Cheapest Email Marketing Platforms in 2026: Official Pricing and Free Plans Compared

The cheapest good email marketing platform in 2026 is Brevo for most senders, because it charges by emails sent and every plan includes unlimited contacts. Sender has the most generous free plan (2,500 subscribers and 15,000 emails a month) and paid plans from $6.30 a month. SendPulse, an AI-driven email marketing and chatbot platform, is the cheapest all-in-one: its free-forever plan covers 15,000 emails a month, with chatbots, SMS, an SMTP service and a verifier in the same account.

Also consider MailerLite for a polished editor, EmailOctopus for simple newsletters and Kit for creators with big free lists. Mailchimp is worth it for integrations, and Buttondown suits tiny text newsletters.

How we compared the cheapest email marketing platforms

We read every price on the vendor’s own official pricing page on September 24–25, 2026, and compared what each plan really includes: subscriber and email limits, branding on free emails, and which features sit behind a paywall. Where a pricing page could not be read, we used 2026 pricing reviews and mark the figure “about”. We also checked each vendor’s own domain authentication with the lookups behind our DMARC checker.

What makes an email marketing platform cheap (and still good)

An affordable plan is only half the brief: the platform also has to be reliable enough to reach the inbox. Five things separate a good cheap tool from a false economy:

• Pricing model. Contact-based tools charge for every subscriber you store; email-based tools like Brevo charge for what you send. A big list you email twice a month is far cheaper on the second model.
• Free plan limits. Look at subscribers and monthly emails. A free plan with 2,500 subscribers but 10,000 emails lets you send four campaigns a month to the whole list.
• Branding and paywalls. Many free plans add the vendor’s logo to every email or hold back automation. Check what the cheapest paid tier unlocks.
• Deliverability basics. A cheap plan is no bargain if your mail lands in spam. Every platform here lets you authenticate your domain with SPF and DKIM; confirm it with our SPF checker.
• Growth cost. The cheapest plan at 500 contacts is not always the cheapest at 5,000. Check the official pricing page at the list size you expect next year.

The cheapest email marketing platforms in 2026

1. Brevo

Brevo is the cheapest good platform for most businesses because it charges by emails sent, not contacts stored. If your list is large but you send a couple of campaigns a month, nothing here costs less. Paid plans start at about $9 a month for 5,000 emails.

The free plan sends 300 emails a day to an unlimited list and includes transactional email, SMS and a simple CRM. Free and Starter emails carry the Brevo logo unless you pay to remove it, and automation is less deep than ActiveCampaign’s.

2. Sender

Sender’s free plan is the most generous here by list size and volume: 2,500 subscribers, 15,000 emails a month, automation, landing pages, pop-ups and even transactional email.

Paid plans start at $6.30 a month for 500 subscribers on annual billing and remove Sender branding. The trade-offs are a smaller ecosystem, a single seat on the free plan, and a DMARC policy on its own domain set to quarantine rather than reject.

3. SendPulse

SendPulse is an AI-driven email marketing and chatbot platform built for scaling businesses, and it is the cheapest way here to get more than email in one account. It helps you attract leads and convert them into customers: its free-forever plan covers up to 500 subscribers and 15,000 emails a month, and paid plans start at about $8 a month for 500 subscribers on annual billing.

What makes it good value is what the price includes. SendPulse combines marketing, sales and support in one platform: automated funnels, a CRM that unifies every channel, and chatbots for Instagram, Facebook, WhatsApp, Telegram, TikTok and Viber. It also covers SMS, web push, pop-up forms and a website builder. An SMTP service (12,000 free transactional emails a month) and an email verifier (100 free checks a month) mean you do not pay for separate tools.

SendPulse is an international company with an office in Brazil; it is a Meta Partner and an official WhatsApp Business API provider, and it integrates with 40+ services. On the downside, pricing scales with subscriber count, and the many channels bring a learning curve if you only need email. It also does not yet publish a BIMI record on its own domain.

4. MailerLite

MailerLite’s editor, landing pages and website builder feel more polished than most budget tools, and paid plans start at $12 a month on Comfort.

Its free plan has shrunk to 250 subscribers and 2,500 emails a month, and paid prices rose in 2025. On price it now loses to Sender, EmailOctopus and Kit for anyone past a few hundred contacts, and it offers no chat or WhatsApp.

5. EmailOctopus

EmailOctopus keeps things simple: a clean editor, forms and landing pages, and low prices. The free Starter plan covers 2,500 subscribers and 10,000 emails a month, with EmailOctopus branding and reports kept for 30 days.

Pro, from $9 a month on annual billing, removes branding and adds unlimited landing pages, forms and users. Automation is basic compared with Sender or SendPulse.

6. Kit

Kit’s free plan allows the most subscribers of any tool here, up to 10,000, with unlimited landing pages, forms and broadcasts. For a creator with a big list and no automation needs, that is hard to beat.

Automations and sequences need the Creator plan, from $33 a month for 1,000 subscribers, which is expensive per subscriber compared with Brevo or Sender. Email designs are also plainer.

7. Mailchimp

Mailchimp is the best-known name and has the most integrations, but it is rarely the cheapest option. The free plan covers 250 contacts and 500 sends a month. Essentials is $13 a month for the first 12 months thanks to a 50% introductory discount, then roughly double, and contact-based pricing climbs quickly as your list grows.

It earns a place for teams that need a specific integration or want the easiest onboarding and will pay for it. Essentials also limits automations to four steps.

8. Buttondown

Buttondown is a minimalist newsletter tool with a markdown editor, custom sending domains and hosted archives. It is free for the first 100 subscribers, and you pay only for active subscribers plus the add-ons you pick, from $9 a month each.

It suits writers and developers; it is not built for ecommerce or complex marketing, and add-ons add up quickly.

Which email marketing platforms stay free at 2,500 subscribers?

A common small-list size is 2,500 subscribers. Based on each vendor’s official free-plan limits, here is who still charges nothing at that size:

Hidden costs on cheap email marketing plans

• Branding removal. Brevo and EmailOctopus add their logo to free emails; removing it costs an upgrade or add-on.
• Send caps. A daily cap (Brevo free: 300 a day) or a monthly cap (EmailOctopus free: 10,000) can block a big announcement.
• Seats. Free plans often include one user; extra seats push you to paid tiers.
• Contact growth. Contact-based pricing rises every time your list crosses a tier, even if you send the same number of emails.
• Introductory discounts. Mailchimp’s first-year 50% discount doubles at renewal; budget for the regular price.
• Add-ons. Buttondown and Brevo sell features individually, which is cheap for one feature and expensive for five.

Do cheap platforms hurt deliverability?

Not by themselves. Inbox placement depends far more on your list quality and authentication than on the price you pay. All eight platforms let you set up SPF and DKIM on your own domain. As a trust signal, we checked how each vendor protects its own domain:

Checked with public DNS on September 25, 2026. After you connect a platform, run your domain through the free sender reputation checker.
