You do not need a big list to start building real email income. You need a platform that costs you nothing while you have 50 subscribers, lets you set up a welcome sequence in a weekend, and does not send your messages to spam. Most “best email marketing software” roundups are written for online stores with large lists and large budgets, so they rank platforms on features you will not touch for months.
This guide ranks the options on what matters when you are just starting out. Let’s get you to a decision today.
Why Your Email List Is the One Asset Nobody Can Take Away From You
Every social platform sets its own rules. Reach drops when an algorithm changes, accounts get restricted, and a following built on someone else’s site can disappear with one policy update. You have no say in any of it.
An email list is different. The addresses belong to people who asked to hear from you, and you can export them from one platform and import them into another. If you outgrow your first tool, you take your subscribers with you.
For affiliate income, a list also does something a social post cannot. A post is seen once, by whoever happens to be scrolling. An email goes to everyone who opted in, and you can send a follow-up to the people who did not open it. Affiliate offers often need several touches before someone buys, and email is where those touches happen.
So the platform you choose matters less than the fact that you start collecting addresses now. Still, a poor first choice costs you time in migrations and, in the worst case, damages your sender reputation. Choosing well takes about an hour.
What Actually Matters at This Stage: Price, Automation, and Deliverability (In That Order)
A platform with 400 features is wasted on a list of 50 people. Three things count right now.
1. Price. When you have no sales yet, a monthly bill is a real cost. You want a free plan you can actually use: one that lets you build a signup form, send broadcasts, and ideally run a basic automation. Some free plans technically exist but lock away the one thing you need, so read the plan details before you sign up.
2. Automation you can finish in a weekend. The most valuable thing a beginner can build is a welcome sequence: a short series of emails that goes out automatically when someone joins. If the automation builder is so complicated that you give up halfway, the platform has failed you, however powerful it is.
3. Deliverability. This ranks third only because beginners can’t evaluate it by comparing feature lists. It matters enormously, though. An email that lands in spam earns nothing, and a damaged sender reputation is hard to repair. Most deliverability problems come from how you use the platform, so we will spend a full section on it below.
The order is a guide for choosing a platform, not a ranking of what hurts most when it goes wrong. Price gets you started, automation gets you earning, and deliverability decides whether any of it works.
The Free and Near-Free Platforms Worth Starting With
Plans, limits and prices change often, and any number printed in an article can be out of date by the time you read it. Treat the notes below as a description of what each platform is built for, and check its pricing page for current limits before you commit.
MailerLite
MailerLite is a common first choice for beginners because the interface is clean and the free plan has included the core tools: forms, landing pages, and automations. If you want something you can learn in an evening, it is a strong candidate.
Brevo
Brevo (formerly Sendinblue) has offered a free plan that is usually limited by how many emails you can send per day rather than by the number of contacts. That suits a small list that you email occasionally. It also includes features beyond email, such as SMS and CRM tools, which you can ignore at first.
Kit (formerly ConvertKit)
Kit is built around creators, bloggers and people who sell through content. Its forms, tagging and sequences are designed for the “someone subscribes, then receives a series of emails” pattern that affiliate marketers use. It has offered a free plan, and its tagging system makes it easy to separate subscribers by interest later.
Mailchimp
Mailchimp is the name most beginners already know. It has a free plan, though its limits have changed more than once over the years, so check what is included before you build around it. It is widely used, and plenty of tutorials exist for it.
Beehiiv
Beehiiv is built for newsletters. If your plan is to publish a regular newsletter that grows through recommendations, it deserves a look. If your plan is a short automated welcome sequence that leads to an affiliate offer, one of the platforms above fits that job more directly.
Check the affiliate link policy first
This step is easy to skip and expensive to skip. Email platforms have acceptable use policies, and some are stricter than others about affiliate content, especially when the offer is in a sensitive category. Before you pick a platform, read its policy on affiliate links and promotional content. A platform that suspends your account after you have built a list is a far bigger problem than a missing feature.
When You Need Real Automation and Which Platforms Deliver It Without a Steep Learning Curve
At some point, sending one broadcast at a time stops being enough. That point comes when you have a reason to send different emails to different people, or a sequence that should run itself while you work on something else.
Here is what “real automation” means for a beginner in practice:
- A welcome sequence. Three to five emails sent over about a week after someone subscribes. The first delivers whatever you promised on the signup form, the later ones introduce you and your recommendations.
- Tagging by interest. When a subscriber clicks a link about one topic, the platform adds a tag. Later you can send relevant emails to that group.
- Click-triggered follow-ups. If someone clicks an affiliate link in an email but you have not seen anything further, a follow-up with more detail can go out automatically.
- Removing people from a sequence. When someone has finished a sequence or taken the action you wanted, they should stop getting emails about it.
Among the platforms above, Kit and MailerLite both offer visual automation builders that a beginner can follow, where you see the sequence as a flow from trigger to emails. Brevo’s automation tools are capable too, though they sit inside a larger set of features and can feel busier.
ActiveCampaign is often named as the next step up, with deeper automation and segmentation. It is worth considering once your list and your offers justify the cost and the learning time. At 50 subscribers it is more than you need.
A note on customer tracking: if you start to want a full record of each contact’s history, a CRM can help. We covered that in our guide to the best CRM software for small business, but you can wait on it until your list is bigger.
A weekend setup plan
On Saturday, create your account, build a signup form, and write your welcome emails. On Sunday, set up the automation, send test emails to yourself, and click every link. Keep the sequence short. Four good emails you actually launch beat ten you never finish.
The Deliverability Trap That Kills Beginner Email Lists Before They Start
Deliverability is the share of your emails that reach an inbox rather than a spam folder. Platforms differ here, but beginner mistakes cause most of the damage, and almost all of them are avoidable.
Do not email people who did not ask for it. Buying a list, scraping addresses, or adding friends without permission leads to spam complaints. Mailbox providers watch complaint rates closely, and in 2024 Gmail and Yahoo tightened their requirements for bulk senders, including easy unsubscribing and low spam complaint rates. Even a small list suffers when a handful of recipients hit the spam button.
Use a double opt-in. A confirmation email checks that the address is real and that the person wants your messages. You get fewer subscribers, but they are better ones, and typos and fake addresses stay off your list.
Set up domain authentication. Platforms will walk you through connecting your own domain, usually by adding records called SPF and DKIM to your domain settings. It sounds technical, but the platform gives you the exact values to paste in. Sending from a branded domain address rather than a free webmail address improves how mailbox providers treat you.
Be consistent. Going silent for three months and then sending a large blast to everyone looks suspicious to mailbox providers and surprises your subscribers. A steady rhythm, even weekly, keeps your reputation healthier and keeps people remembering who you are.
Keep every email honest and clean. Use a subject line that matches the content, include the unsubscribe link and the physical address your platform adds to the footer (those are legal requirements in many places, including the US), and disclose that you earn commissions when you recommend something. Avoid stuffing an email with links; one clear call to action per email works better and looks less like spam.
Let unengaged people go. If a subscriber has not opened anything in a long time, stop mailing them or send a final “do you still want these?” message. A smaller list of people who open your emails protects your reputation better than a large list of people who ignore them.
None of these steps costs money, and all of them take less than an hour to put in place.
Side by Side: Which Platform Wins at Each Stage of Growth
No single platform is best for everyone, because the right tool changes as your list grows. This table matches the stage you are in to what you need and which platforms fit. Confirm current limits on each pricing page.
Stage What you need Platforms to look at first Just starting (0 to about 100 subscribers) A usable free plan, a signup form, a simple welcome sequence MailerLite, Kit, Brevo Building the funnel (100 to a few hundred) Tagging, multi-step sequences, click tracking Kit, MailerLite Newsletter-first Regular publishing and audience growth tools Beehiiv, Kit Growing offers and segments Deeper automation, conditional logic, reporting ActiveCampaign, Kit Already on a familiar tool Familiar interface, many tutorials Mailchimp
If you want one recommendation for the typical reader of this article, someone with a small list who wants to promote affiliate offers through a short automated sequence, start with Kit or MailerLite. Both are designed for exactly that pattern and are easy to learn. Choose between them by trying each one’s signup form builder and automation screen for ten minutes. Whichever one makes sense to you faster is the right one.
The main exception is a plan to run a newsletter first, with affiliate links as a side element. In that case Beehiiv deserves a closer look.
Also consider what you will promote. If you are still choosing offers, our list of high ticket affiliate programs for beginners gives you options that reward the patient follow-up that email makes possible.
How to Pick One Today and Send Your First Email This Week
You can finish this in about a week. Here is the plan.
- Pick two candidates from the table. Do not research more than two. More options just delay the decision.
- Read each pricing page and acceptable use policy. Check the free plan limits and what the policy says about affiliate links.
- Create a free account on the one that looks easier. If it does not feel right after an hour, switch to the other. Switching costs almost nothing with a tiny list.
- Build one signup form with one clear promise. Say what the subscriber will receive and how often. Something specific, like a checklist, a short guide or a weekly tip, converts better than “join my newsletter”.
- Connect your domain and turn on double opt-in. This is your deliverability foundation.
- Write a four-email welcome sequence. Email one delivers what you promised. Email two tells subscribers who you are and what your site covers. Email three teaches something useful. Email four recommends one affiliate offer, with a clear disclosure.
- Send a test to yourself and click everything. Check that links work and that the email looks right on your phone.
- Send your first broadcast. Even to 50 people, send it. Sending is how you learn what your subscribers open and click.
The platform is a tool, and the money comes from what you build with it: a signup form that attracts the right people, a sequence that earns trust, and offers that fit. A list of 50 engaged subscribers with a well-built sequence is a better foundation than a list of 5,000 who never open anything.
