For small business owners, email marketing still delivers the highest return of any digital channel. Direct access. No algorithm to fight. No middleman deciding who sees your work.
The challenge is software cost. Most platforms charge more as your list grows. The wrong pick can eat your profit margin before you send a single campaign.
I have tested these tools for years across a small e-commerce store, a freelance newsletter, and a local service business. The picks below are the ones I would buy again on a lean budget.

What "Budget" Really Means for Email Tools
Budget software is not just "cheap." It needs three things:
- Free or low starting price
- Real features on the cheap plan
- A clear upgrade path when your list grows
A free plan that hides the autoresponder behind a $49 paywall is not budget-friendly. A paid plan that costs $13 but covers 20,000 contacts is a steal.
Look at price per contact, not just monthly fee. A $10 plan with 1,000 contacts sounds fair. A $20 plan with 20,000 contacts is far cheaper per subscriber.
MailerLite: The Best Overall Budget Pick

The free plan covers 1,000 subscribers and 12,000 emails a month. That is enough for most businesses just starting. The drag-and-drop editor is clean. Landing pages work without extra plugins. Sign-up forms are easy to embed.
Pricing stays gentle as you scale. The paid plan starts around $10 a month and unlocks automations, A/B testing, and removing the MailerLite logo.
What I like most is the editor. It feels light. It does not slow my browser. Templates look modern, not stuck in a 2010 frame.
The catch: deliverability is solid but not the absolute best for cold lists. Warm up your sending domain before you import thousands of contacts.
Brevo: Best for Growing Lists on a Tight Budget
Brevo (formerly Sendinblue) wins on price-per-contact. That matters when your list is already past 5,000.
The free plan allows 300 emails a day, not a set monthly limit. If you email weekly, that is roughly 8,000 sends a month free. The paid Starter plan is around $9 a month and jumps to 20,000 emails monthly.
You also get transactional email, SMS, and a basic CRM. For service businesses that need appointment reminders, this saves the cost of a separate tool.
When I ran a local workshop business, I used Brevo for both newsletters and booking confirmations. One bill. One login. One deliverability reputation to manage.
The editor is a bit clunkier than MailerLite. But the price per send is hard to beat past 10,000 contacts.
Mailchimp: Best for Beginners Who Want Hand-Holding
Mailchimp is the name most people know. The free plan still covers 500 contacts and 1,000 sends a month.
It is friendly. Templates are polished. The dashboard explains each metric in plain words. If you have never sent a campaign, Mailchimp's guided setup removes most fear.
The pricing gets sharp once you cross 500 contacts. The Essentials plan starts near $13 a month. Advanced features like send-time optimization or multivariate testing jump to the $20+ tier.
Use Mailchimp if you value ease over price. Skip it if your list will grow fast and you want predictable scaling costs.
Other Tools Worth a Look
Three more platforms deserve a mention, depending on your needs:
- Moosend: Plans start near $9 a month with no subscriber cap on paid plans. Strong for plain newsletters with automations.
- MailPoet: A WordPress plugin, not a separate platform. Free for up to 1,000 subscribers if your site runs WordPress. Great for bloggers who already host with WP.
- ConvertKit (now Kit): Free plan covers 1,000 subscribers. Best for creators selling digital products. The paid tier is pricier than the others here, so it suits revenue-generating creators more than budget-tight shops.
Features You Should Not Skip
Cheap does not mean empty. Make sure your pick covers:
1. Automation: Welcome emails, abandoned cart, birthday discounts. The bare minimum is a 3-step welcome series.
2. Segmentation: Tag subscribers by interest, location, or purchase history. Generic blasts waste money.
3. Landing pages: Built-in saves a $20 monthly subscription to a separate builder.
4. Mobile preview: Over 60% of opens happen on phones. Test before sending.
5. List cleaning: Bounce and spam reports help you clean dead addresses before they hurt deliverability.
A Simple Picking Framework
Before you sign up, answer three questions:
- How big is your list today, and how fast will it grow?
- Do you need automations, or just one-off broadcasts?
- Will you stay under 1,000 contacts for at least a year?
If yes to the last one, the free tiers of MailerLite or Mailchimp will carry you. If you expect to grow past 5,000 quickly, Brevo's per-email pricing is safer. If you run WordPress and want zero extra logins, MailPoet is a hidden gem.
Common Budget Mistakes to Avoid
Small business owners often pick the wrong plan. Watch for these traps:
- Paying for subscribers you do not have. Some tools count unsubscribed contacts. Clean your list first.
- Ignoring the cost of add-ons. SMS, transactional email, or premium templates can double your bill.
- Skipping the free trial. Most platforms offer 14 to 30 days. Use them.
- Switching tools too often. Each move risks deliverability and burns hours. Stay put for at least 6 months.
My Honest Take After Years of Testing
MailerLite is the pick I recommend most often. It balances price, ease, and features for small shops under 5,000 contacts. Brevo wins when your list is bigger or you need transactional email in the same tool. Mailchimp is fine if you want the comfort of a familiar name and do not mind the steeper jump in cost.
The right answer depends on your list size, your skill level, and how fast you plan to grow. Pick the tool that fits your next 12 months, not your fears.
Frequently asked questions
What is the cheapest email marketing software with automations?
MailerLite and Moosend both offer automations on plans starting near $10 a month. Brevo also includes basic automations on its free and Starter plans, though with daily send limits instead of contact limits.
Can I switch email platforms later without losing subscribers?
Yes. Most platforms let you export your list as a CSV and import it into a new tool. Your templates and automations do not transfer, but your contact list and signup history usually do. Plan a 30-day overlap to warm up the new sending domain before you switch fully.
How many emails should I send per month as a small business?
For most small businesses, one to two emails a week is the sweet spot. Enough to stay in mind, not enough to annoy. Quality matters more than volume. A useful weekly tip beats a daily promo blast.
Is free email marketing software safe for my business?
Free plans from reputable tools like MailerLite, Brevo, and Mailchimp are safe. They use the same sending infrastructure as paid customers. The trade-off is limits on contacts, sends, or features like automations. Read the fine print on branding and unsubscribe handling before you send.
Do I need a paid plan to grow my list?
No. Free plans support list growth through signup forms and landing pages. You will need a paid plan once you want automations, advanced segmentation, or to remove the platform's footer logo from your emails.
