Email is still the highest-ROI channel in marketing — the list you own beats the algorithm you rent, every year, in every study we can find. But the platform market has splintered into specialists: tools built for creators, tools built for stores, tools built for people who send twice a year and refuse to pay monthly. Picking the “best” email marketing platform without naming the use case is how people end up paying Klaviyo prices for a newsletter or fighting Mailchimp’s automation builder to do creator work it was never designed for. So this guide ranks six platforms we have spent real time inside — imported lists, built automations, sent campaigns, read the deliverability headers — and names exactly who each one is for.
How we ranked: We weighted four things. Deliverability first, because a beautiful email in the spam folder is worth nothing — we sent seed-list tests and checked inbox placement across Gmail, Outlook and Yahoo. Then pricing honesty: what the bill looks like at 1,000, 10,000 and 50,000 subscribers, including the features that quietly move to higher tiers. Then automation depth relative to the audience each tool targets. And finally the unquantifiable one — how fast a normal person can get a good-looking campaign out the door. Positions reflect fit for the named use case, not a single leaderboard; the best platform for a Shopify store is a bad buy for a newsletter writer.
1. Kit — best for creators
Kit (formerly ConvertKit) is what happens when a platform picks one customer — the creator — and refuses to be distracted. The email editor is deliberately plain because creators send text-first emails that look personal, and Kit’s deliverability reputation is built partly on that discipline. The subscriber model is tag-based rather than list-based, so one human is one contact no matter how many ways you slice them, which keeps both your data and your bill clean. The visual automation builder is the best in this class: readable enough that you can debug a launch funnel at a glance. Add the creator-economy extras — a landing page builder, paid newsletter and digital product sales with built-in payments, and a creator network that drives real referral growth — and the pitch is complete. Pricing scales by subscriber count with a workable free tier for small lists. Our full Kit review digs into the details, but the short version stands: if you sell audience attention for a living, start here.
2. Brevo — best pay-per-send value
Brevo (formerly Sendinblue) breaks the industry’s favorite pricing trick. Almost everyone bills by list size, which means you pay every month for subscribers you did not email. Brevo bills by emails sent — store 100,000 contacts free, pay only when you hit send. For anyone with a big list and a modest sending rhythm — a monthly newsletter, a seasonal business, a nonprofit — the math is not close: we have seen bills drop by two-thirds in like-for-like migrations. The platform itself is broader than the price suggests: solid drag-and-drop editor, SMS and WhatsApp campaigns, transactional email via SMTP and API, a lightweight CRM, and automation journeys that cover the standard welcome, cart and re-engagement patterns. The trade-offs are real but livable — the template gallery is smaller than Mailchimp’s and the reporting is more functional than beautiful. Our Brevo review runs the full numbers. If your list is large and your cadence is light, this is the value pick of the entire market.
3. GetResponse — best all-in-one with webinars
GetResponse’s claim to a slot on this list is a feature nobody else here has: native webinars. If your funnel runs on live teaching — course creators, coaches, B2B demand gen — hosting webinars inside the same tool that runs your email list eliminates a Zoom-plus-Zapier contraption and keeps registration, reminders, attendance data and follow-up sequences in one place. Around that centerpiece sits a genuinely complete suite: a capable email editor, conversion funnels with templates for common launch patterns, landing pages, a website builder, and automation with scoring and event-based triggers that goes deeper than most mid-market rivals. Deliverability held up well in our seed tests, and the pricing sits in the reasonable middle of the market with meaningful discounts on longer commitments. The honest caveat is focus: no single module is the absolute best in its category — Kit’s automations read more cleanly, Brevo’s pricing is friendlier. But as one subscription replacing four, it is compelling; our GetResponse review covers the whole suite.
4. Mailchimp — best template ecosystem
Mailchimp remains the default name in email for a reason: nothing matches the maturity of its ecosystem. The template gallery is the largest and most polished in the industry, the drag-and-drop editor is friendly to complete beginners, and the integration directory connects to effectively everything — every form builder, every commerce platform, every CRM has a Mailchimp integration before any other. The reporting and audience insights are genuinely strong, and the AI-assisted content and creative tools have improved quickly. So why fourth? Pricing. Mailchimp bills by contact — including, notoriously, unsubscribed contacts unless you archive them — and the features that matter (advanced automation journeys, better support, send-time optimization) climb the tier ladder fast. Costs at 10,000+ subscribers routinely double what Kit or Brevo charge for equivalent work. The free tier that made the brand is now thin. Choose Mailchimp when polish, templates and integrations are worth a premium; audit the bill honestly at your real list size first.
5. MailerLite — best free tier simplicity
MailerLite is the platform we recommend to people who ask, “can this just be easy?” The free tier is the most generous of any serious platform — up to 1,000 subscribers and 12,000 monthly emails with automation, landing pages and signup forms actually included, not dangled. The paid tiers stay cheap as you grow. What makes it more than a budget pick is the editing experience: the cleanest, least cluttered campaign builder on this list, with modern templates and none of the legacy menu sprawl that makes older platforms feel like tax software. Automation covers the essential flows — welcome series, tagged-interest sequences, basic e-commerce triggers — without pretending to be an enterprise journey engine. Deliverability in our tests was solid, helped by strict list-quality enforcement at signup (they review accounts, which keeps spammers off shared IPs). The limits are honest ones: no deep behavioral segmentation, light reporting, few native integrations compared with Mailchimp. For solo operators, side projects and small nonprofits, it is the calmest choice available.
6. Klaviyo — best for e-commerce
If you run an online store, Klaviyo is not really competing with the other names on this list — it is competing with hiring an email marketer. The platform ingests your full commerce data stream (Shopify most natively, plus WooCommerce, BigCommerce and others) and turns it into revenue automations: abandoned cart, browse abandonment, post-purchase upsell, winback, replenishment reminders timed to product lifecycles. Segmentation runs on actual purchase behavior — customers who bought X twice but not Y, spent over a threshold, clicked but never purchased — and the predictive analytics estimate lifetime value and churn risk per customer. Flows attribute revenue directly, so you can see exactly what each automation earns, which makes the notoriously premium pricing self-justifying for stores doing real volume: the platform typically pays for itself several times over. For anyone who is not a store, that pricing is simply too much tool. But for e-commerce, nothing else on this list is close, and most Shopify agencies treat it as the default.
The six platforms at a glance
| Platform | Best for | Typical entry price | Watch out for |
|---|---|---|---|
| Kit | Creators & newsletters | Free tier; paid from ~$25/mo | Plain templates by design |
| Brevo | Big lists, light sending | Free tier; paid from ~$9–25/mo | Smaller template gallery |
| GetResponse | All-in-one with webinars | ~$15–19/mo entry | Jack of all trades, master of none |
| Mailchimp | Templates & integrations | Free tier; paid from ~$13–20/mo | Costs climb fast; billed for unsubscribes |
| MailerLite | Simplicity & free tier | Free to 1,000 subs; paid from ~$9–10/mo | Light reporting and segmentation |
| Klaviyo | E-commerce stores | Free tier; scales steeply with contacts | Expensive for non-stores |
Watch: Choosing the right email marketing platform
How pricing models actually differ
There are three billing philosophies in this market, and matching yours to your sending behavior matters more than any feature comparison. Per-subscriber pricing (Kit, Mailchimp, MailerLite, Klaviyo) charges for the size of your list whether you email it or not — it rewards clean lists and punishes hoarding, and it gets expensive quietly, because lists only grow. Per-send pricing (Brevo) charges for volume actually sent — it rewards big lists with light cadence and punishes daily senders. Flat or bundled pricing (GetResponse’s tiers, roughly) sells you a bucket of capability and stops metering your anxiety.
The practical test: estimate your subscribers a year from now and your realistic monthly send volume, then price all three models at those numbers. A 20,000-contact list emailed monthly costs a fraction on Brevo of what it costs on Mailchimp. A 2,000-contact list emailed three times a week barely notices the difference. And e-commerce flows are their own economy — Klaviyo costs more than everything else here and still wins on net revenue for stores. Run the math at next year’s numbers, not today’s; migrations are annoying enough that you want a platform you can stay with.
Deliverability: the invisible ranking factor
Every platform on this list can land email in an inbox. Whether yours does depends mostly on inputs you control — but the platform’s contribution is real and uneven. Shared IP pools mean you inherit your neighbors’ reputation, so platforms that police signups aggressively (MailerLite, Kit) tend to keep cleaner pools than platforms with enormous free tiers historically open to anyone. Authentication is the other platform-side factor: since Gmail and Yahoo tightened bulk-sender rules in 2024, proper SPF, DKIM and DMARC alignment on your own domain went from best practice to requirement, and the better platforms now walk you through it at setup rather than burying it in a help doc.
Your side of the bargain is list hygiene and engagement. Never buy lists. Use double opt-in when your growth can afford the friction. Prune subscribers who have not opened in six months — per-subscriber pricing makes this financially virtuous, deliverability makes it strategically virtuous, and the pruned rarely notice. Watch your engagement rates by mailbox provider: a sudden Gmail-only open-rate collapse is the classic sign you have been demoted to the Promotions tab or worse. No platform can rescue a list that stopped wanting your email; every platform can quietly amplify one that does.
Common buying mistakes
The mistakes we see repeat with depressing regularity. Choosing by template beauty — the email your subscriber sees for 4 seconds matters less than the automation that decided when to send it. Ignoring the price at 10x your current list size, then facing a migration right when the newsletter finally works. Paying for automation depth you will never build — most senders use a welcome series and a broadcast, and that is fine. Keeping unsubscribed and dead contacts on per-subscriber billing out of digital hoarding. And skipping the free trial’s real test: import your actual list, build your actual welcome flow, and send an actual campaign before the card gets charged. An afternoon of honest testing beats a month of comparison-table reading.
Which should you pick?
Map yourself to a row. Creator or newsletter writer selling attention or products: Kit, without much deliberation. Large list, modest sending schedule, budget-conscious: Brevo. Funnel built on webinars and launches: GetResponse. Beginner who values polish and plugs into a dozen other tools: Mailchimp, with eyes open on pricing. Solo operator who wants calm software and a real free tier: MailerLite. Online store with meaningful volume: Klaviyo, and stop reading comparison articles — the ROI case closes itself. If you are genuinely torn between two, run both free tiers for a week with your real list; the platform that gets a campaign out the door with less friction is the right answer for you.
Email platform deals
Most platforms on this list discount 15–30% for annual billing, and several run seasonal promotions — Black Friday reliably brings the deepest cuts, and GetResponse and Brevo discount aggressively through the year. Free tiers make trials risk-free regardless. We track current working offers on our deals page as they appear.
Frequently asked questions
What is the best free email marketing platform? MailerLite’s free tier is the most generous serious option — 1,000 subscribers and 12,000 emails a month with automation included. Brevo’s free tier is best if your list is bigger but you send lightly.
Is Mailchimp still worth it? Yes for beginners who value templates and integrations above all, but audit the pricing at your real list size — including unsubscribed contacts — before committing. Alternatives now beat it on cost at almost every scale.
Which platform has the best deliverability? Deliverability is mostly determined by your list quality and domain authentication, but platforms that police their shared IP pools — Kit and MailerLite notably — give you a cleaner starting position.
Do I need Klaviyo if I run a small store? Not immediately. Under a few hundred orders a month, Brevo or Mailchimp’s commerce features cover the basics. Klaviyo’s pricing earns itself once abandoned-cart and winback flows have real volume to work with.
Can I switch platforms later? Yes — subscriber lists export and import cleanly everywhere. What does not transfer is automation history, engagement data and template builds, so switching costs a weekend, not just a CSV. Choose for next year’s list size to avoid it.
What is the difference between per-subscriber and per-send pricing? Per-subscriber (Kit, Mailchimp, Klaviyo) bills your list size monthly regardless of activity. Per-send (Brevo) bills email volume. Big list plus light cadence favors per-send; small list plus heavy cadence favors per-subscriber.
Are the AI features worth paying extra for? Subject-line suggestions and send-time optimization are nice-to-haves that occasionally pay off; none justify a tier upgrade on their own. Automation depth and deliverability should still drive the decision.
How to choose an email marketing platform: a practical guide
Start by naming your sender type honestly — creator, store, newsletter, nonprofit, B2B funnel — because that single answer eliminates most of the market and the “best overall” framing that sells comparison articles serves nobody’s actual bill. Then project your list size and sending cadence twelve months out and price the three billing models at those numbers; the cheapest platform today is frequently the most expensive one at the size you are trying to reach. Third, list the three automations you will genuinely run — for most senders that is a welcome series, a broadcast rhythm and one behavioral flow — and verify each candidate does those three well instead of admiring journey builders you will never open. Fourth, check the deliverability fundamentals: does the platform enforce list quality, walk you through SPF, DKIM and DMARC on your own domain, and publish honest guidance rather than blaming you in the help docs? Fifth, test the actual workflow with your actual content during the free tier or trial, because friction you feel in week one compounds weekly forever. And finally, weigh the exit: lists move easily, automations do not, so favor the platform you can imagine still using when the list is ten times the size. That lens is exactly why Kit tops this list for creators, Brevo for value, and Klaviyo for stores — different winners, one honest method.
