10 Email Marketing Tools Small Businesses Can Start Using Today
From free plans to full automation, here are ten tools for sending newsletters and follow-ups, each checked on its maker's site.
Email is still one of the cheapest ways to reach customers you already have. These ten tools cover the range, from free plans for a small list to heavier automation for online stores.
Free-plan limits change often, so each entry says where its numbers came from. Confirm them on the maker's page before you commit.
1Mailchimp
Combines email, SMS, automations, landing pages and reporting, with 300+ integrations. The free plan is limited to 250 contacts and 500 sends a month, and its pricing page notes price changes with contact tier.
Visit Mailchimp →2Brevo
Zapier's roundup says Brevo mixes marketing and sales tools in one app, with up to 100,000 contacts on the free plan. The catch is a strict cap of 300 emails a day on that plan.
Visit Brevo →3MailerLite
Zapier praises its dynamic content blocks and segmentation. MailerLite's pricing page currently lists a free plan with 250 subscribers and 2,500 emails a month, so check the limits before you sign up.
Visit MailerLite →4Zoho Campaigns
Email, SMS and WhatsApp campaigns from one place, with Zoho's Zia AI for copy help and send-time optimization. Zoho's page lists a forever-free plan for up to 2,000 contacts and 6,000 emails a month and integrations with Zoho CRM, Shopify and Zapier.

Sender's site lists a free plan with 2,500 contacts and 15,000 emails a month and no daily send limit. Zapier calls it the most generous free plan but says the editor feels clunky.
Visit Sender →6Omnisend
Built for e-commerce, with email, SMS and web push plus abandoned-cart and post-purchase flows. It connects to Shopify, WooCommerce and BigCommerce. Zapier notes costs rise quickly as subscribers grow.
Visit Omnisend →7Klaviyo
Klaviyo ties customer data to email, SMS and other channels, with 350+ integrations and an AI agent that builds campaigns from a prompt. A free plan exists, and paid plans scale with contacts and channels.
Visit Klaviyo →8ActiveCampaign
Strong on behavior-driven automations and a built-in CRM, with 1,000+ app integrations and connectors for ChatGPT and Claude. Zapier warns of a learning curve, and prices are quoted by request.
Visit ActiveCampaign →9HubSpot Email Marketing
HubSpot's email tools sit inside Marketing Hub and use CRM data for personalization. A free option has a drag-and-drop editor and AI writing help, while A/B testing and automation need a paid edition.
Visit HubSpot Email Marketing →10AWeber
Includes landing pages, signup forms, prebuilt automations and phone, chat and email support all day. The free plan covers 500 subscribers and 3,000 emails a month with AWeber branding, and prices rise with your list size.

We opened each maker's own site to confirm the product exists and to read its features and plan details, and used Zapier's two email roundups for outside verdicts. Where a maker's page did not show a price we left it out, and where Zapier's free-plan figures differed from the maker's current page we went with the maker. The order is our judgment for a typical small business, not a lab test.
