- Brevo is the cheapest paid start at $9/month, Mailchimp is the safest all-rounder from $13/month, and MailerLite is the simplest at $12/month — all three have free plans.

Request a listingThe best email marketing platforms for startups
Mailchimp
Best for: Startup founders who want the best-known all-rounder with the widest integration library
Mailchimp is the default recommendation for a reason: almost every tool a startup uses already connects to it, and the Essentials plan covers the basics — A/B testing, scheduling, simple automation flows and 300-plus integrations — for $13 a month at 500 contacts. The editor is polished, the template library is deep, and the free plan lets a brand-new list get started without a card.
The catch is the pricing curve. Essentials climbs to about $75 a month at 5,000 contacts, and unsubscribed contacts keep counting toward your bill until you archive them. The free plan also shrank in 2026 to 250 contacts and 500 sends a month, so it only fits a very small list. Pick Mailchimp when you want the safest, most connected choice and expect to pay for the convenience as you grow.
What we like
- Largest integration library in this list — 300+ integrations, including Shopify, WordPress and HubSpot
- Essentials includes A/B testing, scheduling and simple automation flows from $13 a month
- Standard adds multi-step automation, predictive segmentation and a 14-day free trial
Watch out for
- Free plan shrank in 2026 to 250 contacts and 500 sends a month, with no automation
- Price climbs steeply with list size — Essentials is about $75 a month at 5,000 contacts
- Unsubscribed contacts count toward your bill until you archive them
Brevo
Best for: Cash-conscious startups that email a large list infrequently and want the cheapest paid start
Brevo is the cheapest way into paid email marketing, and it bills differently from everyone else here: by emails sent, not by list size. Starter costs $9 a month for 5,000 emails, and the free plan sends 300 emails a day while storing up to 100,000 contacts — the most generous free tier in this list. Transactional email, SMS and WhatsApp live in the same account, so a startup can run its whole messaging stack from one login.
The limits are easy to miss. Starter caps contacts at 500 on the $9 tier, so a bigger list costs more, and automation does not start until Standard at $18. The Brevo logo also stays on Starter emails unless you pay to remove it. Pick Brevo when you email a big list rarely and want the lowest bill.
What we like
- Cheapest paid entry here at $9 a month, and the only tool that bills by emails sent, not list size
- Free plan sends 300 emails a day and stores up to 100,000 contacts
- Transactional email, SMS and WhatsApp sit in the same account as marketing email
Watch out for
- Starter caps contacts at 500 on the $9 tier — a bigger list pushes the price up fast
- No marketing automation on Starter; it starts on Standard at $18 a month
- Removing the Brevo logo from emails costs extra on Starter
MailerLite
Best for: Solo founders and small teams who want the simplest editor and honest, low pricing
MailerLite is the simplest tool in this list, and that is the point. The drag-and-drop editor is the easiest here, the Comfort plan removes MailerLite branding and adds unlimited templates, dynamic content and an AI writing assistant for $12 a month, and digital products sell with 0% commission. Landing pages, signup forms and automations are included on every plan, so a solo founder can run the whole funnel from one account.
The limits are modest but real. Comfort caps monthly sends at ten times your subscriber tier, so heavy senders need Power at $25 a month, and there is no phone support — live chat starts on Power too. The free plan also shrank in 2026 to 250 subscribers and 2,500 emails. Pick MailerLite when you want the fastest route from signup to first send.
What we like
- Cleanest interface in this list — a new founder can send a first campaign within an hour
- Comfort removes MailerLite branding and adds unlimited templates, dynamic content and an AI writing assistant
- Sells digital products with 0% commission and includes landing pages and signup forms on every plan
Watch out for
- Comfort caps monthly sends at 10x your subscriber tier — heavy senders need Power at $25 a month
- No phone support, and live chat starts on the Power plan
- Account approval can be strict, and reviewers report unexplained account closures
Kit
Best for: Creators and newsletter-first startups who monetize an audience with paid newsletters or digital products
Kit, formerly ConvertKit, is built for creators: bloggers, newsletter writers, podcasters and course sellers. The free plan covers up to 10,000 subscribers with unlimited sends — a ceiling no other tool here matches — and the Creator plan adds an unlimited visual automation builder, subscriber tagging and the ability to sell paid newsletters and digital products in the same account.
The price is the honest catch. Creator rose from $29 to $39 a month in September 2025, so at 1,000 subscribers Kit is the most expensive entry in this list, and advanced A/B testing waits for Creator Pro at $79. The editor is also deliberately plain next to Mailchimp's templates. Pick Kit when the newsletter itself is the business, not just a channel.
What we like
- Free plan covers up to 10,000 subscribers with unlimited sends — the highest free ceiling here
- Visual automation builder and subscriber tagging are built for creators, not corporate marketers
- Sell paid newsletters and digital products in the same account, with a 3.5% + 30c transaction fee
Watch out for
- Creator jumped from $29 to $39 a month in September 2025 — the steepest recent rise in this list
- Advanced A/B testing is held for Creator Pro at $79 a month
- No visual template library to match Mailchimp or MailerLite; the editor is deliberately plain
ActiveCampaign
Best for: Startups that need serious automation and a built-in CRM from day one
ActiveCampaign is the automation platform in this list. The Starter plan already includes multi-step visual workflows with conditional paths, a built-in CRM with deal pipelines and lead scoring, and 750-plus automation recipes — the kind of depth the simple senders cannot match. For a startup that sells by email rather than just sending a newsletter, that depth is the product.
It is also the only tool here with no free plan at any list size, only a 14-day trial, and Starter caps each automation at five actions with a single user. The price climbs fast too: Starter is $149 a month at 10,000 contacts. Pick ActiveCampaign when automation and CRM matter from day one, not as an upgrade.
What we like
- Deepest automation in this list: multi-step visual workflows with conditional paths from the Starter plan
- Built-in CRM with deal pipelines and lead scoring, so email and sales live in one place
- 750+ automation recipes and 110+ integrations, including Shopify and Salesforce
Watch out for
- No free plan at any list size — only a 14-day trial before you pay
- Starter caps automations at 5 actions each and 1 user, so real journeys need Plus at $49 a month
- Price climbs fast with contacts — Starter is $149 a month at 10,000 contacts
GetResponse
Best for: Startups that want email, landing pages, webinars and courses from one vendor
GetResponse is the all-in-one in this list: email, landing pages, signup forms, popups and — uniquely here — webinars, all in one subscription. The Starter plan costs $19 a month for 1,000 contacts with unlimited monthly sends, and the free account covers 500 contacts and 2,500 newsletters a month. For a startup running webinars or courses, that bundle replaces two or three separate tools.
The catch is the single automation workflow on Starter. A welcome series plus one abandoned-cart sequence already needs two workflows, so real automation starts on Marketer at $59 a month. AI content generation is also limited to three uses on Starter. Pick GetResponse when webinars or landing pages matter as much as the emails themselves.
What we like
- Only tool here with webinars built in — Marketer adds webinars for up to 100 attendees
- Unlimited monthly email sends on every paid plan, whatever the list size
- Landing page builder, signup forms, popups and ecommerce integrations on the Starter plan
Watch out for
- Starter allows only 1 custom automation workflow — real automation needs Marketer at $59 a month
- AI content generation is limited to 3 uses on Starter
- No phone support on the entry plan, and prices are shown net of tax
Constant Contact
Best for: Event-led startups and nonprofits that want real phone support
Constant Contact is the oldest name in this list, and it sells on simplicity and support: a human on the phone on every plan, including the $12 Lite tier, plus event invitations with RSVP tracking and social posting built in. It also publishes the strongest deliverability claim here — a 98% inbox rate from Validity's 2025 Everest test — and the 60-day free trial needs no credit card.
The pricing steps are the thing to watch. Lite jumps from $12 to $30 a month the moment you add contact 501, there is no free plan at all, and Lite allows only one automation template. The Constant Contact logo also stays on Lite emails unless you ask Support to remove it. Pick it when events or phone support matter more than the lowest price.
What we like
- Phone, chat and email support on every plan, including the $12 Lite tier
- Event invitations with RSVP tracking and social posting built into every plan
- Cites a 98% inbox rate from Validity's 2025 Everest test, the strongest deliverability claim here
Watch out for
- Lite jumps from $12 to $30 a month the moment you add contact 501 — the steepest step in this list
- No free plan; the 60-day trial is the only free route, and Lite has one automation template
- Constant Contact branding stays on Lite emails unless you ask Support to remove the logo
HubSpot Marketing Hub
Best for: Startups already running on HubSpot's free CRM that want email inside it
HubSpot Marketing Hub is the CRM-first pick. The free CRM holds up to a million contacts, and email, forms, live chat and ads all read from the same database — no syncing, no exports, no duplicate records. Starter costs $20 a month per seat with 1,000 marketing contacts included, removes HubSpot branding, and adds 500 HubSpot Credits for the platform's AI features.
The pricing model is the risk. Per-seat billing means a second teammate doubles the base price, extra contacts cost about $50 a month per 1,000, and the jump to Professional is $890 a month plus a $3,000 onboarding fee. Pick HubSpot when your sales already live in its CRM; as a standalone email tool for a two-person startup, it is the priciest route here.
What we like
- Free CRM holds up to 1 million contacts, and email, forms, live chat and ads share the same database
- Starter removes HubSpot branding and includes 1,000 marketing contacts and 500 HubSpot Credits
- 192 integrations and the most complete reporting in this list, with attribution on higher tiers
Watch out for
- Starter is priced per seat, so a second teammate doubles the bill before any contacts are added
- The jump to Professional is $890 a month plus a $3,000 onboarding fee — a 45x cliff
- Extra marketing contacts cost about $50 a month per 1,000, so the bill grows with the list
The best email marketing platforms for startups are the ones that stay cheap while your list is small and do not punish you for growing. This list ranks eight of them by fit for a typical startup: a small team, a list under a few thousand contacts, and a budget that notices every $10 a month. Prices are the entry paid tier at the smallest list size, and every free plan is called out so you can start at $0 where that is honest.
What an email marketing platform actually does
An email marketing platform stores your contacts, sends campaigns to them, and reports who opened, clicked and unsubscribed. The better ones add automation — a welcome series when someone signs up, a nudge when a cart is abandoned — plus signup forms, landing pages and segmentation so the right people get the right email. Deliverability is the quiet feature that matters most: an email that lands in spam is an email that never existed.
Constant Contact cites a 98% inbox rate from Validity's 2025 Everest test, which is the strongest deliverability claim any vendor in this list publishes. The rest of the choice is price structure, and that is where these eight tools split three ways: most charge by list size, Brevo charges by emails sent, and HubSpot charges per seat plus per 1,000 contacts.
Free options first
If your list is tiny, you may not need to pay at all. Kit's free plan covers up to 10,000 subscribers with unlimited sends, Brevo sends 300 emails a day and stores up to 100,000 contacts free, and GetResponse and HubSpot both offer genuine free accounts. Mailchimp and MailerLite both cut their free plans in 2026 — Mailchimp to 250 contacts and 500 sends a month, MailerLite to 250 subscribers and 2,500 emails — so check the current limits before you build on them.
Free plans work for a newsletter finding its feet; the moment you need automation, branding removal or more sends, a paid plan is cheaper than the workarounds. If your list serves a local business, our guide to email marketing for local business covers the local angle, including events and in-store signup.
Simple senders vs automation platforms
The eight tools split into two camps. The simple senders — MailerLite, Kit, Brevo and Constant Contact — do email well and stay out of your way. They are the right pick when a newsletter and a welcome series are the whole job. The automation platforms — ActiveCampaign, HubSpot and GetResponse, with Mailchimp in the middle — bundle email with a CRM, deeper segmentation and multi-step journeys.
They cost more per contact but replace a second subscription. If you already run your sales in HubSpot's free CRM, its email is the obvious next step; if you only need newsletters, a simple sender costs a third as much. The traffic that fills the list has to come from somewhere — if search is your channel, our monthly SEO service is the other half of this setup.
Know the difference: priced by contacts, by sends, or by seat
The biggest confusion in this category is the billing unit, because the same list costs a different amount on each tool. Mailchimp, Kit, GetResponse, Constant Contact and ActiveCampaign charge by list size: more contacts, higher tier, and the price steps up in bands — Constant Contact Lite jumps from $12 to $30 the moment you add contact 501. Brevo charges by emails sent instead, so a big list emailed rarely is cheap and a small list emailed daily is not.
HubSpot charges per seat and per 1,000 marketing contacts, so a second teammate doubles the base price before you send anything. Before you compare sticker prices, decide which unit matches how you actually email: a monthly newsletter to a big list favors Brevo, a daily sender favors a contact-priced plan, and a team of two favors anything but per-seat billing. For the wider automation picture, see marketing automation for small business.
Email marketing platforms for startups pricing: what you will actually pay
Take a startup with 500 contacts sending one newsletter a week — about 2,000 emails a month — for a year. On monthly billing, Brevo Starter costs $9 a month, or $108 a year, and drops to $8.08 a month billed annually, or $96.96 a year. MailerLite Comfort costs $12 a month, or $144 a year, and $10.80 a month billed annually, or $129.60 a year. Constant Contact Lite is the same $12 a month, or $144 a year, falling to $10.20 a month prepaid annually, or $122.40 a year. Mailchimp Essentials lists $13 a month with no annual-billing figure in this list, so it comes to $156 a year on the monthly rate.
At the dear end, Kit Creator costs $39 a month, or $468 a year, and $33 a month billed annually, or $396 a year. ActiveCampaign Starter costs $19 a month billed monthly, or $228 a year, and $15 a month billed annually, or $180 a year; GetResponse Starter is also $19 a month, or $228 a year, falling to $15.58 a month billed annually, or $186.96 a year. HubSpot Starter costs $20 a month per seat, or $240 a year for one seat and $480 a year for two. On annual billing the same year of email costs $96.96 at the cheap end and $396 at the dear end — a $299.04 gap that comes from automation, CRM and creator tools, not from the emails themselves.
Two costs sit outside those numbers. First, the list-size steps: Constant Contact Lite jumps from $12 to $30 a month at 501 contacts, so this scenario only just fits the $12 tier; Mailchimp Essentials is about $75 a month at 5,000 contacts and ActiveCampaign Starter is $149 a month at 10,000, while HubSpot charges about $50 a month per extra 1,000 marketing contacts. Second, the entry tier leaves things out: Brevo Starter caps contacts at 500, has no marketing automation and charges extra to remove its logo, and GetResponse lists its prices net of tax. Price the list you expect in a year, not the list you have today.
Quick comparison: tool type by need
| Buyer | Best pick | Why |
|---|---|---|
| Startup on a $10 budget | Brevo | $9 a month for 5,000 emails, free plan sends 300 a day |
| Solo founder who wants simple | MailerLite | Cleanest editor, branding removed from $12 a month |
| Creator or newsletter business | Kit | Free to 10,000 subscribers, paid newsletters built in |
| Automation and CRM from day one | ActiveCampaign | Deepest workflows plus a built-in CRM from $15 a month billed annually |
| Email plus webinars and pages | GetResponse | Landing pages and webinars in one subscription from $19 a month |
| Events, nonprofits, phone support | Constant Contact | A human on the phone on every plan, from $12 a month |
| Already on HubSpot CRM | HubSpot Marketing Hub | Email inside the free CRM, from $20 a month per seat |
How to choose the best email marketing platforms for startups
- Count your contacts and your sends. Under 500 contacts, six of these tools are free or under $15 a month; over 5,000, the per-contact price decides.
- Pick your billing unit. Rare sends to a big list favor Brevo's per-email pricing; frequent sends favor contact-priced plans; teams should avoid per-seat pricing.
- Decide simple sender or automation platform. If a newsletter and a welcome series are the job, MailerLite or Kit cost a third of ActiveCampaign.
- Check the free plan's real limits. Mailchimp's 500 sends a month covers one weekly email to 125 people — do the maths before you build on it.
- Try before you pay. Every tool here has a free plan or a free trial; send a real campaign to your real list and check the inbox rate before committing.
Before you send your first campaign, run your signup page title through the free SERP snippet preview tool — it shows exactly how the page will look in Google, which is where most new subscribers find you.
Mistakes to avoid
- Comparing sticker prices without checking the billing unit. A $9 plan billed by sends and a $13 plan billed by contacts are not the same $9 and $13.
- Building on a free plan without reading its send cap. Mailchimp's free plan allows 500 sends a month — one weekly email to 125 subscribers already uses it up.
- Paying for automation you will not use. Starter plans with one workflow are fine for a welcome series; multi-step journeys need the next tier up.
- Trusting a directory price. Kit's Creator plan rose from $29 to $39 a month in September 2025, and older roundups still show the old figure. Always check the vendor's own page.
- Forgetting the price steps. Constant Contact Lite doubles from $12 to $30 at 501 contacts, and ActiveCampaign Starter is $149 a month at 10,000 contacts — price the list you will have in a year, not today.
How we chose
We checked each vendor's own pricing page and recorded the starting price exactly as shown, including the annual-billing figure where the page lists one. Two prices were confirmed on the vendor pages a few days earlier rather than today — ActiveCampaign on October 29, 2026 and GetResponse on October 26, 2026 — because our page reader hit a rate limit on November 4; both figures were cross-checked against multiple independent reads of the same pages. Ratings come from G2, checked November 4, 2026, with review counts shown. We ranked the tools by fit for the most common buyer — a startup founder with a small list and a tight budget — not by brand size. No vendor paid for a place in this list, and none of the links here are affiliate links.
What to do next
Start with the decision path above: count your contacts, pick your billing unit, and decide simple sender or automation platform. Then take the free plan or trial of your top pick and send a real campaign to your real list — if it lands in the inbox and the reports make sense, you have your tool. If the list is already on one of these platforms and growing fast, re-price it at the list size you expect in a year before you renew. Once your tools are in place, find out what's holding your rankings back.

Frequently asked questions
What is the best email marketing platform for startups?
Brevo is the cheapest paid start at $9 a month, Mailchimp is the safest all-rounder from $13 a month, and MailerLite is the simplest at $12 a month. If you sell to creators, Kit's free plan covers 10,000 subscribers. The right pick depends on your billing unit: Brevo charges by emails sent, most others by list size, and HubSpot per seat.
How much does email marketing cost for a startup?
Between $0 and $39 a month at the entry level. Brevo starts at $9, MailerLite at $12, Constant Contact at $12 and Mailchimp at $13, while Kit's Creator plan is $39. Six of the eight tools have free plans, so a list under a few hundred contacts can cost nothing until it grows.
Is there a free email marketing platform for startups?
Yes, with limits. Kit's free plan covers up to 10,000 subscribers, Brevo sends 300 emails a day free, and GetResponse and HubSpot offer free accounts. Mailchimp's free plan is now capped at 250 contacts and 500 sends a month, and MailerLite's at 250 subscribers — both shrank in 2026.
Mailchimp vs Brevo: which is cheaper for a startup?
Brevo, in most cases. Brevo Starter is $9 a month for 5,000 emails, while Mailchimp Essentials is $13 a month for 500 contacts — and Brevo bills by sends, not list size, so a large list emailed rarely stays cheap. Mailchimp wins on integrations and templates; Brevo wins on the bill.
What is the difference between pricing by contacts and by emails sent?
Contact-priced tools (Mailchimp, Kit, Constant Contact) charge more as your list grows, however often you email. Send-priced tools (Brevo) charge by monthly email volume, so a big list emailed once a month is cheap. HubSpot is different again: it charges per seat plus per 1,000 marketing contacts.
Can I switch email marketing platforms later?
Yes. Every tool here imports contacts by CSV, and most offer a free migration service — Kit's team rebuilds your forms, templates and automations for paid plans. Export your list and your automation maps before you cancel, and run both tools in parallel for one send cycle to compare deliverability.
Do I need marketing automation as a startup?
A welcome series, yes — it is the highest-return automation for a new list, and every tool here includes at least a basic version on its entry plan. Multi-step journeys and lead scoring can wait until the list passes a few thousand contacts; until then, a simple sender costs a third of an automation platform.
