5 Best ConvertKit Alternatives in 2026

Beehiiv was built by former Morning Brew operators specifically to grow and monetize newsletters, and that focus shows. Where Kit treats the newsletter as a way to promote products, Beehiiv treats the newsletter as the business. It includes a built-in referral program that SideStackers reports can grow lists 40 to 60% faster, an ad network that pays creators an estimated $200 to $500 a month, paid subscriptions and detailed growth analytics. For anyone whose audience is the asset, it is purpose-built.

It is subscriber-priced like Kit, with a free plan up to 2,500 subscribers and paid tiers from around $49 a month. That can land slightly above MailerLite at the same size, but as SideStackers notes, the referral program and ad network usually more than cover the difference for a serious newsletter. Migrating from Kit is quick, often done in one to two hours. The trade-off is that Beehiiv is built for newsletter revenue, not selling courses, so product sellers may miss Kit’s commerce tools.

Pick it if growing and earning from a newsletter is your main goal.

Skip it if your business is selling courses and digital products.

MailerLite is the closest like-for-like swap for Kit, and the headline reason to switch is price. It offers the same core toolkit, a drag-and-drop editor, landing pages, pop-ups, automation and even a website builder, at a fraction of the cost. Sequenzy puts it at around $50 a month for 10,000 subscribers against Kit’s $119 at the same size, and SideStackers measures it at roughly 56% cheaper at 5,000 subscribers. It also sells digital products, which Beehiiv does not.

The free plan covers up to 1,000 subscribers, and paid plans start from around $9 a month. MailerLite’s automation is solid rather than spectacular, so power users running complex branching sequences may find it shallower than Kit or ActiveCampaign. For the large majority of creators, though, it does almost everything Kit does for noticeably less money, which is exactly why it tops most budget-focused comparisons.

Pick it if you want Kit-like features for noticeably less money.

Skip it if you need the deepest automation on the market.

Flodesk solves the single biggest complaint about Kit: a bill that grows with your list. As Beehiiv’s own comparison puts it, Flodesk takes the opposite approach to subscriber pricing, charging one flat monthly rate, around $38, for unlimited subscribers and unlimited emails. For a creator with a large or fast-growing list, that can mean paying a fraction of what Kit would charge at scale. It is also widely regarded as producing the most beautiful newsletters in the category without any design skill.

The flat rate is the whole pitch, and the trade-offs follow from it. Flodesk’s automation is simpler than Kit’s, and its free plan does not let you send emails, functioning more as a setup tier. For design-led creators and anyone with a big list who is tired of watching the price climb, the predictability and polish are worth it. For complex automation needs, look elsewhere.

Pick it if you have a large list and want predictable, flat pricing.

Skip it if complex automation is central to your strategy.

If you are leaving Kit because its automation cannot keep up with you, ActiveCampaign is the upgrade. It is widely rated the most powerful automation platform in this group, with visual branching workflows, conditional logic, lead scoring, a built-in CRM and SMS alongside email. For a creator or small business running sophisticated funnels, behavioural triggers and sales pipelines, it does things the simpler tools on this list cannot.

That power is the catch. Pricing starts around $15 a month but rises with both contacts and feature tier, and the platform has a real learning curve. As several newsletter-platform roundups point out, it is overkill for someone who just sends a weekly email. Choose it when automation and CRM depth are the point, not when you want the simplest path from Kit.

Pick it if advanced automation and a CRM are what you actually need.

Skip it if you send a straightforward newsletter and want simplicity.

Substack takes a completely different approach to pricing: it is free to use and instead takes 10% of any paid subscription revenue you earn, on top of payment processing fees. That makes it the lowest-risk way to start a paid newsletter, since you pay nothing until you are actually earning. It also has a built-in discovery network and recommendation engine that can bring you readers, which none of the others offer at the same scale.

The trade-offs are control and ownership. Substack is more media platform than marketing tool, with limited automation, basic customization and design, and a model where you are part of their ecosystem rather than running your own. For writers focused on publishing and building a paid audience from scratch, it is ideal. For a business that wants automation, branding control and to sell products, the dedicated tools above fit better.

Pick it if you want to launch a paid newsletter with zero upfront cost.

Skip it if you want automation, branding control or product sales.
