Building an email list from zero starts with a small free offer (a lead magnet) that solves one narrow problem, placed somewhere your ideal buyer already spends time. Consistency matters more than size — a list of 200 engaged subscribers who trust you outsells a list of 5,000 who don't recognize your name.
A marketplace listing gets you buyers who are already searching. An email list gets you something a marketplace can't: a direct line to people who've shown interest, that you own and can reach any time, whether or not a search algorithm or marketplace feature decides to show your product that day.
Why a list matters even with a marketplace listing
Selling on a marketplace and building an email list aren't competing strategies — they work together. The marketplace brings in buyers actively searching for a solution; the email list lets you re-engage people who showed interest but didn't buy immediately, announce new products without starting from zero visibility each time, and build a relationship that makes someone more likely to buy your next product too, not just this one.
Start with a small, specific lead magnet
Almost nobody signs up for a generic "join my newsletter" anymore. What works instead is a lead magnet: a small, free resource that solves one narrow problem on its own, offered in exchange for an email address.
The most effective lead magnets share a few traits: they solve one specific problem rather than trying to be comprehensive, they can be consumed in minutes, and they naturally lead into the kind of paid product you eventually want to sell. A single template from a larger paid bundle, a short checklist version of a fuller guide, or a simple worksheet related to your main product idea all work well as a first lead magnet — you don't need to build something elaborate before you start collecting subscribers.
Where to find your first subscribers
The same places you'd look for your first buyers work for your first subscribers, often even better, since signing up for something free is a much smaller ask than paying:
- People who already know you — mentioning a free resource is a low-pressure way to start a list with people already inclined to trust you.
- Relevant online communities — subreddits, Facebook groups, and forums where your ideal buyer already asks questions related to what your lead magnet solves.
- Your marketplace listing itself — a line in your product description or a bonus resource offered to buyers is a natural, low-friction way to grow a list from people who've already shown real intent.
- Any existing content — a blog post, a video, or a social profile you already have is a free place to mention the lead magnet, rather than needing to build new distribution from scratch.
Tools that work with no budget
You don't need paid software to start. Most email tools (Mailchimp, MailerLite, ConvertKit, and similar) offer a free tier that comfortably covers the first several hundred subscribers, which is more than enough runway to validate whether list-building is working before spending anything on it.
What to actually send once people join
The most common mistake after someone joins a list isn't silence — it's the opposite: pitching a sale in the very first email. A short welcome sequence that delivers real value first — a tip related to the lead magnet, a bit of your own story, something useful on its own — builds far more trust than jumping straight to "buy my product."
After that, a simple ongoing rhythm works well for most sellers: mostly useful, standalone content, with occasional and clearly-flagged product news mixed in. People stay subscribed to lists that feel worth opening, not just ones that sell to them every time.
A list doesn't need to be big to be valuable — it needs to be made of people who actually open what you send, because they trust that it's worth their time.
A realistic first-month checklist
- Pick one narrow problem your ideal buyer has and build a small free resource for it
- Set up a free-tier email tool and a simple signup form
- Mention the free resource to people who already know you
- Share it in 2–3 relevant online communities
- Add a line about it to your marketplace listing description
- Send a short welcome email that delivers value before it sells anything
