We tested 7 platforms so you can skip the signup-and-regret cycle. Here is what each free plan delivers in 2026.
by Alkan Balkaya · Last updated: 2026-04-22Free email marketing tools have become the default starting point for growing businesses, solo founders, and side projects. The problem is that “free” varies wildly between platforms. One tool gives you 10,000 subscribers but strips out automation. Another caps you at 250 contacts and charges the moment you grow past a single campaign. Picking the wrong free plan means migrating your list, rebuilding templates, and losing momentum exactly when it matters most.

I have spent the last six years building Mailsoftly, so I have a bias you should know about upfront. But I have also tested every major free email marketing software on this list with real campaigns, real contacts, and real deliverability checks. This guide ranks each tool by what you actually get at zero cost, how painful the upgrade is when you outgrow the free tier, and whether the platform is designed to help you succeed or funnel you into a paid plan as fast as possible. If you want a broader look at how these platforms stack up beyond free tiers, our email platform comparisons page covers paid plans side by side.
Below, you will find the seven free email marketing tools worth your time in 2026, ranked by generosity, usability, and upgrade value.

Before diving into individual reviews, here is what each free email marketing tool actually delivers. All pricing data verified as of 2026-04-15.
| Platform | Contact / Subscriber Limit | Email Send Limit | Branding Removed? |
|---|---|---|---|
| Mailsoftly | 500 contacts | 2,000/month | Yes |
| Brevo | Unlimited | 300/day (~9,000/month) | No |
| Kit | 10,000 subscribers | Unlimited broadcasts | No |
| MailerLite | 250 subscribers | 2,500/month | No |
| HubSpot | N/A (CRM-based) | 2,000/month | No |
| Klaviyo | 250 profiles | 500/month | No |
| Mailchimp | 250 contacts | 500/month | No |
Mailsoftly’s free plan gives you 500 contacts and 2,000 emails per month with no platform branding on your emails. That alone sets it apart from every other tool on this list. You get access to the full drag-and-drop editor, automation workflows, audience segmentation, and deliverability monitoring at no cost. There is no feature gating that forces an upgrade before you can send a proper welcome sequence.
The real advantage surfaces when you outgrow the free tier. Mailsoftly’s Basic plan starts at $39 per month on annual billing for 5,000 contacts and 40,000 emails. Compare that to Mailchimp, where moving from 250 free contacts to 500 paid contacts already costs $13 per month on Essentials (and you still get their branding unless you upgrade further). Mailsoftly’s free-to-paid jump is the smoothest of any platform here because the interface, features, and workflows stay identical. You simply unlock a higher ceiling.
Where Mailsoftly trails larger platforms is in third-party integrations. The native integration library is growing but not yet as deep as Mailchimp or HubSpot. For most growing businesses running a website, an online store, or a landing page, the existing integrations cover the essentials. You can review full Mailsoftly pricing and plan details to see exactly what each tier includes before committing.
Brevo (formerly Sendinblue) takes a fundamentally different approach to pricing. Instead of charging per contact, it charges by email volume. The free plan lets you store unlimited contacts but limits you to 300 emails per day, which works out to roughly 9,000 emails per month. Every email on the free tier carries Brevo branding, and removing that logo costs $10.80 per month extra on paid plans.
This model is ideal if you have a large list but send infrequently. A monthly newsletter to 5,000 people fits comfortably under the 300-per-day cap if you spread sends across a few days. Where it falls apart is time-sensitive campaigns. If you need to blast a flash sale to your full list at once, the daily cap will throttle delivery and your audience will receive your urgent message across multiple days instead of one.
Brevo’s Starter plan begins at $9 per month for 5,000 emails. Scaling to 20,000 emails costs $19. These are among the lowest entry-level paid plans on the market, making Brevo a solid choice if your primary concern is keeping costs minimal as volume grows. The trade-off is that Brevo’s automation builder and template selection feel less polished than dedicated email-first platforms.
Kit (formerly ConvertKit) offers the highest subscriber count on any free plan: 10,000. That headline number sounds extraordinary until you read the fine print. The free tier limits you to a single automation, requires Kit branding on every email, and strips out advanced reporting. You can send unlimited broadcasts, which makes it viable for a straightforward newsletter. But the moment you need a multi-step welcome sequence or a segmented drip campaign, you hit the wall.
Kit was built for content creators, bloggers, and course sellers who monetize an audience through digital products. Its landing page builder and subscriber tagging system reflect that focus. If you run an e-commerce store or a B2B SaaS, the feature set will feel incomplete. There is no built-in CRM, limited reporting on revenue attribution, and the template library leans heavily toward plain-text-style emails.
Upgrading from free to Kit’s Creator plan costs $39 per month at 1,000 subscribers. At 10,000 subscribers, Creator costs $139 per month. That price jump is steep compared to platforms that start lower and scale more gradually. Kit’s free plan is best treated as a long-term newsletter host for creators who do not need automation, not as a starter tier for growing businesses.
MailerLite has quietly built one of the cleanest, most intuitive email editors in the industry. The free plan covers 250 active subscribers and 2,500 emails per month since the June 2026 update, enough for a very small list sending weekly campaigns. You get access to the drag-and-drop editor, landing pages, pop-up forms, and basic automation. The interface is fast, uncluttered, and requires almost no learning curve.
The catch is approval. MailerLite manually reviews every new account, and rejection rates are notoriously high for affiliate marketers, resellers, and accounts without a clear website. If your business is legitimate and you pass the review, the free experience is excellent. If you get rejected, there is no appeal process that moves quickly. Plan for a 24- to 72-hour wait before you can send your first email.
MailerLite’s free tier does include the platform logo on your emails. Advanced features like auto-resend to non-openers, A/B testing for automations, and the ability to sell digital products are reserved for paid plans. The upgrade path starts reasonably but climbs as your list grows, making it a solid beginner choice with a moderate long-term cost trajectory.
HubSpot’s free email marketing tool is bundled inside its free CRM, which means you get contact management, deal tracking, forms, and email together at no cost. The email limit is 2,000 sends per month with HubSpot branding. There is no specific contact cap for the CRM itself, but email features are tied to the broader Marketing Hub ecosystem, which gets expensive fast.
For a team that already uses HubSpot for sales or customer management, adding the free email marketing tool makes sense. Your contact data, engagement history, and pipeline stages all live in the same system. The email editor is functional but not best-in-class. Template variety is limited on the free tier, and you cannot remove HubSpot branding without upgrading to Starter at $15 per month for 1,000 marketing contacts.
The real cost of HubSpot reveals itself at scale. The Professional tier starts at $890 per month with a mandatory $3,000 onboarding fee. Even the Starter plan at 5,000 contacts costs $215 per month. HubSpot’s free plan is a gateway to one of the most expensive marketing platforms on the market. It works beautifully as a CRM-first solution for teams that need unified data, but it is not where you want to be if email marketing is your primary use case and budget is a constraint.
Klaviyo’s free plan supports 250 active profiles and 500 email sends per month. Those limits are tight, but Klaviyo earns its spot here because of what it does within those limits. Deep Shopify and WooCommerce integrations, revenue-attributed reporting, pre-built e-commerce flows for abandoned carts, post-purchase follow-ups, and win-back sequences all work on the free tier. If you run an online store with a small customer base, Klaviyo gives you the most sophisticated automation logic at zero cost.
The trade-off is that Klaviyo is expensive once you grow. At 1,000 contacts, the Email plan costs $30 per month. At 5,000 contacts, it reaches $100 per month. At 10,000, you are paying $150 per month. These prices are competitive within the e-commerce niche but significantly higher than general-purpose platforms like Mailsoftly or Brevo. Klaviyo also limits its value outside e-commerce. If you are a service business, a content creator, or a SaaS company, the platform’s features and templates are not designed for your use case.
Mailchimp’s brand recognition is unmatched. It is the platform most people think of first when they hear “email marketing.” Unfortunately, its free plan no longer matches that reputation. In 2026, the free tier gives you 250 contacts and 500 email sends per month. That is enough for a personal project or a micro-newsletter, but it is not enough to run a business campaign with any real frequency. You also get Mailchimp branding on every email, limited automation, and no A/B testing.
The free plan has shrunk repeatedly over the years. It used to offer 2,000 contacts and 10,000 sends. Then it dropped to 500 contacts. Now it sits at 250. Each reduction has pushed more users toward the Essentials plan, which starts at $13 per month for 500 contacts. The Standard plan, which unlocks the features most businesses actually need (send-time optimization, behavioral targeting, advanced segmentation), starts at $20 per month for 500 contacts and climbs to $100 at 5,000 contacts.
Mailchimp still has one of the largest template libraries and integration ecosystems in the industry. If your workflow depends on a specific third-party tool, Mailchimp probably connects to it. But if you are choosing purely on free plan value, Mailchimp sits at the bottom of this list. Every other tool here gives you more contacts, more sends, or fewer restrictions for the same price of zero.
The comparison table makes the raw numbers clear, but the right choice depends on your specific situation. Here is a decision framework based on the most common scenarios.
One factor that does not show up in feature lists is what happens when you hit the free plan ceiling. Some platforms make upgrading seamless: same interface, same features, higher limits. Others gate critical features behind mid-tier plans, forcing you to pay for tools you assumed were included. Before choosing your free email marketing tool, open the pricing page and check what the first paid tier actually costs at your projected list size six months from now. That number matters more than any free plan comparison.
Free plans are starting points, not destinations. Here is what the first meaningful paid tier costs on each platform when your list hits common growth milestones.
| Platform | At 1,000 Contacts | At 5,000 Contacts |
|---|---|---|
| Mailsoftly (Basic, annual) | $39/mo (covers up to 5K) | $39/mo |
| Mailchimp (Essentials) | $26.50/mo | $75/mo |
| Kit (Creator) | $39/mo | $89/mo |
| Klaviyo (Email) | $30/mo | $100/mo |
| HubSpot (Starter) | $15/mo | $215/mo |
The pattern is clear. Several platforms offer low entry prices at 1,000 contacts but escalate sharply by 5,000. Mailsoftly’s Basic plan covers the entire range from 1,000 to 5,000 contacts at a single annual rate of $39 per month, making it the most predictable upgrade for growing businesses. HubSpot shows the most dramatic cost increase, jumping from $15 to $215 as you add marketing contacts to the Starter tier.

500 contacts, 2,000 emails per month. Free hands-on migration. No credit card.
For the broader picture on this topic, see our complete Email Marketing guide, which covers strategy, fundamentals, and advanced playbooks.
Mailsoftly offers the best balance for growing businesses. Its free plan includes 500 contacts, 2,000 emails per month, automation, segmentation, and zero branding on sent emails. Most competitors either cap contacts lower (Mailchimp at 250), restrict features (Kit limits you to one automation), or add their logo to your campaigns (Brevo, MailerLite, HubSpot). Mailsoftly also provides the smoothest upgrade path, with the Basic plan covering up to 5,000 contacts for $39 per month on annual billing.
Yes, Mailchimp still offers a free plan, but it has become significantly more restrictive. The current free tier supports only 250 contacts and 500 email sends per month. Mailchimp branding appears on every email, and advanced features like A/B testing and send-time optimization are not available. For context, Mailchimp’s free plan once supported 2,000 contacts and 10,000 sends. The current version is a shadow of that original offering.
Kit (formerly ConvertKit) is the only platform on this list that allows up to 10,000 subscribers on a free plan. However, you are limited to one automation, Kit branding is added to every email, and advanced reporting is not available. Brevo also allows unlimited contacts on its free plan but caps sends at 300 per day. If you need to send to 10,000 subscribers with full automation and no branding, a paid plan is required on every major platform.
Brevo charges by email volume, not by contact count. All plans, including the free tier, allow unlimited contacts. The free plan limits you to 300 emails per day. Paid plans start at $9 per month for 5,000 emails and scale based on how many emails you send, regardless of how many contacts are in your account. This model benefits businesses with large lists and low send frequencies.
Focus on five factors: the contact limit, the monthly send limit, whether the platform adds its branding to your emails, which features are available at the free tier (especially automation and segmentation), and the cost of the first paid plan at your projected list size in six months. A free plan that forces an expensive upgrade at 500 contacts costs more in the long run than a plan with slightly lower limits but a gentler pricing curve. Check the upgrade path before you commit, not after you have built your workflows.
