If you’re running a content business with fewer than 5,000 subscribers, you’re in the sweet spot where platform choice actually matters. Pick wrong and you’ll either overpay for features you don’t use or outgrow your tool in six months.
ConvertKit and MailerLite both target solo operators and small teams, but they solve different problems. Here’s what each does well, where each falls short, and who should pick which.
Pricing: where the gap widens
MailerLite’s free tier covers up to 1,000 subscribers and includes automation, landing pages, and a website builder. You’ll pay $9/month for 1,000–2,500 subscribers, $18/month for 2,500–5,000.
ConvertKit starts at $25/month for up to 1,000 subscribers. At 2,500 subscribers you’re paying $41/month; at 5,000 it’s $66/month. There’s a free tier capped at 300 subscribers, but it strips out automation—the main reason to use ConvertKit in the first place.
If budget is tight and you’re just starting, MailerLite saves you $300–$600/year at the same list size. ConvertKit’s pricing assumes you’re monetising early or plan to.
Automation: depth vs. simplicity
ConvertKit’s visual automation builder lets you branch, tag, delay, and score subscribers based on link clicks, form submissions, product purchases, and custom events. You can build sequences that feel like decision trees. It’s overkill if you’re just sending a weekly digest, but essential if you’re running a paid community, a course funnel, or segmented content tracks.
MailerLite’s automation is lighter. You get triggers, delays, conditions, and basic branching. It handles welcome sequences, re-engagement flows, and simple product funnels without friction. But once you need multi-step logic—like “if they clicked this link but didn’t buy, tag them and send a different sequence”—you’ll hit the ceiling fast.
Non-obvious tip: MailerLite’s workflow editor saves every change instantly. ConvertKit requires you to manually activate automations after editing. That’s a feature, not a bug—it prevents you from accidentally breaking a live sequence. But it also means you need to remember to turn things back on.
Forms, landing pages, and creator-focused extras
Both platforms include landing pages and signup forms. MailerLite’s templates look cleaner out of the box and load faster. ConvertKit’s forms integrate tightly with its tagging system, so you can pre-segment subscribers at signup without Zapier.
ConvertKit also includes a commerce layer—you can sell digital products, subscriptions, and tip jars directly through the platform. It takes a 3.5% + $0.30 transaction fee on top of Stripe’s cut, but it’s built in. MailerLite doesn’t offer native e-commerce; you’ll need to connect Gumroad, Stripe Checkout, or a course platform.
If you’re monetising through paid newsletters or digital products, ConvertKit’s commerce tools save you from duct-taping three services together. If you’re running ads, affiliates, or sponsorships, MailerLite’s lower base cost matters more.
Deliverability and reporting
Both platforms maintain strong sender reputations and handle SPF/DKIM setup for you. Deliverability differences at this scale come down to list hygiene, not platform choice.
ConvertKit’s reporting is subscriber-centric: you can see every action a single subscriber took across broadcasts, automations, and landing pages. MailerLite’s reporting is campaign-centric: opens, clicks, unsubscribes per send. ConvertKit’s view is better for understanding individual journeys; MailerLite’s is faster for diagnosing a bad campaign.
Who should pick which
Choose MailerLite if you’re pre-revenue, sending one or two emails per week, and need to keep costs under $20/month. It’s also the better pick if you value design flexibility and don’t need multi-step conditional logic.
Choose ConvertKit if you’re already monetising, running segmented content tracks, or plan to sell directly through email. The automation depth and commerce tools justify the higher price once you’re past the “is this working?” phase.
For most operators under 5,000 subscribers, the decision comes down to one question: are you optimising for cost or for automation depth? MailerLite wins the first; ConvertKit wins the second. Neither is a bad choice—just different bets on where your business is headed.
