We compared the major email marketing tools on list management quality, automation sophistication, deliverability rates, and the learning curve for non-marketers. The right pick depends heavily on whether you're selling products (needs ecommerce triggers) or services (needs behavior-based sequences).

Frequently Asked Questions
What is the best free email marketing tool for small business?
Mailchimp's free plan is the most widely used — it supports up to 500 contacts and 1,000 sends/month, with basic templates and automation. ConvertKit's free plan is better for creators and service businesses, offering unlimited landing pages and up to 1,000 subscribers with no branding on emails. Both are genuinely usable without upgrading.
Mailchimp vs ConvertKit: which is better?
Mailchimp is better for e-commerce businesses, retail brands, and teams that want drag-and-drop email design. ConvertKit is better for content creators, coaches, consultants, and service businesses that rely on email sequences and landing pages. The pricing models differ too: Mailchimp bills by contacts, ConvertKit by subscribers — which matters as your list grows.
What email marketing tool has the best deliverability?
ActiveCampaign and Klaviyo consistently rank highest for deliverability. Both have strong sender reputation infrastructure and list hygiene tools that reduce bounce rates. Mailchimp has had historical deliverability issues with shared IP addresses, though their dedicated IP option (available on paid plans) resolves this. For critical transactional emails, use a separate transactional email service regardless of platform.
How much does email marketing software cost for small business?
Email marketing software ranges from free (Mailchimp up to 500 contacts, ConvertKit up to 1,000) to $15–$100/month for most small businesses. Pricing is almost always based on list size. A 5,000-contact list typically costs $50–$100/month across major platforms. Klaviyo can get expensive at scale but its ecommerce ROI typically justifies the cost.
What is the best email marketing tool for e-commerce?
Klaviyo is the best email marketing tool for e-commerce. Its Shopify and WooCommerce integrations are best-in-class — abandoned cart flows, post-purchase sequences, and revenue-per-email analytics are all built-in. ActiveCampaign is a strong alternative for businesses that also want CRM capabilities alongside email.
Do I need email marketing software or can I use Gmail?
You need email marketing software for anything beyond individual 1-to-1 emails. Gmail bulk-sends violate its terms of service and get accounts banned. More importantly, dedicated email marketing platforms provide unsubscribe management (legally required in most countries), deliverability infrastructure, analytics, and automation sequences — none of which Gmail offers.
