Best Email Marketing Tools Under $50/Month (2026): Real Prices

This post contains affiliate links. See our disclosure.

Email still pays. It’s the one channel you own, and no algorithm decides who sees your message. Yet most small businesses buy features they never use: multi-channel journeys, predictive analytics, ten seats for a team of one.

This guide is for shops and solo operators with lists up to a few thousand contacts who want to stay under $50/month. We priced each tool at realistic list sizes, not just the “from” price on the homepage. All prices are in USD from each vendor’s official pages as of October 2026. Where a vendor doesn’t publish a price for a given list size, we say so rather than guess.

Quick answer: our verdict

• Best overall under $50: MailerLite. Comfort costs $19/month at 1,000 subscribers and $33/month at 2,500 (monthly billing, as of October 2026), with automations, landing pages and an AI writing assistant included. Try MailerLite
• Best free-to-start: Kit. The free Newsletter plan covers up to 10,000 subscribers with unlimited broadcasts (as of October 2026). Automations need the $39/month Creator plan. Try Kit
• Best for ecommerce on a budget: Brevo. Pricing is based on emails sent rather than list size. Free gives you 300 emails/day, and Standard with marketing automation starts at $18/month (as of October 2026). Try Brevo
• Best simple newsletters: Kit, with Sender as the budget alternative: free for up to 2,500 subscribers and 15,000 emails/month (as of October 2026). Try Sender
• Honorable mention for Shopify stores: Klaviyo. It’s strong for ecommerce. The Email plan starts at $20/month for 251–500 active profiles (as of October 2026), and the price rises as your list grows. Try Klaviyo

Pricing footnotes: MailerLite tiers come from MailerLite’s published pricing tables (monthly billing; annual saves 10%). Kit’s $39/month Creator price is for up to 1,000 subscribers. Brevo prices by monthly email volume, and each tier caps how many contacts you can store. Klaviyo publishes its $20/month entry price for 251–500 active profiles. Use its pricing page for larger lists.

What you actually need

For a small business sending a few thousand emails a month, the must-haves are short:

• Signup forms and one landing page to grow the list.
• A welcome automation that sends automatically when someone joins.
• Tags or segments so buyers and non-buyers get different emails.
• Domain authentication (SPF, DKIM, DMARC) for deliverability.
• An editor you’ll actually use. Plain-text-style emails are fine.
• Ecommerce integration if you sell physical products (Shopify, WooCommerce), for abandoned-cart and post-purchase flows.

Things you probably don’t need yet: predictive analytics, multi-brand management, dedicated IPs, WhatsApp campaigns, and more than two or three seats.

Tool roundup

1. MailerLite: best overall under $50

MailerLite renamed its plans in June 2026 to Free, Comfort, Power and Enterprise. As of October 2026: Free covers 250 subscribers, 2,500 emails/month and 2 seats. Comfort is $12/month at 500 subscribers, $19 at 1,000, $33 at 2,500 and $49 at 5,000. Power is $25 at 500, $39 at 1,000 and $49 at 2,500. Those are monthly-billing prices, and annual billing saves 10%. Comfort lets you send 10x your tier ceiling each month. Power removes the sending cap.

Every paid plan gets the full feature set, so you only pay more for a bigger list or more sending. Comfort includes 50 automations, 10 forms, 10 sites, 5 digital products, 3 seats and MailerLite’s AI tools (HeyLite).

Pros

• Stays under $50/month on Comfort up to 5,000 subscribers (as of October 2026).
• Automations, landing pages, websites and an AI writing assistant included.
• Sells digital products and paid newsletters.
• 14-day trial of premium features, no card required.

Cons

• The free plan dropped to 250 subscribers, so it’s a launchpad, not a long-term home.
• Paid plans auto-upgrade to the next tier when you pass your subscriber limit.
• Accounts must be approved before you can send.

Try MailerLite

2. Kit (formerly ConvertKit): best free-to-start and best for newsletters

Kit’s free Newsletter plan supports up to 10,000 subscribers with unlimited broadcasts, forms and landing pages, tagging and segmentation, digital product sales, and A/B testing on broadcasts (as of October 2026). The catch is that visual automations and email sequences require a paid plan. Creator is $39/month, or $390/year, at 1,000 subscribers, and Creator Pro is $79/month at the same tier. Both come with a 14-day free trial.

Pros

• The most generous free subscriber limit on this list.
• Built for creators: paid newsletters, tip jars, recommendations.
• Free migration service on paid plans.
• Clean, simple editor that suits text-first newsletters.

Cons

• No automations or sequences on the free plan.
• At $39/month for 1,000 subscribers, Creator costs about twice MailerLite Comfort at the same size.
• Creator pricing rises as your list grows, so check the price at your subscriber count.

3. Brevo: best for ecommerce on a budget

Brevo charges mainly by monthly email volume, not list size. The Free plan sends 300 emails/day and stores up to 100,000 contacts, with marketing automation for up to 2,000 contacts. As of October 2026, Starter starts at $9/month (5,000 emails/month, up to 500 contacts, no daily limit). Standard starts at $18/month and adds unlimited marketing automation, A/B testing, AI send-time optimization, web and event tracking, a landing page, and no Brevo logo. Higher Starter and Standard tiers raise both sends and contact storage: 10,000 emails for up to 1,500 contacts and 15,000 emails for up to 2,500 contacts. Check Brevo’s pricing page for the price at your volume.

Pros

• A free plan with automation and a big contact allowance.
• Transactional email included on all plans, which is handy for stores.
• SMS and web push are available as you grow.
• Annual billing saves 10%.

Cons

• On Starter, removing the Brevo logo is a paid add-on (it’s included from Standard up).
• Contact caps on the lower paid tiers auto-upgrade you when exceeded.
• The interface covers a lot (sales, chat, SMS), so there’s more to learn than with a pure newsletter tool.

Try Brevo

4. Sender: best for very tight budgets

Sender’s Free Forever plan covers up to 2,500 subscribers and 15,000 emails/month with automation, landing pages, signup forms and popups, and transactional email (as of October 2026). Free emails carry Sender branding. New accounts get a 14-day Professional trial with no card. Paid Standard and Professional plans remove the branding and add more seats and features. Sender’s pricing page shows first-year discounts on paid plans, so check the renewal price for your list size before you commit.

Pros

• A large free allowance for a small list.
• Automation included on the free plan.
• No daily sending limits.

Cons

• Sender branding on the free plan.
• The free plan includes only 1 seat.
• Promo pricing makes the long-term cost harder to compare.

Try Sender

5. Klaviyo: honorable mention for Shopify stores

Klaviyo’s free plan covers 250 active profiles and 500 emails/month, plus $5 of mobile messages (as of October 2026). It’s the ecommerce specialist: deep store data, segmentation and revenue attribution. The paid Email plan starts at $20/month for 251–500 active profiles (as of October 2026). Prices rise with active profiles, so check Klaviyo’s pricing page at your list size.

Pros

• Built for ecommerce: store data drives segments and flows.
• Revenue attribution for campaigns.
• Email and SMS in one place.

Cons

• Pricing scales with active profiles, so check whether your list size fits a $50 budget.
• Free-plan email support lasts only the first 60 days.
• Overkill for service businesses.

Try Klaviyo

Who each tool is best for

• MailerLite: most small businesses, consultants and service providers who want automations under $50.
• Kit: creators and writers whose main product is the newsletter, especially lists under 10,000 that don’t need automations yet.
• Brevo: stores and businesses that send transactional and marketing email and have large lists but send infrequently.
• Sender: anyone with up to 2,500 subscribers who wants to pay $0 and doesn’t mind the branding.
• Klaviyo: Shopify-first ecommerce brands with revenue to justify the cost.

Deliverability mistakes that waste your money

1. Skipping domain authentication. Since 2024, Gmail and Yahoo require bulk senders to authenticate with SPF and DKIM, publish a DMARC record, and offer one-click unsubscribe. Set this up on day one, and send from your own domain, not a free Gmail address.
2. Importing old or bought lists. Purchased lists violate most providers’ terms and get accounts suspended. Old lists cause bounces and spam complaints.
3. Never cleaning your list. Most tools here bill by active subscribers. Removing people who haven’t opened in months saves money and protects your sender reputation.
4. Image-only emails. Heavy designs with little text often land in Promotions or spam. Plain, personal emails work fine for small businesses.
5. Inconsistent sending. Going silent for three months and then blasting your whole list invites complaints. Pick a steady rhythm.

Starter automation map

You don’t need dozens of flows. Start with these five, in this order:

1. Welcome sequence (3 emails over a week): deliver the lead magnet, introduce yourself, make one soft offer.
2. Lead magnet delivery: an instant email with the download, tagged by source.
3. Post-purchase follow-up: thank-you, how-to-use tips, and a review request after a few days.
4. Abandoned cart or abandoned booking: one or two reminders (stores and booking-based services).
5. Re-engagement: a “still want to hear from us?” email to inactive subscribers, then remove anyone who doesn’t respond.

Note that Kit’s free plan doesn’t include automations, and MailerLite Free allows only 3 active automations (as of October 2026).

StackPilot recommendation

For most small businesses, MailerLite Comfort is the best value under $50/month: $19 at 1,000 subscribers and $33 at 2,500 (as of October 2026), with automations included. If you’re a creator starting from zero, start on Kit’s free plan and upgrade once you need a welcome sequence. If you run a store, compare Brevo (volume-based pricing) against Klaviyo (ecommerce depth) at your real list size before you decide.

FAQ

What is the cheapest email marketing tool for a small business?

For small lists, several are free. As of October 2026, Kit is free up to 10,000 subscribers (no automations), Sender up to 2,500 subscribers, and Brevo for 300 emails/day. For automations under $20/month, MailerLite Comfort costs $19 at 1,000 subscribers.

Is MailerLite still free?

Yes, but since the June 2026 changes, the free plan covers 250 subscribers and 2,500 emails/month. It’s best treated as a starter plan.

Kit vs MailerLite: which is better?

Kit is better if you want a free plan for a large newsletter list. MailerLite is better if you need automations, landing pages and a website under $50/month.

Do I need an ecommerce-specific tool like Klaviyo?

Not at first. MailerLite integrates with Shopify and WooCommerce and supports abandoned-cart automations. Brevo also has Shopify and WooCommerce integrations. Consider Klaviyo once email revenue justifies the higher price.

How many emails should a small business send?

Consistency matters more than frequency. A weekly or twice-monthly email that people expect beats sporadic blasts.

Why does my price go up automatically?

Most of these tools bill by active subscribers or contacts and move you to the next tier when you pass your limit. Cleaning inactive subscribers regularly keeps your bill down.
