Getting Started with MailerLite: From Signup to Your First Newsletter

Who this guide is for
You are a freelancer or creator starting an email list from zero — or from a scattered pile of contacts in a spreadsheet. You do not need a course or a marketing degree; you need an account, a way for people to sign up, and one real email sent to real people. This guide walks through exactly that, in order, on MailerLite's free plan. By the end you will have a working signup form, your first contacts imported, and your first campaign out the door.
If you are still deciding whether MailerLite is the right tool at all, read the full MailerLite review first. This page assumes you have decided, or want to try it while you decide — the free plan costs nothing and covers up to 250 subscribers and 2,500 emails a month, which is enough to learn on.
Step 1: Create your account
Sign up with your email address and set up your account details — who you are and what you send emails about. Do not rush past this part. Email tools ask these questions because sender identity matters: your subscribers, and the spam filters watching over them, both want to know a real person or business is behind the account. Use your real name or your business name, the one your readers will recognise.
You start on the free plan. New accounts also get a 14-day premium trial of the paid features, which is useful for looking around — but nothing in this guide requires a paid plan, so do not feel pushed to upgrade before you have sent anything. Learn the basics on free; pay when the limits, not the trial timer, tell you to.
Step 2: Set up your signup form before anything else
A list needs a door. Before you write a single newsletter, create the signup form people will use to join. The free plan includes signup forms, one website, and one landing page — so even if you have no website of your own yet, you can put your form on the MailerLite landing page and share that link wherever your audience already is: your social profiles, your videos, your email signature.
Keep the form short. An email address and, at most, a first name. Every extra field costs you signups. Write the invitation the way you would say it out loud — what the reader gets, how often, and a plain promise that they can leave whenever they like. One honest sentence outperforms a paragraph of hype.
Step 3: Import the contacts you already have
Starting from zero rarely means starting from nobody. If clients, customers, or readers have already given you their email addresses and agreed to hear from you, you can import them — typically as a spreadsheet or CSV file — instead of waiting for the form to fill up on its own.
Two rules matter here. First, permission is not optional: only import people who actually opted in to your emails. Never buy, borrow, or scrape a list — it fills your account with spam complaints, wrecks your sender reputation, and can get the account shut down. Second, smaller and honest beats bigger and dusty. A list of 40 people who asked to hear from you will outperform 400 strangers on every measure that matters. Note that unsubscribes and bounces do not count toward your plan's subscriber limit, so there is no penalty for people leaving — let them.
Step 4: Create your first campaign
A campaign is simply one email sent to your list. For your first one, keep the job small: introduce yourself, remind people why they signed up, and give them one useful thing — a tip, a story, an answer to a question your clients keep asking. One email, one purpose. You are not launching a brand; you are starting a conversation.
Practical points that save beginners real pain:
- Write the subject line last, and keep it plain. Say what is inside. Curiosity tricks and all-caps urgency are how small senders end up in spam folders.
- Preview before you send, and send a test copy to yourself. Read it on your phone, where most of your subscribers will read it. Check that links work and the layout holds up on a small screen.
- One clear next step. Reply to me, read this post, book here — pick one. An email that asks for five things gets none of them.
Step 5: Send it — then check the right numbers
Send the campaign, and then resist judging it within the hour. Give it a day, then look at three things: how many people opened it, how many clicked, and how many unsubscribed. A handful of unsubscribes after a first send is normal — those people were never really on your list. What you are looking for across your first few sends is a pattern, not a verdict: are opens steady, do people click the one thing you asked them to click, does anyone reply?
Replies are the number nobody charts and everybody should want. A newsletter people answer is a business asset. One they silently delete is a chore. Send regularly enough that readers remember who you are — for most freelancers and creators, that means a steady weekly or fortnightly rhythm you can actually keep.
The limits to know before you settle in
The free plan is a starting point, not a home. Its 250-subscriber limit is a hard wall: pass it and sending locks until you upgrade or remove subscribers. The 2,500 emails a month is a second, quieter ceiling if you send often. The first paid step, Comfort, starts at $12 a month for up to 500 subscribers — the full tier-by-tier breakdown is in the MailerLite pricing guide. None of this is a reason to avoid starting; it is a reason to know where the walls are before you lean on them.
Who should skip this (for now)
MailerLite's free plan is the wrong starting point if your list already has well over 250 people and no budget at all — you will hit the wall on day one and spend your first week doing admin instead of sending. It is also a poor fit if your whole model is high-volume daily sending: the free plan's monthly email allowance will run out fast. And if you know you need complex, branching automation from the start, note the free plan includes up to 3 automations — enough to learn with, not enough to build a machine. Everyone else starting small is exactly who this setup is for.
The bottom line
Account, form, import, campaign, send, check. That is the whole path, and none of it needs a paid plan or a free afternoon of tutorials. Set up the form today, import the people who already trust you, and send one honest email this week. A small list that hears from you regularly is worth more than a big plan that never sends.
