How to Send Your First Email Newsletter with MailerLite (Even If You've Never Done It Before)

Go to mailerlite.com and click the green 'Get started for free' button in the top right corner. Enter your name, email address, and a password, then click 'Create my account'. MailerLite will send a confirmation email — open it and click the verification link to activate your account. Once you're in, MailerLite asks you a few onboarding questions: your company name, website URL, and what you plan to use it for. Fill these in honestly — they help MailerLite set up your account correctly and also trigger their account approval process. Important: MailerLite manually reviews new accounts before you can send campaigns. This usually takes a few hours to one business day. You'll receive an approval email when you're cleared. While you wait, you can start building your subscriber list and designing your first email. The free plan in 2026 supports up to 1,000 subscribers and 12,000 emails per month. Paid plans start at $9/month for up to 500 subscribers with unlimited emails, but the free plan is more than enough to get started.

Before you can send a newsletter, you need at least one person to send it to. In your MailerLite dashboard, click 'Subscribers' in the left-hand menu, then click the orange 'Add subscribers' button in the top right. You have three options: add subscribers one by one, import a CSV file, or copy and paste a list. For your very first newsletter, click 'Add a single subscriber' and enter your own email address — this lets you send a test later. To add a group of contacts, click 'Import subscribers' and upload a CSV file. Your CSV needs at minimum a column labeled 'email'. You can also include columns for 'name', 'last_name', and any custom fields. MailerLite will map the columns for you during the import wizard. Once imported, organize your subscribers into Groups (like 'New Customers' or 'Blog Readers') by clicking 'Groups' in the left sidebar and creating a new group. Assigning subscribers to groups makes it easy to send targeted emails later. Make sure every subscriber on your list has explicitly opted in to receive emails from you — importing random contacts violates MailerLite's terms of service and anti-spam laws like GDPR and CAN-SPAM.

Your sender details tell subscribers who the email is coming from. In MailerLite, click your profile icon in the bottom-left corner, then go to 'Account Settings', then 'Email domains and authentication'. Here you'll add and verify your sending email address. Click 'Add email domain' and enter your domain (e.g., yourbusiness.com). MailerLite will give you DNS records — specifically SPF, DKIM, and DMARC records — that you need to add to your domain's DNS settings. Log in to wherever your domain is registered (GoDaddy, Namecheap, Cloudflare, etc.) and add these records. This process takes 10–30 minutes and ensures your emails don't end up in the spam folder. Once the records are verified (MailerLite shows a green checkmark), your sending domain is authenticated. If you're using a free Gmail address for now, you can skip domain authentication temporarily, but expect lower deliverability. Also set your 'From name' — this is what subscribers see as the sender. Use your brand name or your first name plus brand name (e.g., 'Sarah from BakeCo') to feel personal and recognizable.

Now the fun part — creating your actual newsletter. From your MailerLite dashboard, click 'Campaigns' in the left menu, then click the orange 'Create campaign' button. Select 'Regular campaign' (the other options like A/B test and RSS campaigns are for later). On the campaign setup screen, fill in four fields: Campaign name (internal reference only, like 'Welcome Newsletter - January 2026'), Email subject line (what subscribers see in their inbox — make it specific and compelling, e.g., 'Welcome! Here's what to expect from us'), Preview text (the short sentence that appears after the subject line in most email apps — use this to reinforce your subject line), and From name and email (auto-filled from your sender settings). For your subject line, aim for 40–50 characters so it doesn't get cut off on mobile. Avoid all-caps and excessive exclamation points — spam filters penalize these. A good first newsletter subject line is something like 'Welcome to [Your Brand] — here's what's coming' or 'You're in! Here's your first update from us'.

After setting up the campaign details, click 'Next: Content' and then choose 'Drag & Drop Editor' — this is the easiest option for beginners. MailerLite will show you a library of pre-made templates organized by category (newsletter, promotional, welcome, etc.). For your first newsletter, click on the 'Newsletter' category and pick a simple template with a header, body text, and footer. Click 'Use this template' to open the editor. The editor works by clicking on any block to edit it. Click the header image block to upload your logo or a banner image. Click the text blocks to type your content directly. To add new sections, drag blocks from the left panel (image, button, divider, social icons, etc.) into your email. Keep your first newsletter simple: a header with your logo, a short welcome message (3–5 sentences), one main piece of content or offer, and a clear call-to-action button. The button is crucial — every newsletter should have one clear action you want the reader to take (visit your website, read a blog post, shop a product). Make sure your footer includes your physical mailing address (required by law) and an unsubscribe link (MailerLite adds this automatically).

Before sending to your subscribers, always send a test email to yourself. In the MailerLite editor, click the eye/preview icon at the top and look for the 'Send test email' button. Enter your personal email address and click send. Check your inbox within a couple of minutes. When reviewing your test email, check these things: Does the subject line and preview text look correct? Does your name and sending address appear as expected? Do all images load properly? Do all links work when you click them — especially your call-to-action button? Does it look good on both desktop and mobile (check on your phone too)? Is your unsubscribe link visible in the footer? If anything looks off, go back into the editor and fix it, then send another test. Never skip this step — typos in a live campaign go out to every subscriber and can't be recalled. If your test email lands in your spam folder rather than your inbox, double-check that your domain authentication records from Step 3 are fully verified.

After your test looks perfect, click 'Next: Recipients' in MailerLite. Here you select who receives the campaign. Choose 'Groups' and select the subscriber group you created in Step 2. If you have all subscribers in one place without groups, you can select 'All active subscribers'. MailerLite will show you a count of how many subscribers will receive the email — double-check this number looks right. Next, click 'Next: Review & Schedule'. This final screen shows you a complete summary of your campaign: subject line, sender name, recipient count, and a preview. Review everything one last time. You now have two options: 'Send now' — sends the campaign immediately to all selected subscribers, or 'Schedule for later' — lets you pick a specific date and time to send. For a first newsletter, 'Send now' is fine. Best sending times in 2026 research suggests Tuesday through Thursday, between 9am–11am or 1pm–3pm in your subscribers' time zones tend to get the highest open rates, but don't overthink it for your first send. Click 'Send now' and confirm. Congratulations — your first newsletter is live.

After sending, wait 24–48 hours and then review your campaign performance. In MailerLite, click 'Campaigns' in the left menu and find your sent campaign. Click 'Stats' or the campaign name to see the full report. The key metrics to understand as a beginner are: Open rate — the percentage of subscribers who opened your email. Industry average in 2026 is around 35–45% for small lists. A good open rate for a first newsletter is anything above 25%. Click rate — the percentage of subscribers who clicked a link in your email. Average is around 2–5%. Click-to-open rate (CTOR) — of the people who opened, how many clicked. Unsubscribes — people who opted out. A small number (under 0.5%) is normal. Bounces — emails that couldn't be delivered. Hard bounces mean invalid email addresses — MailerLite automatically removes these. Don't be discouraged by the numbers on your first send. Use them as a baseline and compare future campaigns against this one. The most important thing is that you sent it — most beginners never get past the planning stage.
