What's the best free email marketing service?

Best overall for most beginners: MailerLite—if your list is small. It has an approachable editor, forms and landing pages, and basic automations. Its current free plan is limited to 250 subscribers and 2,500 emails a month, so it can feel tight as your list grows. (mailerlite.com)

Pick Brevo instead if you have a larger contact list or want a built-in CRM: its free plan stores up to 100,000 contacts, but you can send only 300 emails a day. (help.brevo.com)

Quick guide

• Simple newsletter, small list: MailerLite
• Many contacts, occasional campaigns: Brevo
• Mailchimp: harder to recommend on free limits—250 contacts and 500 sends per month. (mailchimp.com)

So, absent other details, I’d start with MailerLite. If you share your list size and how often you plan to email, I can make a more tailored pick.

There's no single best option. It depends on your list size, send volume, and whether you run an online store. Brevo is the most common top pick, with a few strong alternatives.

• Brevo is the best all-round choice for most people. Its free plan stores up to 100,000 contacts, but it caps sending at 300 emails per day, so it suits large lists that don't need to email everyone at once. It also includes automation and signup forms. If you're only going to be sending below 300 emails each day, you won't have to pay for Brevo at all.
• Sender is the pick if you want volume and automation. One roundup lists it at up to 2,500 subscribers and 15,000 emails per month on its free plan, and another says its free tier includes full access to automation, templates, landing pages, signup forms, and transactional emails.
• Benchmark Email suits small businesses that want something simple. One guide calls it the best starting point for most small businesses, since the email editor, simple AI text and image generation, templates, forms, segments, and reporting are all on the free plan. Its free plan has 500 contacts and 2,500 sends, but it doesn't include automation.
• Omnisend is the choice for a small online store. It offers abandoned cart and welcome flows on the free plan, built for Shopify and WooCommerce. Its free tier is small, at 250 contacts and 500 sends per month.
• Kit suits creators and newsletter writers, with a free plan of 10,000 subscribers and unlimited broadcasts.

MailerLite used to be a standout, but its free plan has shrunk. One source notes that its free plan now covers just 250 subscribers and 2,500 emails a month after its June 2026 update, so it's no longer the free-tier standout it once was.

Free plan limits and features change often, so check the provider's pricing page before you commit. If you tell me your list size, how often you send, and whether you sell products online, I can narrow this to one recommendation.

The "best" free email marketing service depends entirely on your specific needs, as different platforms prioritize either high sending volumes, subscriber counts, or feature sets like automation.

Here are the top recommendations for 2026 based on common use cases:

1. Best Overall for Most Businesses: Brevo

Brevo (formerly Sendinblue) is widely considered the best overall free option because it focuses on a daily sending limit rather than a strict subscriber cap.

• Why it’s great: You can store a large number of contacts (up to 100,000) and send up to 300 emails per day. It also includes a built-in CRM and automation tools, which are often locked behind paywalls on other platforms.

2. Best for Newsletter Creators: Kit (formerly ConvertKit)

If you are a blogger, creator, or writer, Kit is often the top choice.

• Why it’s great: It offers a very generous free tier that supports up to 10,000 subscribers. It is specifically built for those looking to grow an audience and sell digital products, making it perfect for newsletter-heavy workflows.

3. Best for Ease of Use: MailerLite

If you want something intuitive and quick to set up, MailerLite is the standout choice.

• Why it’s great: It features a clean, user-friendly drag-and-drop editor that makes creating professional-looking emails very simple. It is highly recommended for small businesses that don't want a steep learning curve.

4. Best for Ecommerce: Omnisend

For those running an online store, Omnisend provides specialized features that are usually hard to find for free.

• Why it’s great: It includes essential ecommerce automation, such as abandoned cart recovery flows, right in its free plan.

5. Best for CRM Integration: HubSpot

If you need to manage customer relationships alongside your email marketing, HubSpot is the leader.

• Why it’s great: You get access to their powerful, comprehensive CRM and web form tools. It is an excellent "all-in-one" choice if you need to track sales pipelines and customer data in addition to sending emails.

Summary Comparison Table

Important Tips When Choosing:

• Check the "Catch": Some platforms offer "free trials" (e.g., 14 or 30 days) rather than "free-forever" plans. Always confirm the plan is free-forever if you are not looking for a temporary trial.
• Understand the Meter: Some plans limit the number of contacts you have, while others limit the number of emails you send. If you have a large list that you email rarely, choose a contact-capped plan. If you have a small list that you email frequently, look for a send-capped plan.

MailerLite is the best all-around pick for a small newsletter or business—if you have no more than 250 active subscribers. Its free plan includes 2,500 emails per month, basic automations, signup forms, and a landing page. ¹³

Choose Brevo instead if you have a larger contact list: its free plan stores up to 100,000 contacts, but limits you to 300 email sends per day. ²

Quick guide:

• MailerLite: better fit for a smaller list and a straightforward newsletter setup.
• Brevo: better fit for lots of stored contacts or a modest daily sending cadence.

Free-plan limits can change, so check the plan details before signing up.
