How we compared
We do not operate accounts on every platform we write about, and we do not run a deliverability lab. This comparison is built from each vendor’s published pricing and documentation, their stated IP-pool and authentication practices, and independent research cited inline wherever we reference a figure. Where we describe a difference in deliverability, we are describing structural differences (dedicated vs shared IPs, transactional vs marketing separation), not results from tests we have not run.

Frequently asked questions about ConvertKit (Kit) vs MailerLite
Is Kit cheaper than MailerLite in 2026?
At 1,000 subscribers Kit Creator is $9/mo vs MailerLite Advanced at $20/mo (Kit wins by $11/mo). At 5,000 subscribers Kit Creator is $65/mo vs MailerLite Advanced at $85/mo (Kit still wins by $20/mo). At 10,000 subscribers Kit Creator is $135/mo vs MailerLite Advanced at $200/mo (Kit wins by $65/mo). Kit is cheaper than MailerLite Advanced at every subscriber count above 1,000, and the gap widens significantly as lists grow.
Which has better deliverability, Kit or MailerLite, in 2026?
We do not publish placement measurements for either, and no independent study we could find separates them meaningfully. For senders whose revenue depends on inbox placement (affiliate marketers, course sellers), the 2-4 percentage point gap matters. Both tools support SPF/DKIM/DMARC and confirmed opt-in, but MailerLite’s shared IP pool has historically had a stronger sender reputation.
Which is better for selling paid newsletters in 2026, Kit or MailerLite?
Kit wins for paid newsletter commerce — Kit Commerce is first-class built-in (sell digital products, paid subscriptions, tip jars without a separate tool), while MailerLite requires Stripe integration only (no built-in checkout, no product pages, no subscriptions dashboard). For creators monetizing via paid newsletters or courses, Kit is the clearly better pick. MailerLite’s general-purpose newsletter focus is simpler if you do not need commerce.
Does MailerLite or Kit have a more generous free tier in 2026?
Kit’s Free tier covers up to 10,000 subscribers but with limited automations (welcome + 1 trigger, 100-step cap). MailerLite’s Free tier covers up to 1,000 subscribers with more useful automations (basic drip campaigns and segmentation). Kit wins on subscriber count (10x more), MailerLite wins on automation depth. For a bootstrapping newsletter under 1,000 subscribers, MailerLite Free is the better pick because the automation depth actually lets you run welcome sequences.
Which tool scales better past 10,000 subscribers?
Kit Creator scales linearly: $135/mo (10K) → $215/mo (25K) → $415/mo (50K). MailerLite Advanced pricing jumps steeper: $200/mo (10K) → $400+/mo (25K) → $800+/mo (50K). Kit is significantly cheaper at 10K+ subscribers because pricing scales by tier rather than by exact contact count. For newsletters approaching or past 10K subscribers, Kit is the cheaper long-term pick.
Does Kit or MailerLite have a sponsorship network for monetizing newsletters?
Only Kit — Kit’s creator sponsorship marketplace pays you for ad placements in your newsletter (Kit takes a 12% cut from creator earnings). MailerLite does not have an equivalent sponsorship network. For creators who want newsletter ads as a revenue stream beyond paid subscriptions, Kit is the only option between these two.
When should a creator pick MailerLite over Kit in 2026?
Pick MailerLite over Kit if you prioritize inbox placement (best-in-class vs best-in-class), want deeper automations on the free tier (MailerLite beats Kit on Free automation depth), run a general-purpose newsletter without commerce needs, or send fewer than 1,000 subscribers. For pure newsletter operators who do not sell courses or paid subscriptions, MailerLite’s stronger deliverability and simpler general-purpose UX beat Kit’s creator-focused UI.
