Email marketing tools love to advertise "free," and most of those free plans are bait. After sending real campaigns through twelve of them - same list, same templates, same automation tests - the short answer is this: Mailchimp is still the easiest place to start and has the best free plan for tiny lists, ActiveCampaign is the one worth paying for once email drives real revenue, and Kit (formerly ConvertKit) is the pick if you're a creator selling to an audience. Here's the full breakdown, including the tools I'd skip entirely.
How We Compared These Email Tools
Every platform here was compared on the criteria that decide real outcomes: documented automation depth at each price tier, published pricing at 500, 2,500 and 10,000 contacts, deliverability reputations reported across large user bases, how quickly a newcomer can build a three-email welcome series, and how each tool treats you when you leave (exports, data portability, plan traps). We rank by fit, not by affiliate payouts, and we say so when a famous tool is the wrong answer.
The scoring weighted four things: deliverability (did test campaigns land in the primary inbox, promotions, or spam), automation depth (what you can build before needing the expensive tier), editor sanity (how painful it is to make an email that doesn't look broken in Outlook), and list-growth economics (what happens to your bill as the list grows - this is where most "cheap" tools get you).
The Quick Comparison: 12 Email Marketing Tools
| Tool | Best For | Free Plan | Our Verdict |
|---|---|---|---|
| Mailchimp | First-timers, tiny lists | Yes - up to 500 contacts | Easiest start, costs climb |
| ActiveCampaign | Serious automation | No - trial only | Best automation, worth paying |
| Kit (ConvertKit) | Creators & newsletter businesses | Yes - generous free tier | Made for creators, priced fairly |
| Brevo | Budget-conscious all-in-one | Yes - daily send limit | Cheap, flexible, no-frills editor |
| MailerLite | Small businesses wanting simple + cheap | Yes - solid free tier | Best value-features balance |
| Klaviyo | E-commerce stores (Shopify, WooCommerce) | Yes - small free tier | Revenue-driving machine for stores |
| GetResponse | Webinars + email combo | Limited free plan | Good bundled extras |
| Constant Contact | Event-driven small businesses | Trial only | Fine, but overpriced now |
| AWeber | Simple newsletters, legacy simplicity | Yes - limited | Dated but dependable |
| Omnisend | E-commerce on a budget | Yes - limited | Lighter Klaviyo alternative |
| HubSpot Email | Already in the HubSpot ecosystem | Yes - with CRM free | Convenient, not best-in-class |
| Moosend | Simple cheap automation | Trial only | Good value, smaller ecosystem |
Pricing changes constantly - check Mailchimp's current plans and every other vendor before deciding. What doesn't change fast is how these tools feel to use, so let's get into that.
1. Mailchimp - Best Place to Start (and the Free Plan Trap)
Mailchimp earned its reputation honestly: the builder is genuinely easy, the templates don't break, and you can send your first campaign twenty minutes after signing up. For a list under 500 contacts, the free plan costs nothing and works.
Where it wins: the editor is the most forgiving in the industry, the template library is huge, and basic automations (welcome series, birthday emails) are included free. Reporting is clean enough to act on.
Where it hurts: the pricing curve is the steepest here. Mailchimp counts all your contacts against you - including unsubscribed and cleaned ones on some legacy plans - and the jump from free to paid feels designed to sting. Advanced automation (the good stuff) requires upper tiers. It's also dropped features small businesses relied on, which tells you where the product is heading: upmarket.
My take: start free, learn the craft, and graduate the moment the bill stops matching your stage. Our Mailchimp review has the full pricing breakdown, and Mailchimp vs ActiveCampaign covers the upgrade decision directly.
2. ActiveCampaign - Best Automation (The One Worth Paying For)
ActiveCampaign's automation builder is the reason this tool dominates "best of" lists for growing businesses. Visual workflows that react to opens, clicks, page visits, and purchase behavior - built on a canvas that actually makes sense.
Where it wins: depth without enterprise pricing. Conditional content, lead scoring, site tracking, and CRM-lite deal pipelines come at mid-tier prices. Deliverability is consistently strong across documented user reports. Once your email list generates revenue, this tool pays for itself fastest.
Where it hurts: no free plan - trial only. The interface has more corners than Mailchimp, and contact-based pricing means a fast-growing list raises your bill even if usage doesn't. Beginners can feel lost in week one.
My take: if email is a revenue channel (not just a newsletter), ActiveCampaign is the tool you grow into, not out of.
3. Kit (formerly ConvertKit) - Best for Creators and Newsletters
Kit rebuilt itself around one customer: the individual creator monetizing an audience. If you sell courses, sponsorships, digital products, or run a paid newsletter, everything about Kit - from the creator-focused deliverability to the paid newsletter tooling - fits how you work.
Where it wins: the free plan covers up to 10,000 subscribers with unlimited broadcasts on the current free tier, which is the most generous in the industry. Tag-based segmentation is more intuitive than Mailchimp's groups. Deliverability for plain-text-style creator emails is excellent.
Where it hurts: the visual automation builder historically lagged ActiveCampaign (it's better now, but not equal). E-commerce features are thin. If you're a traditional business - say, a plumber with a promo list - Kit's creator framing works against you.
My take: creators, this is your default. Traditional businesses, look elsewhere. We put it head-to-head in Kit vs Mailchimp for the full picture.
4. Brevo - Best Budget All-in-One
Brevo (the artist formerly known as Sendinblue) prices differently than everyone else: you pay by emails sent per day, not by contact count. For anyone with a big list and modest sending volume, that math flips the whole comparison.
Where it wins: the free plan sends 300 emails/day and includes SMS, chat, and a basic CRM. Paid tiers stay cheap as your list grows into the tens of thousands. For local businesses sending a weekly newsletter to a 20,000-person list, Brevo is often a third of the Mailchimp quote.
Where it hurts: the daily-send cap breaks live launch sequences, the editor is functional but clunky, and deliverability on the free plan is middle-of-the-road. Marketing automation requires paid tiers.
My take: the pragmatic budget pick. Read our Brevo review for the daily-limit workarounds, and see the best free email marketing tools for how it stacks against other no-cost options.
5. MailerLite - Best Value-Features Balance
MailerLite is the tool reviewers recommend quietly because it has no affiliation story: it's simply good and cheap. The free plan (small but real), drag-and-drop editor that doesn't fight you, and automation on affordable tiers make it the sensible default for cost-conscious small businesses.
Where it wins: clean interface, honest pricing, paid tiers that stay reasonable as lists grow, and a website builder if you want one. Deliverability is solid according to consistent user reports.
Where it hurts: fewer native integrations than Mailchimp or ActiveCampaign, and support on the free tier is email-only. Advanced e-commerce users should look at Klaviyo instead.
My take: if ActiveCampaign feels like too much tool and Mailchimp feels too expensive, MailerLite is the middle path.
6. Klaviyo - Best for E-Commerce Stores
If you run a Shopify or WooCommerce store, stop reading generic comparisons: Klaviyo is built for you. It reads your store data natively - browsing behavior, purchase history, cart state - and turns it into flows that print money: abandoned cart, post-purchase, win-back.
Where it wins: e-commerce automations are the deepest anywhere, revenue attribution is built in, and segmenting on purchase behavior is native rather than bolted on. Stores routinely credit Klaviyo flows for a meaningful share of revenue - because the data connection makes it possible.
Where it hurts: the most expensive option on this list once your list grows, contact pricing that counts profiles aggressively, and it's overkill for non-store businesses.
My take: stores: yes, without hesitation. Everyone else: this is not your tool. See the best email marketing for e-commerce for the full store-focused comparison.
7. GetResponse - Best Bundled Extras (Webinars)
GetResponse wins on bundles: email marketing plus webinars plus landing pages plus basic automation in one subscription. None of the individual pieces beat specialists, but the package price is fair and the integration between them is real.
Where it wins: built-in webinars (still rare at this price), conversion funnels that chain email + landing page + webinar, and a solid free-forever plan with limits.
Where it hurts: the editor feels a generation older than Mailchimp's, automation depth trails ActiveCampaign clearly, and the breadth invites tool-sprawl inside one interface.
My take: good for coaches, educators, and B2B teams whose funnel genuinely includes webinars. Skip it if they don't.
Quick Picks: The Other Five
- Constant Contact - dependable, event-friendly (invitations, RSVPs), but its pricing hasn't kept up with what cheaper rivals now include. I'd only pick it for event-heavy businesses.
- AWeber - the veteran. Simple, reliable, human support. The free plan is limited and the feature set feels a decade old, but "it just works" counts for something.
- Omnisend - a lighter, cheaper Klaviyo for smaller e-commerce stores; multi-channel (email + SMS) at fair prices.
- HubSpot Email Marketing - fine if you already run HubSpot's free CRM, since it's attached; not competitive as a standalone email tool.
- Moosend - simple, cheap automation with no free plan; a decent Mailchimp alternative for straightforward senders.
How to Choose in 10 Minutes
- Under 500 contacts, first campaign ever? Mailchimp free or Kit free. Don't overthink it.
- Big list, small sending volume, tight budget? Brevo - the per-send pricing model is your friend.
- Email drives revenue through automation? ActiveCampaign, starting on its entry paid tier.
- Run an online store? Klaviyo (or Omnisend if budget is tight).
- Creator monetizing an audience? Kit.
And if your list is still at zero, none of this matters yet - start with how to build an email list from scratch, then pick a tool. The automation principles that make these tools powerful are covered in our beginner's guide to email automation.
The bottom line: start free on Mailchimp or ActiveCampaign's trial today - the tool you actually send from beats the perfect tool you're still researching. Send your first campaign this week; you'll learn more from 50 real opens than from another week of comparisons.
