Prices reflect entry-level paid plans at time of writing. Use this table as a shortcut before diving into the breakdown.

1. Mailchimp

Best for: Small businesses that want email marketing software with a light CRM and landing pages without extra bolt-ons.

Mailchimp combines a drag-and-drop builder, pre-built automations, and a free tier for up to 500 contacts. The Creative Assistant uses AI to generate on-brand designs quickly, which saves time if you lack design resources. Just know that pricing jumps sharply once you outgrow the free plan. Mobile apps let you manage campaigns and view reports on the go, and the built-in CRM keeps basic contact records tidy without a separate tool.

2. Constant Contact

Best for: Traditional small businesses that run events and want phone support without paying a premium.

Constant Contact offers a straightforward editor, a massive template library, and built-in event management with RSVP tracking and ticket sales. Those event tools set it apart: you can promote, collect registrations, and follow up inside one platform. Social posting features are included too, so you’re not hopping between apps. Phone support comes on all plans, which is rare at this price point and useful if you prefer a human when something breaks.

3. ActiveCampaign

Best for: Businesses that need deep marketing automation and a CRM in one place, and are willing to climb a learning curve.

ActiveCampaign ties email sequences, site tracking, and lead scoring into a single flow. The visual automation builder uses real “if this, then that” logic, so you can trigger actions based on page visits, link clicks, or deal stage changes. It’s the only tool here that also manages a full sales pipeline alongside email. Expect a steeper setup and pricing that scales with both contact count and the features you unlock.

4. Brevo

Best for: Teams that want email, SMS, and transactional messages without per-contact pricing traps.

Brevo charges by email volume, not contact count, so you can keep unlimited contacts even on the free tier. The built-in CRM and transactional email deliverability make it a solid all-in-one pick. You can run multi-channel campaigns with WhatsApp and SMS under the same dashboard. Just note that advanced segmentation and reporting are locked behind the higher-tier Business plan, so budget for that step-up if your targeting needs grow.

5. Klaviyo

Best for: E-commerce stores — especially on Shopify — that treat email as a revenue channel, not a cost center.

Klaviyo pulls real-time browse, cart, and purchase data to build hyper-personalized flows. Pre-built automations for abandoned cart, back-in-stock, and win-back sequences turn insights into revenue fast, often with minimal tweaking. Pricing is based on contact count and escalates quickly, but stores seeing direct ROI usually accept the trade-off. If your business doesn’t live inside a shopping cart, the deep e-commerce focus can feel over-engineered.

6. Kit

Best for: Creators, bloggers, and paid newsletter writers who want monetization built in.

Kit uses a visual automation builder and a tagging-based subscriber system instead of traditional lists, which keeps segmentation clean for content-driven audiences. The native Creator Network and tools for selling digital products or paid subscriptions mean you don’t need extra apps to earn from your list. The free plan supports unlimited landing pages and forms, but automations are only active on paid plans. That’s a real limit if automated sequences are central to your workflow.

7. MailerLite

Best for: Solo founders and small teams who want a clean interface and strong automation on a free plan.

MailerLite feels lightweight but not stripped down: you get an intuitive drag-and-drop editor, landing pages, and simple automation workflows. The free tier covers 1,000 subscribers and 12,000 emails per month, which is generous compared to most rivals. Once you move to the paid Starter plan, you also gain a custom HTML editor and dynamic email blocks, which many competitors reserve for pricier tiers. It’s a practical choice when budget is tight but you can’t sacrifice deliverability.

8. GetResponse

Best for: Businesses that want email marketing bundled with a native webinar tool and site builder.

GetResponse packs email autoresponders, a website builder, and conversion funnels into one subscription. The built-in webinar feature is the real differentiator: you can host live sessions, send automated reminders, and nurture leads without patching together third-party integrations. The AI-powered website builder can even replace a standalone site if you’re launching from zero. It’s a lot of tool in one place, so expect a short onboarding period to learn where everything lives.

How we picked these tools

We logged into each administration panel, set up a test list, and ran a campaign where feasible. Our side-by-side comparison focused on ease of setup, deliverability reputation, automation depth, and pricing transparency. We eliminated tools with predatory cancellation flows or free-tier caps that mislead in marketing but throttle real use. Because each pick targets a distinct use case, the strongest tool for you depends entirely on your business type, not a one-size-fits-all badge.

Frequently asked questions

What should I look for in email marketing software?

Non-negotiable features: a drag-and-drop builder, responsive templates, basic automations (welcome and follow-up sequences), clear reporting, and list hygiene tools. Match the software’s complexity to your team’s skill level: a freelancer doesn’t need the same depth as a marketing team running lead scoring.

How much should a small business spend?

Typical free plans cover up to 1,000 contacts. Essentials run $10–$30 per month once you need more volume or automation. Advanced tiers that unlock behavior-based sequences and CRM functions push to $50 or more. Per-contact pricing escalates fast, so prune your list regularly.

Is it easy to switch email platforms later?

Most services support CSV list imports and basic template migration, but automations almost always need rebuilding from scratch. Export your subscriber data, then warm up a new sending domain gradually to protect deliverability during the transition.

Does my CRM need to be built in?

Not necessarily. All-in-one tools give you enough CRM fundamentals to manage contacts and deals without leaving the app. If you already rely on a dedicated CRM like HubSpot or Salesforce, prioritize email tools that offer native integrations rather than replacing what already works.

The verdict

Mailchimp is the strongest single pick for the broadest range of businesses. It balances features, a free tier, and a shallow learning curve better than anyone else. For any e-commerce store serious about revenue from email, Klaviyo is the runner-up worth every dollar. If per-contact pricing in other tools doesn’t add up, Brevo’s volume-based model makes it the smart budget-conscious alternative without cutting essential channels.
