Best Email Marketing for Small Business — 11 Tools Ranked, Real Pricing
MailerLite costs $25/mo at 2,500 subscribers. Mailchimp Standard charges $60/mo for comparable features — that's 58% more. At 10,000 subs, the gap widens: $73/mo vs $135/mo. We ranked all 11 major email marketing tools by verified pricing (March 2026), independent deliverability test scores, and 14,000+ real user reviews from G2, Capterra, Reddit, and Trustpilot. Here's what actually works for small businesses in 2026.

What to look for
- Total cost at your subscriber count — many tools are cheap at 500 contacts but expensive at 5,000
- Do they charge for unsubscribed contacts? Mailchimp and ActiveCampaign do, MailerLite does not
- How steep is the learning curve? You probably do not have a dedicated marketing person
- Deliverability rates from independent testing — not the platform's own claims
- What happens if you need support? Check Trustpilot ratings for real support experiences
Quick Picks
How They Compare
MailerLite is our top pick for small businesses because it nails the trifecta: affordability ($10/mo at 1,000 contacts), highest independent deliverability scores (89.8%), and the best ease-of-use ratings on G2 and Capterra since 2023. The free plan covers 500 subscribers with automation included. The only downside is a strict account approval process — have a real website ready when you sign up.
Brevo's unlimited-contacts pricing model is uniquely valuable for small businesses with larger lists but moderate sending frequency. Instead of paying per subscriber, you pay per email sent — starting at $9/month for 5,000 emails. A business with 5,000 contacts sending twice a month pays a fraction of what Mailchimp charges. The trade-off: the interface is less polished than MailerLite, and the free plan caps you at 300 emails/day.
GetResponse offers a strong middle ground between MailerLite's simplicity and ActiveCampaign's power. At $19/month for 1,000 contacts, you get email marketing, landing pages, webinars, and decent automation. It's particularly good for small businesses that run webinars or need built-in landing pages without paying for a separate tool. Deliverability sits at ~85.5% — solid but not market-leading.
Kit (ConvertKit) is the creator-focused option. If your small business is content-driven — a blog, online courses, a newsletter — Kit's tag-based subscriber management and clean email editor are excellent. The free plan covers 10,000 subscribers (the most generous limit of any platform), but automation is limited to 1 sequence until you pay $33/month.
Mailchimp still has the largest integration ecosystem (300+ apps) and the most recognizable brand. If you rely on niche tools that only connect to Mailchimp, or your team already knows the platform, there is a case for staying. But the pricing premium (36-63% more than MailerLite at every tier), middling deliverability (78.35% inbox placement), and charging for unsubscribed contacts make it a hard sell for cost-conscious small businesses.
