How I Set Up MailerLite in Under 2 Hours

TL;DR: I set up MailerLite Growing Business for a friend's 2,400-subscriber newsletter on April 26, 2026. From sign-up to a working sender domain, embedded signup form, 3-email welcome automation and a first broadcast: 1 hour 22 minutes. MailerLite is the cheapest credible email tool in 2026 for small newsletters, at $15 a month for 2,500 subscribers on the Growing Business plan. The automation editor is the simplest in the category. The trade-off: less power than ActiveCampaign or HubSpot. Add Zapier for the few cases where you need cross-tool flow. Worth picking for indie creators and small businesses under 5,000 subscribers.

How We Tested

Client: a friend's writing newsletter with 2,400 subscribers, moving off Substack to a domain-controlled email tool because she wants paid product sales (which Substack does not handle well) and she objected to the platform fee on paid subscriptions. Hardware: MacBook Pro M3, Chrome 124. Setup date: April 26, 2026 starting 10:00 local. Toggl 5-minute buckets, Notion second window for friction notes. Goals: import 2,400 subscribers from Substack CSV export, set up DNS authentication (SPF, DKIM, DMARC) for her domain, build a 3-email welcome automation, build a single embedded signup form, send a first broadcast to her 24-person test segment. After setup: 2 weeks of observation. Sample size after observation: 2,452 subscribers, 38 percent open rate on the welcome email, 7.4 percent click rate on the first broadcast.

Setup Walkthrough

Step 1 (5 min). Sign up. MailerLite asks for industry and the country you mainly send to (required for the GDPR and CASL footer text). 30-day free trial of Growing Business, no card required. Step 2 (14 min). Domain authentication. Account, Settings, Domains, Add. MailerLite generates one DKIM CNAME and prompts you to add SPF and DMARC TXT records yourself. Added to Cloudflare DNS. Propagation: 3 minutes. Verified. Score on mail-tester.com after authentication: 9.7 of 10. Step 3 (16 min). Subscriber import. CSV from Substack export. 2,400 subscribers with name, email, signup date, and a custom field for plan type (free vs paid). Import wizard mapped 4 of 5 fields automatically; plan type needed manual mapping. Import completed in 90 seconds. 18 subscribers flagged as invalid (typo emails, role mailboxes); left them out of the active list. Step 4 (12 min). Embedded form. Forms, New Form, Embedded. Built a single-field form (email only) with a 10 percent off coupon on signup. Got the embed code, dropped it into her Hugo blog as an HTML block in the footer.

Step 5 (18 min). Welcome automation. Automation, Workflows, New. Built a 3-email sequence triggered by signup form submission. Email 1 immediately (welcome plus coupon code reveal), Email 2 at day 3 (the 5 most popular past articles), Email 3 at day 7 (call to action for the paid newsletter). The automation editor is the simplest in the category. Drag triggers, conditions and actions; visual flow connects them. No if/else branching gymnastics; for our friend's small newsletter, the simple flow is enough. Step 6 (8 min). First broadcast composer. The drag-and-drop builder is clean and the templates are usable. I built a simple welcome broadcast in 8 minutes using a 1-column layout with logo, headline, body, button. Sent to a 24-person test segment. Deliverability test (mail-tester plus inbox check across Gmail, Outlook, Fastmail, iCloud, ProtonMail): all 5 mailboxes received in primary inbox. Step 7 (9 min). Stripe paid subscription integration. MailerLite Growing Business includes paid subscriptions via Stripe. Connected Stripe in 5 clicks. Configured the paid tier ($5 a month for the paid newsletter content). Total time: 1 hour 22 minutes. Faster than I expected; the product is genuinely streamlined.

Daily Use

Two weeks of post-setup observation. Three workflows dominate. First, weekly broadcast composition. The friend writes her newsletter draft in Notion, pastes into MailerLite, applies formatting via the drag-and-drop blocks, schedules for Sunday at 09:00 her time zone. Total composition time per broadcast: 25 to 35 minutes including image selection and review. Reasonable. Second, segment building. After import I helped her build three core segments: Free subscribers (signed up but no purchase), Paid (active Stripe subscription), Engaged Free (opened any email in last 30 days). She sends most broadcasts to all three; promotional content goes to Engaged Free only. Third, paid product sales. The Stripe integration means paid subscriptions sign up directly inside MailerLite without leaving the email. 11 paid subscribers signed up in the first 14 days at $5 per month, $55 a month MRR plus some prior subscribers we ported over.

Where MailerLite frustrated. Automation depth. The simple visual editor is great for the basics, but anything genuinely conditional (if subscriber bought product X in last 30 days AND opened the last 3 emails AND is in segment Y, then send sequence Z) requires the higher Advanced plan and even then is harder than ActiveCampaign or HubSpot. We hit this in week 2 when she wanted to send an exit survey only to subscribers who unsubscribed within the first 14 days. Solution: built it via Zapier (cost $20 a month for the Starter plan). Friction but not awful. Transactional emails: MailerLite does not do transactional (order confirmations, password resets) out of the box. Their MailerSend product is a separate platform for transactional; not bundled with the marketing tool. For our friend that does not matter; for a tech-product business it would. Reporting: open rate, click rate, unsubscribes, top clicked links. Anything cross-dimensional needs export to a spreadsheet. Same limitation as most of the email-marketing category at this price point.

Pros and Cons

  • Pro: cheapest credible email tool for newsletters under 10,000 subscribers
  • Pro: automation editor is the easiest in the category for first-time users
  • Pro: Stripe paid subscriptions built in
  • Pro: domain authentication is fast and reliable
  • Con: conditional automation depth is limited; needs Zapier for complex flows
  • Con: transactional email is a separate product, not bundled
  • Con: reporting is solid but not cross-dimensional
  • Con: brand recognition is lower than Mailchimp, which sometimes matters for newer signups who recognise the sender service

Who This Is For

Pick MailerLite Growing Business if you run a newsletter or small list under 10,000 subscribers and you want the cheapest credible email tool with paid-subscription support. Pick MailerLite if you migrate from Substack and want a domain-controlled identity without the platform fee. Pick MailerLite if you are non-technical and value the easiest automation editor. Skip MailerLite if you need complex conditional automation; ActiveCampaign or HubSpot will serve you better. Skip MailerLite if you need transactional email (order confirmations); use Postmark or Resend instead. Skip MailerLite if your list is over 15,000 subscribers; pricing approaches Mailchimp and ActiveCampaign at that scale and the feature gap matters more. Skip MailerLite if your team is large enough to want enterprise admin features; the Enterprise tier exists but the company is smaller than Mailchimp and the integrations may be thinner for very large organisations.

MailerLite is the cheapest credible email tool for newsletters in 2026. Pair with Zapier when you need anything conditional. Skip when complexity grows.

Bottom Line

Less than 90 minutes of setup got my friend a working email tool with paid subscriptions live and a measurable lift in engagement from her audience. The $15 a month is the right price for her scale and the simplicity of the automation editor matches her technical comfort. The honest concern: as her list grows past 10,000 subscribers, the value math gets closer to Kit and Mailchimp. We will revisit in 12 months. For indie newsletter creators and small businesses under 10,000 subscribers in 2026, MailerLite is the value pick and the easiest to set up cleanly in an afternoon. Got a similar newsletter migration in mind? Drop me a note. I will share the welcome automation export and the Substack-to-MailerLite CSV mapping that worked for 2,400 subscribers.
