purposes: it gives you useful data, and it deepens the relationship by showing you actually care what happened for them.
Is the Freebie-Seeker Problem Real?
I hear this concern a lot. You grow a list through a bundle and suddenly you have hundreds of people who were just there to collect free stuff and never intended to buy anything. Allison is honest about this: yes, some people come for the free content and nothing else. But her point is that this is almost entirely a function of specificity.
A broad bundle called something like "The Ultimate Resource Library" attracts people who want free things. A bundle called "Emails That Make Bank" attracts people who specifically want to learn email marketing. The second group may be smaller, but they are dramatically less likely to be collecting resources with no intention of going deeper.
Some people will still be freebie seekers even in a targeted bundle. Clean your list. Let them go. That is a normal part of how email marketing works. The goal is to build a list of people who genuinely belong there, not the biggest list you can accumulate.
Self-Assessment: Is a Bundle the Right Strategy for You Right Now?
Before jumping into a bundle, whether as a contributor or a host, it's worth being honest about whether the foundation is in place.
Do you have a lead magnet or free resource ready to contribute, and is it specific enough to attract your actual ideal buyer? A broad freebie will pull in a broad audience. That is not what you want from a bundle. The resource needs to be targeted enough that the person who downloads it is recognizably the same person who would eventually pay for your work.
Do you have an email sequence to follow up with new subscribers? Even a simple one, three to five emails with a clear job each, is enough to build the bridge. If you do not have that yet, build it before the bundle. A list you cannot follow up with is just a number.
Do you know which offer you want to lead people toward? The bundle's free resource and your paid offer need a logical through-line. If someone has to make a big cognitive leap to understand why they would hire you after using your freebie, the connection is too loose and the conversion will suffer.
Are you in communities where you can find bundles, be invited into them, or recruit contributors? This matters more than your list size. Relationships are how bundles get built.
If most of those are in place, you are ready. If several are not, the most useful move is to build the backend first. A bundle can grow your list quickly, but it cannot fix a strategy gap that exists before the subscriber arrives.
The Real Cost of Skipping the Follow-Up
Here is what actually happens when you grow your list through a bundle and do not have a follow-up sequence in place. The subscribers join. They download the resource or they do not. They get your welcome email or they do not open it. And then nothing happens. No follow-up. No bridge. No next step.
Over time, those subscribers become cold contacts. They forget who you are. They stop opening your emails. They eventually unsubscribe, or worse, they stay on your list and drag down your deliverability without ever engaging. The bundle worked. The lack of follow-up undid it.
The cost is not just lost subscribers. It is lost momentum. You did the hard part, you made the offer, you created a resource, you promoted it, you attracted real humans who were curious enough to say yes. And then you left them there with nothing to do next.
I say this from personal experience, not from a theoretical position. My Grace bundle results told me something valuable: people want this resource. What I did not do was honor that signal with a proper sequence. That is a fixable problem. But it has to actually be fixed.
Frequently Asked Questions About Using Bundles to Grow Your List
How many subscribers can you realistically expect from participating in a bundle?
It varies, but Allison's experience shows that active contributors typically see anywhere from 100 to 400 new subscribers from participating in a well-run bundle. The range depends on how aligned your resource is with the bundle's theme, how actively the host promotes, how many contributors send to their own list, and the size of the overall bundle. My own experience: 145 signups from one bundle, around 100 from another. Neither number changed my business on its own, but both added aligned people to my list who were genuinely curious about my work.
How do you know if a bundle is worth contributing to?
Look at the theme and the title first. Ask: are the people this bundle is designed to attract the same people who eventually buy from me? Then look at the contributor lineup. Are they working with a similar or complementary audience? Finally, consider whether your lead magnet is specific enough to be a good fit. A strong resource in a misaligned bundle will still underperform because the audience is not looking for what you sell.
What is the difference between hosting and contributing to a bundle?
As a contributor, you provide a free resource, agree to promote the bundle to your list at least once, and in return gain exposure to the host's audience and all other contributors' audiences. Your list growth is capped by how many people find your resource compelling within the broader bundle. As a host, you organize the full bundle, recruit contributors, build the landing and resource pages, and own the entire opt-in list. Every person who signs up for the bundle goes on your list, not just the people who downloaded your specific resource. Hosting is more work upfront, but the return on list growth is significantly higher.
Do you need a big list to host a bundle?
No. Allison's first bundle goal was 500 people. She had a list of 4,000 at the time. She hit 1,250 signups. The list growth comes from the collective promotion of all your contributors, not just your own list size. What matters more than list size is the quality of your contributor network and how actively they promote. A smaller host with 30 engaged contributors who all send to their list will often outperform a larger host with 60 contributors who do not.
How do you deal with contributors who do not promote?
Allison is clear in her requirements upfront: one dedicated solo email to their full list during the bundle window is mandatory. She includes it in the application, the intake form, and every email she sends to contributors. Even so, some people do not follow through. Her approach is to communicate the requirement clearly and repeatedly, then release attachment to who does or does not comply. If someone is consistently unresponsive or difficult, she does not invite them to future bundles. UTM tracking links can help you identify who is actually driving traffic if you want to be more precise about it.
How soon after a bundle should you send follow-up emails?
As soon as possible, and with more frequency than feels comfortable. Allison specifically noted that December bundles are tricky because people are distracted. If your bundle ran in December, consider sending your first follow-up email in early January when people are back at their desks and paying attention. After that, a sequence of three to five emails over two to three weeks, each with one specific job, is a reasonable starting point. The goal is to move them from "downloaded a free thing" to "understands what this person does and has a clear next step."
What should the resource be that you contribute to a bundle?
It should be the most useful, specific thing you can offer that is directly connected to what you sell. Not your most general freebie. Not something designed to appeal to everyone. Something that would only make sense to the exact person who would eventually benefit from your paid work. Grace the Offer Strategist made sense in offer-focused bundles because anyone who wanted to run Grace and get value from her was clearly in the market for offer strategy support. That specificity is a filter, and filters are valuable.
What offer should you lead people toward after the bundle?
The offer that logically follows from the free resource they downloaded. If someone grabbed a checklist about sales pages, the next step might be an audit of their sales page. If someone downloaded a GPT that helps them map their offer ecosystem, the next step might be a sprint or a studio engagement where you do that work together. The key is that there should be a clear, logical bridge between the free thing and the paid thing. If someone has to make a big cognitive leap to understand why they would hire you after using your freebie, the connection is too loose and the conversion will suffer.
What's Next?
If this conversation has you thinking seriously about bundles, the first thing worth doing is making sure your offers are clear and connected enough to actually benefit from new subscribers. A list full of curious, aligned people will only convert if there is a clear next step for them to take.
If you want to make sure your offer is ready before you start driving traffic to it, the OfferMojo 6-Pillar Offer Audit is a good place to start. It is a 60-minute done-with-you diagnostic that looks at your offer across all six pillars, strategy, structure, ecosystem, messaging, visibility, and sales, and gives you a written scorecard and prioritized action plan within three to five days.
