Best Email Marketing for Small Business (2026)

A small business needs an email tool that is cheap at a few hundred contacts, quick to learn, and still usable when the list reaches a few thousand. Nobody on staff has “email marketing” as their whole job, so the tool has to stay out of the way.

Below are five platforms that fit that brief, with prices checked against each vendor’s pricing page on October 5, 2026. After the tool picks there is a section on how the setup changes for three common business types: gyms and studios, restaurants and cafes, and event organizers.

What Small Businesses Should Look for

• Pricing that grows in small steps. Some tools jump sharply between the first and second contact tier. Check the price at the list size you expect in a year, not only the entry price.
• A free plan or trial you can run a real campaign on. You learn more from one actual send than from any comparison chart.
• Automation on the plan you can afford. A welcome email and a re-engagement flow do most of the work for a small business. Some vendors put automation on a higher tier.
• SMS if your messages are time-sensitive. Class reminders and “table free tonight” texts get seen faster than email.
• Integrations with the system that holds your customers. For many local businesses that is a booking tool, a POS or a ticketing platform, not an online store.

Quick Comparison

Tool	Best for	Free plan	Entry paid plan (monthly billing)
MailerLite	Most small businesses	250 subscribers, 2,500 emails/month	Comfort, $12/month for 500 subscribers
Brevo	Email plus SMS in one account	300 emails/day	Starter, $9/month for 5,000 emails and 500 contacts
Sender	Large free list, low paid price	2,500 subscribers, 15,000 emails/month	Standard, $9/month for 500 subscribers
EmailOctopus	Simple newsletters	2,500 subscribers, 10,000 emails/month	Pro, from $10/month
Moosend	Automation on a budget	None (30-day trial)	Pro, $9/month for 500 contacts

Our Top Pick: MailerLite

MailerLite is the best starting point for most small businesses. The editor is clean, the automation builder is easy to follow, and the paid plans start low.

The free plan is smaller than it used to be: 250 subscribers and 2,500 emails a month, with 3 automations, 1 landing page and 3 signup forms. That is enough to set up a welcome sequence and test your first campaigns, but an established business with an existing customer list will land on a paid plan right away.

Comfort starts at $12 a month for 500 subscribers and Power at $25 a month. Annual billing saves 10%, and nonprofits get 30% off. Above 500 subscribers the price comes from a calculator, so check the MailerLite pricing page at your list size. For comparison, Mailchimp’s Essentials plan starts at $13 a month for 500 contacts, and Mailchimp’s free plan is down to 250 contacts and 500 emails a month.

The weak spots: MailerLite has no SMS in its email marketing plans, so text reminders need a second tool, and the template library is smaller than Mailchimp’s. For the full breakdown, see our MailerLite review.

Brevo: Email and SMS from One Account

Brevo runs email and SMS from the same contact list and campaign builder, which suits businesses that send short, urgent messages: class reminders, last-minute availability, day-of event logistics. Brevo can also send WhatsApp campaigns. SMS credits are sold separately from the email plan, so price your expected text volume before you commit.

Pricing is built mainly around monthly email volume rather than list size. The free plan lets you send up to 300 emails a day. Starter costs $9 a month for 5,000 emails, and that entry tier includes 500 contacts, so check the plan configurator if your list is larger. Standard, at $18 a month, is where marketing automation, A/B testing and landing pages come in. Starter does not include marketing automation, which matters if you want reminder sequences rather than one-off sends.

The interface is busier than MailerLite’s, and someone new to email marketing will need more time to find their way around. The details are in our Brevo review, or see Brevo alternatives.

Sender: Best Budget Option

Sender has the most generous free plan here: up to 2,500 subscribers and 15,000 emails a month, with email automation, landing pages and signup forms included. Free emails carry Sender branding.

The Standard plan costs $9 a month on monthly billing for 500 subscribers and 6,000 emails a month. It removes the branding and adds SMS messaging, A/B testing and 3 user seats. Professional, at $15 a month for 500 subscribers, raises the send limit to 12,000 emails and adds advanced automation. Sender offers 30% off the first year on annual billing for new customers.

The trade-off is a smaller ecosystem. Sender’s integrations cover the common ground (WordPress, WooCommerce, PrestaShop, Zapier), but the list is shorter than MailerLite’s or Mailchimp’s. Read our Sender review or the Sender pricing breakdown.

EmailOctopus: Best for Simplicity

EmailOctopus is for businesses that want to send a regular newsletter and a few automated emails without learning a large platform. The interface is minimal and a campaign takes minutes to put together.

The free plan covers 2,500 subscribers and 10,000 emails a month, with EmailOctopus branding, one landing page, one form and one user. Reports are kept for 30 days on free. Pro starts at $10 a month on monthly billing ($9 a month billed yearly) and removes the branding, unlocks unlimited landing pages, forms and users, and keeps reports forever. The entry Pro tier still caps sends at 10,000 emails a month.

Automation covers welcome sequences and drip campaigns. If you need complex branching, look at MailerLite or Moosend instead. See our EmailOctopus review for more detail.

Moosend: Automation on a Budget

Moosend gives you a capable automation builder at an entry price close to the cheapest tools here. It has pre-built workflow templates (Moosend calls them recipes) for common flows, and the Pro plan includes unlimited email sends, landing pages and signup forms.

Pro costs $9 a month on monthly billing for 500 contacts, with 20% off on annual billing. Higher tiers come from a calculator on the pricing page. There is no free plan; instead you get a 30-day trial with unlimited sends for up to 1,000 contacts and no credit card required.

The limitation for small businesses is the smaller integration library and template selection. For our full take, read the Moosend review or the Moosend alternatives guide.

Comparing the Top Tools

By Business Type

The tools above work for most small businesses. What changes between a gym, a restaurant and an event organizer is which integrations and channels matter. All integrations below are listed in each vendor’s own integrations directory as of October 2026.

Gyms, studios and personal trainers

A gym’s biggest email job is retention. Members who drift away rarely cancel straight away: attendance drops first, then the cancellation follows weeks later. Email and SMS are the cheapest way to catch that drift.

• Connect your booking tool. MailerLite and Mailchimp both list integrations with Acuity Scheduling and Calendly, so bookings can add or tag contacts automatically. If your studio runs on a different booking system, check whether it connects directly or through Zapier before you choose.
• Send class reminders by SMS. A text a couple of hours before a session is more likely to be seen than an email. Brevo (all plans, SMS credits extra) and Sender (paid plans) handle both channels from one list. MailerLite has no SMS, so pair it with a separate texting tool if reminders matter.
• Build a re-engagement flow. Segment members who have not opened in 60 to 90 days, or tag members who have not booked recently if your booking tool passes that data through, and send a personal check-in rather than a promotion.
• Use date-based emails tied to a membership start date: a check-in after the first two weeks, another at 90 days, and a renewal note before the term ends.

Restaurants and cafes

Restaurants usually have more past guests than active subscribers, and most of the value is in a consistent weekly email to regulars.

• Collect addresses where guests already are. A QR code on the table, a sign at the host stand, or an opt-in checkbox on your reservation or online ordering form.
• Connect the POS or reservation system. Mailchimp’s directory lists integrations with Square (POS and online store) and OpenTable. Brevo lists a Square integration as well. If you use a different POS, check its own marketplace for a connector.
• Time the weekly email for when people plan. Specials sent early in the week reach people while they are still deciding where to eat that weekend.
• Use SMS for last-minute fills. A “two tables free tonight” text works on a slow evening in a way an email rarely does. Brevo and Sender’s paid plans can send it from the same contact list.
• Make birthday offers worth opening. A free dessert or a drink beats a discount so small it reads as an afterthought.

Event organizers

Events need a sequence, not a single announcement. The tool matters less than the schedule and whether you can exclude people who already registered.

• Connect the ticketing or webinar platform. MailerLite’s directory lists Eventbrite and Zoom integrations, so registrations can flow into your list without CSV exports. Test the connection with a dummy event before you announce anything.
• If you run webinars, GetResponse hosts them inside the email platform on its Creator plan and above, which removes the integration step entirely. See the GetResponse pricing breakdown for plan details.
• Use SMS for day-of logistics when an email might sit unread.

A send timeline that fits most events with a registration step:

1. Announcement, 4 to 6 weeks out. Date, place or link, and one registration button.
2. Early-bird or speaker highlight, 3 weeks out. A second reason to act. Send it only to people who have not registered.
3. Last-chance email, 1 week out. Short, plain, with the deadline.
4. Confirmation, right after signup. Automated, with a calendar file attached.
5. Reminder, 24 hours before. Logistics: parking, join link, what to bring.
6. Final reminder, 1 hour before (online events). The link and nothing else.
7. Follow-up, the next day. Thank attendees, share slides or photos, ask for feedback. Send no-shows the replay or the next date.

Steps 2 and 3 depend on exclusion, so your tool must tag or segment people when they register. That works best when registration happens inside the email tool or through a native integration.

Common Mistakes

Choosing on brand name alone

A familiar name does not mean the best value. Mailchimp is the best-known tool, but its free plan now stops at 250 contacts and its paid plans cost more than MailerLite or Sender at the same list size. Our Mailchimp alternatives guide covers the options.

Ignoring list hygiene

Bounced and disengaged contacts hurt your sender reputation even on a list of 500. Remove invalid addresses, and run a re-engagement email before you delete inactive subscribers.

Paying for features you do not use

If your plan is a weekly newsletter and a welcome sequence, you do not need a CRM, webinar hosting or multi-channel automation. Start simple and upgrade when a real need appears.

Comparing entry prices instead of your real price

The cheapest tool at 500 contacts is often not the cheapest at 4,000. Run your actual list size through each vendor’s pricing calculator before you decide. Our email marketing pricing comparison lays out the tiers side by side.

Frequently Asked Questions

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

Sender has the largest free plan here (2,500 subscribers and 15,000 emails a month), and its Standard plan starts at $9 a month for 500 subscribers. Moosend’s Pro plan also starts at $9 a month for 500 contacts, with unlimited sends. MailerLite’s Comfort plan is $12 a month for 500 subscribers.

Can I use a free email marketing plan for my business?

Yes. The free plans from MailerLite, Brevo, Sender and EmailOctopus can all be used for business email. Most add the vendor’s branding to your emails, which you remove by upgrading. For more no-cost options, see our best free email marketing tools guide.

Do I need SMS as well as email?

Only if your messages are time-sensitive. Gyms sending class reminders, restaurants filling last-minute tables and event organizers sending day-of logistics get real use from it. Our email and SMS tools page compares the options.

How many emails should a small business send per week?

One a week is a solid starting point, plus automated emails such as a welcome sequence. Consistency matters more than frequency. If you are starting from zero, our guide to building an email list and welcome sequence guide cover the first steps.

Summary

For most small businesses, MailerLite is the best starting point: an easy editor, real automation and a $12 entry price. If text messages are part of how you reach customers, Brevo puts email and SMS in one account. Sender gives you the largest free plan and a $9 paid tier, EmailOctopus keeps things minimal, and Moosend offers more automation than its price suggests.
