For most independent creators, bloggers, and solopreneurs building a list from scratch, Kit wins. Its free plan covers up to 10,000 subscribers with no credit card required, and its visual automation builder is built for creator funnels. But if budget is your top constraint, Brevo’s send-volume pricing makes it uniquely affordable at scale. If you need an all-in-one marketing platform with landing pages, social ads, and retargeting built in, Mailchimp still has the widest feature set, though its free plan has shrunk significantly. None of this is obvious until you really map out your actual costs at each subscriber tier, which we’ve done below.

Kit (ConvertKit) deep dive
Kit was built by creators for creators. If you’re a blogger, YouTuber, podcaster, or course creator, every design decision in Kit’s interface reflects your workflow, not an enterprise marketing team’s.
As of July 2026, Kit’s free Newsletter plan supports up to 10,000 subscribers with unlimited email broadcasts, unlimited landing pages, and unlimited forms, the most generous free tier of any major email marketing platform. The tradeoff: the free plan only includes one basic automation. Visual automation sequences are locked behind the Creator plan.
The Creator plan, starting at $39/month for 1,000 subscribers ($33/month billed annually), unlocks what Kit is known for: a drag-and-drop visual automation builder that lets you create complex, behavior-triggered sequences without touching code. Tag-based segmentation means a single subscriber can belong to multiple segments without you paying for them twice. Unlike Mailchimp’s list-based model, cross-list contacts don’t inflate your bill. This alone saves real money as your list grows.
“Kit’s visual automation builder uses tag-based segmentation rather than list-based billing, meaning a subscriber who belongs to three segments still counts as one contact. Mailchimp’s list-based model can charge for the same contact across multiple audiences.”
A unique feature Kit offers is the Creator Network, a built-in recommendation engine that lets other Kit creators promote your newsletter to their audiences. No other platform on this list has an equivalent. If you’re building a newsletter audience, this is genuinely useful, not just a checkbox feature.
The catch: Kit’s September 2025 price hike pushed Creator from $15/month to $39/month at 1,000 subscribers, a 160% increase. At scale, Kit is expensive, 10,000 subscribers on Creator costs approximately $139/month. A lot of longtime users felt burned by that jump, and it’s worth factoring into whether you trust Kit’s pricing long-term.
Pros & Cons:
| Pros | Cons |
|---|---|
| Most generous free plan (10K subs) | Expensive at scale (10K subs = ~$139/mo) |
| Visual automation builder is best in class for creators | Email templates are limited and text-focused |
| Built-in digital product sales (courses, ebooks) | No SMS or multi-channel marketing |
| Creator Network for organic list growth | September 2025 price hike soured many users |
| Tag-based segmentation = no double-charging | Advanced reporting only on Pro plan ($79/mo+) |
Mailchimp deep dive
Mailchimp is the 800-pound gorilla of email marketing. Its brand recognition and integration ecosystem (300+ integrations) are hard to beat.
As of July 2026, Mailchimp’s free plan supports 500 contacts and 1,000 email sends per month, with a 500-send daily cap. For solopreneurs building a list, 500 contacts is a tight ceiling that forces a paid upgrade much sooner than Kit or Brevo.
“Mailchimp’s free plan caps at 500 contacts with a 500-email daily limit. For a creator adding 100 subscribers per month, that ceiling hits in 5 months. Kit’s 10,000-subscriber free cap, by contrast, would take over 8 years to hit at the same growth rate.”
Where Mailchimp still delivers: its 100+ professionally designed email templates, its content optimizer with AI-powered subject line suggestions, and its Facebook/Instagram ad integration. Templates are genuinely the best in this comparison, if you care about polished design.
Pros & Cons:
| Pros | Cons |
|---|---|
| 100+ professional email templates | Free plan significantly reduced (500 contacts) |
| All-in-one: email + social ads + landing pages | Pricing escalates steeply at scale |
| 300+ integrations, best ecosystem | Automation builder less intuitive than Kit’s |
| Content optimizer with AI subject line suggestions | Per-contact billing punishes list growth |
Brevo deep dive
Brevo (formerly Sendinblue) made a clever architectural choice: pricing is based on emails sent, not contacts stored. This single decision changes the cost math completely.
As of July 2026, Brevo’s free plan offers unlimited contact storage with 300 emails per day, enough for a weekly newsletter to 2,000 subscribers at zero cost. The Starter plan at $9/month raises the ceiling to 5,000 emails per month with no daily cap.
“Brevo charges $9/month for 5,000 emails sent to unlimited contacts, while Kit charges $39/month for 1,000 subscribers and Mailchimp charges $20/month for 500 contacts. For a creator with a 2,500-person list sending twice a month, Brevo is 77% cheaper than Kit on a per-month basis.”
Brevo excels at multi-channel: email, SMS, WhatsApp, live chat, and transactional email all run from one dashboard. This is genuinely useful if you want to coordinate channels without juggling separate tools.
Pros & Cons:
| Pros | Cons |
|---|---|
| Send-volume pricing = cheapest at scale | Limited email templates (40+) vs Mailchimp (100+) |
| Unlimited contacts on all plans | No digital product sales or creator-specific features |
| Free plan: 300 emails/day, unlimited contacts | Automation builder less polished than Kit’s |
| Multi-channel: email + SMS + WhatsApp + chat | Shared IP pool can affect deliverability |
Side-by-side: pricing breakdown at every tier
| Subscribers | Kit (Creator) | Mailchimp (Standard) | Brevo (Starter, 2 sends/mo) |
|---|---|---|---|
| 500 contacts | $39 (free plan handles this) | $20 | $9 |
| 2,500 contacts | $59 | $50 | $9 |
| 10,000 contacts | $139 | $100 | $18 |
| 25,000 contacts | $199 | $210 | $39 |
Brevo pricing assumes 2 emails per subscriber per month. More frequent sends increase cost.
When to choose each
- Choose Kit if: you’re a content creator, blogger, course seller, or newsletter writer who needs visual automations and wants to sell digital products directly from your email platform. The free plan is generous enough that you can grow into a real audience before paying anything, which is rare in this space.
- Choose Mailchimp if: you run a small business that needs email plus social ads, landing pages, and retargeting in one platform. The templates and multi-channel features still make it the most complete package, even if the free tier is disappointing.
- Choose Brevo if: budget is your top priority, you anticipate rapid list growth, or you need multi-channel marketing (email + SMS + WhatsApp). The per-email pricing sounds boring, but it saves serious money at scale.
FAQ
Is Kit’s free plan really for 10,000 subscribers?
Yes. As of July 2026, Kit’s free Newsletter plan allows up to 10,000 subscribers with unlimited email broadcasts, landing pages, and forms. The limitation: it includes only one basic automation. Mailchimp’s free plan caps at 500 contacts, Brevo limits to 300 emails/day.
Did Mailchimp reduce its free plan recently?
Yes, significantly. Mailchimp’s free plan was cut to 500 contacts and 1,000 monthly email sends. For creators who remember Mailchimp’s earlier generous free tiers, Kit or Brevo feel dramatically more welcoming.
Which platform has the best affiliate commission?
Kit, by a wide margin. Kit’s official affiliate program (via Impact) pays 30% recurring lifetime commission. Mailchimp offers a $30 bill credit per referral. Brevo offers $50 credit per referral. If earning affiliate income from your recommendation matters, Kit is in a different league.
Which platform has the best deliverability?
Independent tests consistently show Kit leading on inbox placement rates (91–99.8%), followed by Brevo (around 88%) and Mailchimp (around 86%). Kit’s text-heavy emails tend to trigger fewer spam filters, which partially explains the gap.
