Here's the uncomfortable truth about email marketing software: the pricing model is the product. Nearly every tool in this category charges by contact count, which means the bill grows precisely as your marketing succeeds. We call it the Mailchimp ceiling, because Mailchimp made the model famous — you start free, your list grows, and one day the tool that cost nothing costs more than your accounting software, and deleting subscribers to save money starts to sound reasonable. That's a broken incentive. The second truth is quieter: for a small business, deliverability basics — a warmed-up domain, proper authentication, a clean list — move revenue more than any automation builder ever will. Fancy branching sequences don't matter if the email lands in spam. We build an email marketing module ourselves, so read this list knowing that; our entry is marked, and every competitor gets its genuine strength.
How we picked.
- What the bill does when the list grows. Per-contact pricing is the category default, and it means your costs scale with your success. We looked hard at each vendor's meter — contacts, sends, or both — because the entry price tells you almost nothing about the year-two price.
- Deliverability fundamentals over feature count. Authentication support, list-hygiene tooling, and sender-reputation practices matter more for a small sender than the automation canvas. Every tool here can send a broadcast; not every setup gets it to the inbox.
- Honesty about free tiers. Several vendors offer free plans. Some are generous, some are bait. We say which.
Every claim is qualitative on purpose. We won't invent open-rate statistics or satisfaction scores, and where a competitor is simply good, we say so plainly.
1. Mewayz
Disclosure: Mewayz is our product — judge this entry accordingly.
Mewayz is an all-in-one business platform with 50+ modules on one flat fee, and email marketing is one of those modules rather than a separate metered subscription. That's our direct answer to the Mailchimp ceiling: there is no per-contact pricing, so a list of ten thousand costs what a list of five hundred costs. Growing your audience is supposed to be the goal, not a billing event. And because the email module lives next to the CRM, the store, and the website builder, your list isn't synced in from three other tools — the contact who bought from your store is the same record you email.
The honest limitation: dedicated email platforms go deeper than we do on deliverability tooling and automation builders. If you send at serious volume and need granular deliverability analytics, inbox-placement testing, or the kind of multi-branch visual automation canvas ActiveCampaign is known for, a specialist tool will take you further. Our module is built for small businesses that want to send good campaigns to their own customers without a second bill that grows every month. Also said plainly: email marketing sits on our paid tiers — the free plan covers Link in Bio, a vCard, an online store, and the website builder, not email.
- Best for: small businesses that want email in the same platform — and on the same flat bill — as their CRM, store, and website.
- Pricing model: one flat fee for the whole platform, no per-contact meter and no per-seat charges. See pricing.
- Watch out: deliverability analytics and automation depth trail the dedicated platforms below; high-volume senders with complex funnels may want a specialist.
2. Mailchimp
Mailchimp is the default for a reason: the editor is friendly, the templates are polished, the integrations are everywhere, and a beginner can send a respectable first campaign in an afternoon. It remains one of the easiest on-ramps in the category.
- Best for: first-time senders who want the shortest path from zero to a decent-looking campaign.
- Pricing model: contact-tiered across feature plans — the bill steps up as the list grows, and it counts unsubscribed and archived contacts toward the meter on some plans, which surprises people.
- Watch out: the ceiling that bears its name. The free tier has shrunk over the years, key features keep migrating up the plans, and a growing list marches you through the price tiers automatically. We break the model down in Mewayz vs Mailchimp.
3. ActiveCampaign
ActiveCampaign has the best automation builder in this list, and it isn't close. Branching sequences, behavioral triggers, site tracking, lead scoring — if your revenue genuinely depends on sophisticated automated journeys, this is the specialist tool the others imitate.
- Best for: businesses whose funnel runs on automation — multi-step nurture, behavioral triggers, sales handoffs.
- Pricing model: contact-tiered plus per-seat elements on the sales side; the bill grows on the exact axis you're trying to grow.
- Watch out: the power has a learning curve and a price to match, and most small businesses use a fraction of it. If you mainly send newsletters and the occasional promotion, you're paying for a machine you won't run. Full comparison in Mewayz vs ActiveCampaign.
4. Constant Contact
Constant Contact has been doing this for decades, and its strength is exactly that: reliability, phone support a non-technical owner can actually reach, and event and nonprofit features the trendier tools skip. It's the tool your local chamber of commerce recommends, and that's not an insult.
- Best for: local businesses, nonprofits, and event-driven organizations that value support and steadiness over cutting-edge features.
- Pricing model: contact-tiered monthly plans; no free tier, so the meter starts on day one.
- Watch out: you pay a premium relative to the features, and the automation is basic next to ActiveCampaign or even MailerLite. See Mewayz vs Constant Contact for the detail.
5. Kit (formerly ConvertKit)
Kit — the company renamed itself from ConvertKit in 2024, so both names float around — is built for creators, and it shows in the right ways: clean text-first emails, excellent tagging and segmentation, landing pages, and paid-newsletter and digital-product commerce built in. For a solo creator monetizing an audience, it's arguably the best-shaped tool on this list.
- Best for: creators, writers, and coaches whose business is the email list itself.
- Pricing model: subscriber-tiered with a free tier for small lists; the meter climbs with the audience, which for a creator is the whole game.
- Watch out: it's deliberately minimal on e-commerce and business features beyond the creator use case, and the visual polish of Mailchimp-style template design isn't the point here. We compare it in Mewayz vs Kit.
6. Brevo (formerly Sendinblue)
Brevo — renamed from Sendinblue in 2023 — is the notable pricing-model exception in this category: it charges primarily by emails sent, not contacts stored. If you keep a big list but email it sparingly, that single difference can make Brevo dramatically cheaper than the contact-metered tools. It also bundles transactional email and SMS, which most rivals treat as separate products.
- Best for: businesses with large lists and modest sending volume, or anyone who wants marketing and transactional email under one roof.
- Pricing model: send-volume based rather than contact-based, with a usable free tier capped by daily sends.
- Watch out: the interface and template editor feel a step behind the polish of Mailchimp or MailerLite, and some advanced features gate behind higher plans.
7. MailerLite
MailerLite is the value pick: a genuinely generous free tier, clean modern editor, solid automation for the price, and landing pages included. It has quietly become the tool people move to when they hit the Mailchimp ceiling and discover the same essentials cost less elsewhere.
- Best for: budget-conscious small businesses that want modern essentials — clean emails, basic automation, landing pages — at the lowest sticker price.
- Pricing model: subscriber-tiered, priced consistently below the big names, with a real free tier.
- Watch out: it's still a contact meter, just a gentler one — the bill still grows with the list. Approval to start sending involves a review process that can trip up brand-new domains, and advanced automation is thinner than the specialists.
8. Klaviyo
Klaviyo owns e-commerce email. Its integrations with store platforms are deep rather than decorative — purchase history, browse behavior, and predicted lifetime value flow straight into segments and flows, and the pre-built abandoned-cart and post-purchase sequences are the category standard. If you run an online store at volume, Klaviyo is the specialist to beat.
- Best for: e-commerce stores where revenue-per-email is the metric and behavioral data drives the sends.
- Pricing model: contact-tiered and priced at a premium — among the steepest meters in the category as lists grow.
- Watch out: the cost curve. Klaviyo's pricing is famously aggressive at scale, and outside e-commerce its advantages mostly evaporate. A newsletter business has no reason to pay Klaviyo rates.
9. Moosend
Moosend is the quiet budget contender: a capable drag-and-drop editor, real automation workflows, and pricing that undercuts nearly everyone at comparable list sizes. It gets recommended less because it markets less, not because it does less.
- Best for: price-sensitive senders who want automation and a decent editor without the big-brand markup.
- Pricing model: subscriber-tiered at low price points; paid plans start cheap and stay comparatively cheap.
- Watch out: the ecosystem is thinner — fewer native integrations, a smaller template library, and less third-party documentation when you get stuck.
How to choose.
- Price the list you'll have, not the list you have. Take a realistic twelve-month subscriber goal and look up that tier on each vendor's pricing page. This single step reorders the list for most businesses — and it's the whole argument for flat-fee and send-based models.
- Match the specialist to your actual motion. E-commerce at volume? Klaviyo. Automation-driven funnel? ActiveCampaign. Creator monetizing an audience? Kit. Newsletter on a budget? MailerLite or Moosend. Big list, light sending? Brevo.
- Count the tools around the email tool. Your list lives next to a CRM, a store, and a website. If each is a separate subscription with a separate sync, consider whether an all-in-one platform — where email is one module among 50+ — fits better than a specialist plus satellites. The same logic applies to choosing a CRM.
FAQ
What is the best email marketing software for a small business?
It depends on your motion: Mewayz if you want email inside a flat-fee platform with your CRM, store, and website — with no per-contact meter; Mailchimp for the easiest start; ActiveCampaign for serious automation; Klaviyo for e-commerce; Kit for creators; MailerLite or Moosend for the best price on the essentials; Brevo if you have a big list but send lightly.
How much does email marketing software cost?
Most tools charge by contact count across feature tiers, so the real cost is your list size in a year, not the entry price today. Brevo meters sends instead of contacts, which suits large quiet lists. Mewayz charges one flat fee for the whole platform, email included, with no per-contact charges.
What is the "Mailchimp ceiling"?
Our name for the moment a contact-metered bill outgrows the tool's value: your list grows, the tier steps up automatically, and you find yourself deleting subscribers to lower the bill. It's not unique to Mailchimp — it's the category's default pricing model — but Mailchimp made it famous.
Does email deliverability depend on the tool I choose?
Less than vendors imply. Reputable platforms all maintain solid sending infrastructure; what actually decides inbox placement is mostly yours to control — domain authentication (SPF, DKIM, DMARC), list quality, opt-in practices, and consistent sending. A well-run list on a cheap tool out-delivers a bought list on an expensive one, every time.
Is free email marketing software good enough?
To start, often yes — MailerLite and Brevo have genuinely usable free tiers, and Mailchimp's works for small lists. But free tiers are acquisition funnels: the features and volume you'll need within months sit past the paywall, and by then migrating feels expensive. Decide based on the paid tier you'll actually need, not the free one you'll start on.
The bottom line.
Don't pick email software off a feature grid — every tool here can build a decent campaign. Pick based on what the bill does when your list doubles, and whether the boring deliverability basics are easy to get right. If the answer you want is "the list grows and the bill doesn't," that's the model we built: email marketing as one module of 50+ on one flat fee, next to your CRM, store, and site. Start free, look around, and hold our email module to the same standard we held everyone else to above.
