Free Emailing 2026: 6 Tested Tools for Micro and SMBs

Discover our comparison of the best free emailing tools in 2026. Limits, deliverability, automation: find the ideal solution to get started.

TL;DR

To find the best free emailing tool in 2026, your choice will depend on your project. Brevo is the most versatile and generous for micro-businesses and content creators. HubSpot is unbeatable if you want an integrated CRM from the start. For e-commerce, Klaviyo is the go-to expert. Free plans are excellent for starting out, but be aware of contact limits and the tool's logo, which will soon push you to opt for a paid plan.

As the founder of SaaS Radar, I've seen dozens of founders get into emailing. The promise of "free" is enticing, but it often hides constraints that can hinder your growth. The goal of this article is not to sell you dreams but to give you a clear and honest view of what you will (and won't) get with a free emailing solution. We will dissect the offers, talk deliverability, and see when transitioning to paid becomes inevitable. No bullshit, just the facts.

What Makes a "Good" Free Emailing Tool in 2026?

Before diving into the comparison, let's agree on the criteria. A good free tool isn’t just about a high number of contacts. It's a balance of several factors. First, reasonable sending and contact limits so you're not blocked after two weeks. Next, decent deliverability. Sending 10,000 emails that all land in spam is useless. The reputation of the platform's sending servers is crucial, even on a free plan.

The usability of the email editor is also a key point. You should be able to create a neat newsletter without spending three hours. Finally, additional features: a signup form, basic automation scenarios (like a welcome email), and simple statistical reports to understand what works. Almost systematically, the trade-off is the presence of the tool’s logo in your emails and limited or non-existent customer support. That's the price of free. Keep this in mind. For a broader analysis of free and paid options, check out our complete guide on the best email marketing tool 2026.

Brevo (formerly Sendinblue)

Who it's for: Micro-businesses, freelancers, and content creators looking for the most comprehensive and versatile free solution on the market.

Strengths: Brevo's free plan is by far one of the most generous. You can have unlimited contacts, which is very rare. The limit is on sends: 300 emails per day (or 9,000 per month). It's more than enough to start. Brevo also includes features often found only in paid plans elsewhere: basic marketing automation, chat, and even a mini-CRM. It’s a true all-in-one marketing platform.

Limits: The 300 emails/day limit can be restrictive if you have a list of more than 300 contacts and want to send a campaign to everyone at once. You’ll need to segment or plan over several days. The Brevo logo is obviously present on all emails. The email editor is powerful but might seem a bit less intuitive than Mailchimp's for a complete beginner.

Indicative Price: Free up to 300 emails/day. Paid plans start at €19/month to unlock more sends and remove the logo.

Mailchimp

Who it's for: The ultra-beginner with a very small contact list who prioritizes ease of use above all.

Strengths: Mailchimp has long been the king of emailing and its interface remains a model of simplicity and usability. Creating a campaign is child’s play. Its editor is pleasant and the templates are of good quality. It’s the perfect tool to send your very first newsletter hassle-free.

Limits: Mailchimp's free plan has shrunk significantly. Limited to 500 contacts and 1,000 sends per month (with a daily limit of 500), you'll quickly find it restrictive. Automations are virtually non-existent (a single welcome email) and customer support is limited to 30 days. It has become more of a lead product than a real long-term solution. Our comparison Brevo vs Mailchimp details this evolution.

Indicative Price: Free up to 500 contacts. Paid plans quickly become expensive, starting at €13/month but rapidly increasing with the number of contacts.

HubSpot

Who it's for: Entrepreneurs or SMBs who think long-term and want to integrate their emailing into a complete CRM ecosystem from the start.

Strengths: HubSpot’s strength is not its emailing tool alone but its integration into the free CRM. You can send 2,000 emails per month for free, but above all, you benefit from a unified customer database. Every interaction is tracked. It’s extremely powerful for segmenting and personalizing your communications as you grow. The free plan also includes landing pages, forms, and a chat.

Limits: The emailing tool itself is quite basic in its free version. The editor is less flexible than those of Brevo or Mailchimp. The 2,000 emails/month limit can be quickly reached. And of course, the HubSpot logo is highly visible. HubSpot's intention is clear: to let you experience the power of the ecosystem to convert you to the paid Marketing Hub.

Indicative Price: Free for 2,000 emails/month. Paid Marketing Hub plans are a significant investment, starting at €18/month but climbing quickly.

How to Choose the Right Tool to Start?

Faced with these options, the reflex is to choose the one that offers the most contacts or sends. That's a mistake. From my experience on SaaS Radar, I've learned one thing: migrating an emailing tool is a real hassle. You have to export your lists, lose your statistics, recreate your templates and automations. Choose wisely thinking about your needs in a year, not just today’s.

If you’re launching an online store, integration with your e-commerce platform like Shopify is crucial. A tool like Klaviyo will be a better bet, even if its free plan seems less generous at first glance. If you sell B2B services, the CRM aspect of HubSpot makes all the sense. If you’re a content creator, the flexibility and generosity of Brevo will be perfect. Don’t let the tool control you; choose one that aligns with your strategy. Emailing is just one brick in your stack; think about how it will integrate with the rest.

Klaviyo

Who it's for: E-commerce businesses, especially those on Shopify, who want ultra-advanced segmentation and automation based on purchase behavior.

Strengths: Klaviyo is the king of emailing for e-commerce. Its free plan allows up to 250 contacts and 500 email sends. What’s interesting is that you have access to most advanced features, even for free. Segmentations (customers who bought this product, cart abandonment, etc.) and automated scenarios are very powerful. Integration with Shopify is seamless and perfect.

Limits: The free plan is very limited in volume. 250 contacts is very little. It’s designed to launch your store and make your first sales. Once your business picks up, switching to paid is mandatory. The tool is also more complex to handle than its generalist competitors. For a more direct comparison, read our analysis Klaviyo vs Brevo for e-commerce.

Indicative Price: Free up to 250 contacts and 500 sends. Paid plans are based on the number of contacts and start around €20/month.

SendGrid

Who it's for: Developers and companies with a technical profile needing a robust solution for transactional emails and also wanting to manage marketing campaigns.

Strengths: SendGrid’s reputation in deliverability is excellent. That's their core business. The free plan is attractive: it allows storing up to 2,000 contacts and sending 6,000 emails per month. It’s a good option for those who want to manage both their welcome emails, password resets (transactional), and newsletters (marketing) from one platform. Their APIs are very comprehensive.

Limits: SendGrid is a much more technical tool. The interface for creating marketing campaigns is less intuitive and less rich in templates than dedicated platforms. It caters to an audience that isn’t afraid to get hands-on with code or spend time on configuration. It’s not the most "plug-and-play" solution.

Indicative Price: Free up to 2,000 contacts and 6,000 emails/month. Paid plans start at €18.50/month for more volume and features.

Loops

Who it's for: SaaS startups and tech products wanting to send emails based on user actions within their apps (onboarding, feature adoption, etc.).

Strengths: Loops takes a modern and refreshing approach to emailing. Instead of focusing on static lists, everything is based on events and dynamic audiences. It’s perfect for sending the right message at the right time in a user’s lifecycle. The editor is minimalist and very fast, designed for simple and effective emails. Their free plan allows up to 1,000 contacts, which is comfortable for starting out.

Limits: It's not a tool for massive promotional campaigns to an unsegmented list. Loops is not the right choice. It is designed for more targeted and contextual communication. Its approach may confuse those used to traditional tools like Mailchimp.

Indicative Price: Free up to 1,000 contacts. The paid plan starts at $49/month, positioning it in a more premium segment.

Comparison Table of Free Plans

To make it clearer, here’s a summary of the characteristics of the free plans we've reviewed.

Beyond Emailing: The Importance of Automation

An emailing tool, even free, does not exist in isolation. Its true power is revealed when it is connected to your other tools. This is where automation comes into play. Imagine: a new client pays via Stripe, is automatically added to a specific list in Brevo, and receives a welcome email sequence. This is possible thanks to tools like Zapier or Make.

Even with a free plan, check your platform’s integration capabilities. A tool that can easily connect to other services will save you headaches later. It’s one of the pillars of the no-code philosophy: making the tools communicate to increase efficiency without writing a single line of code. Don’t overlook this aspect, as it often justifies the switch to a paid plan: unlocking more advanced integrations.

Verdict: Which Free Emailing Platform to Choose in 2026?

There’s no single answer, only choices tailored to contexts. Here's my final recommendation, based on the profiles I see most often.

• For freelancers, content creators, or starting micro-businesses: Go for Brevo. It’s the most balanced and generous free offer. It will serve you well long before you feel cramped.

• For future e-commerce merchants (especially on Shopify): Start directly with Klaviyo. You’ll be limited in volume at first, but you'll build on sound and specialized foundations for your business. Later migration would be too costly in time and data.

• For companies thinking CRM and long-term: HubSpot is the sensible choice. Emailing is just an entry point to a powerful ecosystem that will structure your entire customer relationship.

• For technical profiles or SaaS startups: If you're comfortable with APIs and value transactional deliverability as much as marketing, SendGrid is a safe bet. If you have a product-led approach and want to communicate with users based on their actions, Loops is a modern and very relevant alternative.

The free emailing market is competitive. Take the time to test one or two of these solutions. The important thing is to choose a partner who can grow with you.
