The question asked, verbatim: best email marketing software for small businesses

Brands named, in the order the engine gave

1. MailerLite recommended
   MailerLite - my default recommendation for most small businesses.
2. Brevo mentioned
   Brevo (formerly Sendinblue) - pick this if your list is large relative to how often you mail, or you want SMS/WhatsApp in the same tool.
3. Mailchimp mentioned
   It bills by emails sent, not contacts stored, which is a big deal: a 20,000-contact list that gets one monthly newsletter costs a fraction of what Mailchimp would charge.
4. Klaviyo mentioned
   Klaviyo - the clear answer only if you sell physical products online, especially on Shopify or WooCommerce.
5. Shopify mentioned
   Klaviyo - the clear answer only if you sell physical products online, especially on Shopify or WooCommerce.
6. WooCommerce mentioned
   Klaviyo - the clear answer only if you sell physical products online, especially on Shopify or WooCommerce.
7. Constant Contact mentioned
   Constant Contact - worth a look if you're a local/service business that does events and wants phone support from a human.
8. Sender mentioned
   One more, if budget is the whole question: Sender has the most generous free tier going - roughly 2,500 contacts and 15,000 emails/month with automation included.
9. Zapier mentioned
   The pricing and feature details above come from TechRadar and Zapier's hands-on reviews, but verify current pricing on the vendors' own pages before committing - these companies change tiers often.

The answer, as recorded

## My picks, in order **1. MailerLite** - my default recommendation for most small businesses. It's the best balance of "easy enough to use on a Tuesday afternoon" and genuinely capable automation. Free up to 500 subscribers / 12,000 emails a month, then ~$10/month on the Growing Business plan. Clean drag-and-drop builder with pre-built blocks, landing pages and signup forms included, and no upsell maze. The honest limit: if you need deep CRM or complex multi-branch automation, you'll outgrow it. **2. Brevo** (formerly Sendinblue) - pick this if your list is large relative to how often you mail, or you want SMS/WhatsApp in the same tool. It bills by **emails sent**, not contacts stored, which is a big deal: a 20,000-contact list that gets one monthly newsletter costs a fraction of what Mailchimp would charge. Paid plans start around $9/month, and it includes a free CRM and transactional email (useful if you also send receipts or password resets). **3. Klaviyo** - the clear answer *only* if you sell physical products online, especially on Shopify or WooCommerce. Its product/purchase-data integration drives abandoned-cart, post-purchase and win-back flows that the general-purpose tools approximate at best. Free up to 250 contacts, ~$20/month from there. For a non-ecommerce business it's overkill and overpriced. **4. Mailchimp** - still the safest "everyone knows it" choice, with the widest integration library and an all-in-one dashboard (ads, social, landing pages, SMS). I rank it fourth because its pricing counts contacts aggressively and the free plan is now stingy (250 subscribers, 500 sends/month). Worth it if you want one tool for all channels or your agency/contractor already knows it. **5. Constant Contact** - worth a look if you're a local/service business that does events and wants phone support from a human. Expensive per contact and dated-feeling, but the hand-holding is real. **One more, if budget is the whole question:** **Sender** has the most generous free tier going - roughly 2,500 contacts and 15,000 emails/month *with* automation included. Smaller ecosystem, but hard to argue with free. ## The short version Not ecommerce → **MailerLite**. Big list, infrequent sends, or want SMS → **Brevo**. Selling products online → **Klaviyo**. Want the brand name and every integration → **Mailchimp**. One caveat on the research: a lot of what ranks for this query is low-quality affiliate content with made-up rankings (I discarded several). The pricing and feature details above come from TechRadar and Zapier's hands-on reviews, but verify current pricing on the vendors' own pages before committing - these companies change tiers often.
