Editor's Pick

Mailchimp

The default email marketing platform for small businesses for a reason

Mailchimp's free tier covers up to 500 contacts and 1,000 emails per month — genuinely useful for businesses just starting out. The drag-and-drop builder is the most polished in the category, the template library is broad, and integrations with Shopify, Square, QuickBooks, and Canva work out of the box. Best general-purpose choice for SMBs with under 25 employees.

Constant Contact

Easiest email platform for non-technical small business owners

Constant Contact's interface is the simplest in the category — designed for restaurant owners, real estate agents, and retail shop owners who don't have time to learn complex software. Includes event marketing tools, SMS marketing, and Eventbrite integration. US-based phone support sets it apart from purely DIY platforms.

HubSpot Email Marketing

Best free email tool with built-in CRM integration

HubSpot's free email marketing is genuinely free — 2,000 sends per month with the free CRM included. The Starter plan ($20/mo) unlocks automation, A/B testing, and removes HubSpot branding. The killer feature for SMBs: email behavior automatically syncs with the free CRM, so you can see exactly which contacts opened, clicked, and engaged.

Brevo (formerly Sendinblue)

Most generous free tier — 300 emails per day with unlimited contacts

Brevo's free plan is uniquely generous: 300 emails per day with no contact list cap. That makes it the natural choice for SMBs with growing lists but limited budgets. Includes email, SMS, WhatsApp marketing, transactional email, and basic CRM in one platform. European-based, which means strong GDPR compliance out of the box.

MailerLite

Cleanest interface in the category for solopreneurs and creators

MailerLite has built a reputation as the best-designed email tool for creators, bloggers, and solopreneurs. The free tier covers 1,000 subscribers and 12,000 sends per month. Drag-and-drop builder is intuitive, automation is more flexible than Mailchimp's free tier, and the platform handles segmentation and personalization well at an affordable price.

ActiveCampaign

Deepest automation features for growth-stage SMBs

ActiveCampaign's automation builder is the most flexible in the SMB category, with conditional logic, lead scoring, site tracking, and tight CRM integration.

Klaviyo

The clear winner for small eCommerce businesses on Shopify

Klaviyo dominates eCommerce email for small brands on Shopify, BigCommerce, and WooCommerce. Pre-built flows for abandoned cart, browse abandonment, post-purchase, win-back, and back-in-stock are far more sophisticated than general-purpose platforms. Pricing scales by contact volume, so it gets expensive fast — but the revenue lift justifies it for product businesses.

Omnisend

Klaviyo alternative for smaller eCommerce stores with simpler needs

Omnisend competes directly with Klaviyo for smaller eCommerce stores, with a friendlier interface and lower pricing at low contact volumes. Pre-built workflow templates handle the major eCommerce email flows out of the box. Native integrations with Shopify, BigCommerce, WooCommerce, Wix, and Squarespace. Best for stores under $1M in revenue.

Kit (renamed from ConvertKit in 2024) is built specifically for content creators, course creators, podcasters, and digital product sellers. Tag-based subscriber management, visual automation builder, and built-in commerce for selling digital products. Less suited for traditional small businesses, but the standout choice for solo creators monetizing an audience.

FAQ

Common questions

What's the best free email marketing platform for small business?
For most SMBs, HubSpot's free tier is the strongest choice — 2,000 sends per month with a free CRM included is hard to beat. Mailchimp's free tier (500 contacts, 1,000 sends) is the simplest. Brevo's 300 emails per day with unlimited contacts is best for businesses with large but inactive lists. MailerLite's free tier (1,000 subscribers, 12,000 sends) is the most generous for solopreneurs.
Mailchimp vs Constant Contact — which is better for small business?
Mailchimp wins on design flexibility, integrations, and overall product depth. Constant Contact wins on ease of use, US-based phone support, and event marketing features. Mailchimp is better if you have some technical comfort. Constant Contact is better if you want to call someone for help. For pure pricing, Mailchimp's free tier beats Constant Contact's 60-day trial.
How much should a small business spend on email marketing software?
For SMBs with under 5,000 contacts, expect $15-50 per month. Once you cross 10,000 contacts, expect $50-150 per month. eCommerce businesses on Klaviyo or Omnisend typically spend more because pricing scales with contact volume — but the revenue from email usually 10-20x covers the cost. As a rule of thumb, email marketing software should cost no more than 5-10% of your total marketing budget.
Which email platform has the best deliverability?
Independent testing from EmailToolTester and similar services typically puts ActiveCampaign, MailerLite, and Klaviyo at the top for deliverability. Mailchimp and Constant Contact perform well but slightly behind. Deliverability matters more than raw price — landing in spam folders defeats the purpose, regardless of how cheap the platform is.
Do these platforms integrate with QuickBooks, Shopify, and Square?
All 10 platforms have direct Shopify integrations. For QuickBooks integration, HubSpot, Mailchimp, Constant Contact, and ActiveCampaign have native connections. Square integrates natively with Mailchimp and Constant Contact, and via Zapier with most others. Always verify the specific integration depth — some are deeper than others.
Is sponsored placement allowed in these rankings?
Top-tier editorial placements are never sold. Products can claim and customize their profile, or upgrade to an Enhanced or Featured listing for premium visibility — but ranking order is determined by the methodology above. Sponsored placements are always clearly labeled.
