Start a newsletter and build a following in Singapore

· 8 min read · By Leo Tan

To start a newsletter and build a following, pick one narrow topic, choose a simple email platform, publish on a fixed schedule, and grow it where your readers already gather. This guide walks through each step for a Singapore audience, including the local email rules most guides skip.

Most newsletters die at issue three. Not because the writing was weak, but because the writer chose a topic they could not sustain and a schedule they could not meet. Get those two decisions right and the rest is repetition. Everything below is ordered the way you should actually do it, not the way it looks impressive.

Pick a topic narrow enough to own

The fastest way to lose readers is to write about everything. A newsletter that covers career tips one week, crypto the next, and travel after that gives nobody a reason to stay subscribed. Pick one clear subject you can talk about for a year without running dry, and one clear reader you are writing for.

A useful test: finish the sentence "a newsletter for ___ who want to ___." For example, "for poly students who want to break into UX design" or "for young Singaporeans who want to understand their CPF." The tighter that sentence, the easier every future issue becomes, because you already know who is on the other end and what they came for.

Knowing your reader is a writing skill, not a guess. The University of North Carolina Writing Center has a plain guide to writing for an audience that maps neatly onto newsletters: work out what your reader already knows, what they want, and what tone lands with them before you draft a word. If your sentences ramble, tighten them first by working through how to improve your business writing skills, because clear writing is the whole product here.

Choose an email platform, not a social feed

A newsletter lives in inboxes, not on someone else's feed. That distinction matters: a platform where you own the email list means an algorithm change cannot wipe out your reach overnight. Start with a tool that is free at small scale and lets you export your subscribers whenever you want, so you are never locked in.

You do not need the most powerful tool. You need one you will actually open every week. Here is how the common options compare for a beginner in Singapore, all of which accept overseas sign-ups and Stripe payouts.

PlatformFree tierBest forBuilt-in paymentsExport your list
SubstackUnlimited subscribersWriters who want zero setupYes (paid tiers)Yes

MailerLiteUp to 1,000 subscribersDesign control, automationsAdd-onYes
GhostTrial only, then paidOwning your own site and brandYesYes
Kit (ConvertKit)Up to 10,000 subscribersCreators building sales funnelsYesYes

Pick one and move on. Switching platforms later is easy because your list exports as a file. What you cannot get back is the three weeks you spent comparing features instead of publishing.

Set a cadence you can keep

Readers forgive a small newsletter. They do not forgive an unreliable one. A weekly issue that lands every Tuesday builds more trust than a brilliant one that shows up whenever you feel inspired. Consistency is the signal that tells a subscriber you are worth staying with.

Be honest about your capacity. If you are a full-time student or serving NS, fortnightly or monthly is a real commitment you can hold, and holding it beats promising weekly and vanishing. Write your first four issues before you launch, so the early weeks run on a buffer instead of panic. Once those four are out, you will know from experience how long an issue really takes you.

Tell readers the cadence on your sign-up page and then honour it. "A short issue every second Sunday" sets an expectation you can meet. "Frequent updates" sets one you cannot.

Get your first 100 subscribers

Nobody subscribes to an empty newsletter, so your first readers come from people and places that already know you. Start with your own contacts: message the people who genuinely fit your reader description and ask if they want in. A personal invite converts far better than a public post, because there is a face and a reason behind it.

After your warm list, go where your readers already spend time. In Singapore that means relevant Telegram groups, Reddit threads like r/singapore, LinkedIn if your topic is career or business, and niche community pages. Show up useful first: answer questions, share one genuinely helpful thing, and link your newsletter only where it directly answers what someone asked. The full playbook for this sits in our guide to growing an audience online as a beginner, and the same rules apply to a newsletter.

Two habits compound quickly. Put a one-line sign-up link in your social bios and email signature so every conversation can turn into a subscriber. And ask readers to forward each issue to one person who would like it, then make that easy by keeping issues short and shareable. Referrals from real readers cost nothing and bring people who already trust the person who sent them.

Stay on the right side of Singapore's email rules

Sending a newsletter in Singapore is legal and simple, but two rules apply the moment you email people. Learn them once and you never have to worry again.

First, the collection of email addresses. Under the Personal Data Protection Act, an email address tied to a person is personal data, so you need clear consent to collect and use it for your newsletter. The Personal Data Protection Commission explains the Personal Data Protection Act and the consent and purpose rules in plain terms. In practice this means a real opt-in, not a pre-ticked box, and using the addresses only for what people signed up to receive.

Second, the messages themselves. Bulk commercial email in Singapore falls under the Spam Control Act, which IMDA administers. It requires a working unsubscribe option, an accurate subject line, and your sender details in the message, and an unsubscribe request must be honoured within ten business days. IMDA sets out the Spam Control Act requirements in full. Every reputable email platform includes a compliant unsubscribe link by default, so following the rules mostly means not disabling it and not buying lists of strangers.

Monetise after you have trust, not before

The order that works is audience first, money second. A newsletter with 200 readers who open every issue is worth more than one with 5,000 who ignore you, because engaged readers are the ones who eventually pay, refer, or hire you. Chasing revenue on day one usually costs you the trust that revenue depends on.

When you do monetise, keep it honest and tied to the value you already give. Paid subscriptions for deeper content, a small sponsorship from a brand your readers actually use, an affiliate link to a tool you genuinely recommend, or your own product or service. Whatever you pick, tell readers plainly when something is sponsored. One misleading plug can undo a year of trust, and trust is the only asset a newsletter really has.

Newsletter setup checklist

Run through this before you send your first issue. Each step takes minutes, and skipping them is what turns a promising start into a false one.

StepWhat to doWhy it matters
Define the readerWrite your "for ___ who want to ___" sentenceEvery future issue gets easier to write
Pick a platformChoose one free tool and create the accountStops you comparing features for weeks
Set the cadenceDecide weekly, fortnightly, or monthlyReliability builds more trust than volume
Write a bufferDraft your first four issues before launchEarly weeks run calm, not in a panic
Build the sign-up pageState the topic, reader, and cadence clearlyHonest promises get honest sign-ups
Check consent and unsubscribeReal opt-in, working unsubscribe linkKeeps you compliant with PDPA and the Spam Control Act
Invite your warm listPersonally message people who fitFirst readers convert best from real invites

Working through a checklist like this with people who have done it before saves months of trial and error. That mentorship is a big part of what you get in a FINternship masterclass, alongside other young Singaporeans building their own projects.

Frequently asked questions

How many subscribers do I need before a newsletter is worth it?

Fewer than you think. A hundred readers who open and reply is a real following, and enough to test sponsorships or a paid tier later. Focus on open rate and replies over raw subscriber count, because a small engaged list beats a large silent one for almost every goal you might have.

Do I need to register a business to run a paid newsletter in Singapore?

Not to start a free one. Once you earn regular income from paid subscriptions or sponsorships, you should register with ACRA and declare the income, the same as any side income. Registration is quick and inexpensive, and you can begin free while you build readers, then formalise things when money starts coming in.

How long before a newsletter starts to grow?

Expect slow months at the start. Most newsletters grow in steps: a quiet stretch, then a jump when one issue gets shared widely or you show up in the right community. The writers who succeed are the ones still publishing at month six, when the compounding finally shows, so treat the first few months as practice rather than a verdict.

Starting a newsletter is one of the cheapest ways to build a real audience and a genuine skill at the same time. If you want structure, honest feedback on your writing, and a room of other young Singaporeans shipping their own projects, that is exactly what a FINternship apprenticeship is built for.
