solobuildWhat Kit actually is
Kit, which you may know by its former name ConvertKit, is an email marketing platform built specifically for creators and solopreneurs. It rebranded to Kit in 2024, but the focus has stayed the same. This is a tool for people who grow an audience and stay in touch with them, whether that is a newsletter, a course launch, or simple updates to a list of subscribers. Everything about it is shaped around that job rather than around a marketing department's needs.
What makes Kit feel different from older email tools is its model. Instead of juggling separate lists, Kit uses a single subscriber base with tags and segments, so one person is one contact no matter how many things they signed up for. For a solo builder, that keeps your audience clean and your billing honest, since you are not paying for the same subscriber twice. It is a small design choice that quietly makes everything simpler.
The pricing, and the generous free plan
Kit's free plan is one of the most generous in the category, and it is a real reason to start here. You can manage up to 10,000 subscribers, send broadcasts, and build landing pages and forms without paying anything. For a solopreneur still growing an audience, that means you can run a real newsletter for a long time before a bill ever arrives.
When you do upgrade, the paid plans unlock the parts that matter for growth. The Creator plan starts around $15 a month and adds automated sequences and visual automations, while Creator Pro near $29 a month adds advanced reporting, a newsletter referral system, and more. Pricing scales with your subscriber count, which is fair, since a bigger list usually means the tool is earning its keep.
Automation and sequences
Automation is where Kit earns loyalty, because it is powerful without making you feel like a developer. You can build sequences that send a series of emails automatically when someone joins your list, which is exactly what you want for a welcome series or a course. The visual automation builder lets you map out what happens when, with branching based on what subscribers do.
For a solo builder, this is the difference between email being a chore and email running itself. You set up a welcome sequence once and every new subscriber gets it without you touching anything. The tagging system ties into this neatly, so you can send the right message to the right people based on what they have done rather than blasting everyone the same thing.
The Creator Network and growth
One feature genuinely sets Kit apart for people trying to grow. The Creator Network lets creators recommend each other's newsletters, so when someone subscribes to you, they can be shown other newsletters worth following, and you can be recommended in return. For a solopreneur starting from a small list, this built-in growth loop is something most email tools simply do not offer.
It will not replace doing the work of creating something worth subscribing to, and it should not be the only reason you choose Kit. But as a free, built-in way to gain subscribers from other creators in your space, it is a real advantage. Growth is the hardest part of running a newsletter, and Kit at least gives you a head start.
Where Kit frustrates
Kit is focused, and that focus has tradeoffs. It is built for creators and audience-building, so if you need a deep sales CRM with detailed deal pipelines and heavy e-commerce features, Kit is not trying to be that. It has added commerce tools for selling digital products, but a business centered on complex sales may find it lighter than a dedicated CRM.
The design is also opinionated. Kit's emails lean clean and text-forward, which is great for deliverability and the creator aesthetic but less suited to heavily designed, image-rich campaigns. If your brand depends on elaborate visual newsletters, you may find Kit's simplicity limiting rather than freeing. For most solo creators, though, the plain style is a feature.
Who Kit is for, and who should look elsewhere
Kit is the right tool for the solopreneur building an audience through email. A newsletter writer, a course creator, a coach, or anyone growing a list of subscribers will find that Kit fits the way they actually work. The generous free plan makes it especially easy to recommend, because you can start and grow for free before committing any money.
It is a weaker fit for a few cases. A business that needs a full sales CRM with complex pipelines may want a heavier tool, and a brand built on richly designed campaigns might prefer something more visual. If your needs are extremely basic and you only ever send the occasional update, a simpler or cheaper tool might be enough. But for audience-building, Kit is near the top of the list.
The bottom line
Kit is email marketing that understands creators, and it shows in every choice it makes. The free plan is generous, the automation is powerful without being complicated, and the Creator Network gives you a rare built-in way to grow. For a solo builder whose business runs on a newsletter or an audience, it is one of the easiest tools to recommend.
The honest caveat is to match it to your goal. If you are building an audience, Kit is excellent, and if you are running a complex sales operation, look at a dedicated CRM instead. For most solopreneurs growing a list, though, Kit does the job with a clarity that few competitors match.
