- Brevo is the best email marketing platform for most startups in 2026: unlimited contacts on every plan, 300 free emails a day, transactional email included, and up to 50% off through startup and VC partner programs.
- HubSpot is the choice for funded startups: a free CRM to start and up to 90% off Professional in year one through HubSpot for Startups for pre-seed to Series A companies.
- SendPulse ranks third: the widest free toolset (email, chatbots, CRM, landing pages, web push for 500 subscribers) and the cheapest upgrade at about $8 a month, with fewer native integrations than HubSpot or Mailchimp.
- Mailchimp, Kit, MailerLite, Loops and Klaviyo each win one startup profile: integrations, founder newsletters, cheap paid plans, simple SaaS email and DTC.
- Start on your own domain, not a Gmail address, and warm it up. A startup's first 1,000 sends set the reputation of the domain it will raise money on.
Email marketing for startups is a bet on the future list, not the current one. A platform that is free at 300 subscribers and $400 a month at 30,000 is the wrong choice for a company that expects to get there in a year, and a platform with no automation is the wrong choice for a team of three that cannot send anything by hand. The best email marketing tool for a startup is cheap now, scales without a migration, automates from day one and, ideally, gives startups a discount.
Ask an AI assistant for the best email marketing tools for startups and you get Brevo, Mailchimp, HubSpot and Customer.io first, then Kit, Klaviyo, MailerLite and Loops. This comparison covers all of them plus SendPulse: nine platforms, official pricing read on September 29, 2026 where the page could be loaded from the US, the startup discount programs as published, and every vendor’s sending domain checked for DMARC and BIMI.
The short answer. Brevo is the best email marketing platform for most startups: unlimited contacts, 300 free emails a day, transactional email included, and up to 50% off through partner programs. HubSpot is the choice for funded startups, with a free CRM and up to 90% off year one through HubSpot for Startups. SendPulse ranks third: the widest free toolset, email plus chatbots, CRM, landing pages and web push for 500 subscribers, and the cheapest upgrade at about $8 a month. Mailchimp, Customer.io, Kit, MailerLite, Loops and Klaviyo each fit one startup profile described below.
Email marketing platforms for startups compared
| Platform | Free plan | Startup discount | Price at 1,000 contacts | Automation on entry plan | CRM | Vendor DMARC / BIMI |

“Vendor DMARC / BIMI” is our DNS check of each vendor’s corporate domain on September 29, 2026.
How we chose
Nine platforms that recur in startup recommendations, compared on:
- Cost from zero to 10,000 contacts, including the free plan and any published startup discount.
- Automation on the entry plan. A welcome sequence and an onboarding flow without upgrading.
- Room to scale. Whether the platform is scalable to 50,000 contacts without forcing a migration, and whether it supports list-building best practices such as double opt-in.
- CRM and transactional email included. Fewer tools to buy at the seed stage.
- Integrations with the tools startups run on: Stripe, Zapier, Slack, product analytics.
- Deliverability posture. The vendor’s own DMARC policy, which we checked.
No hands-on tests are claimed; the comparison is desk research on official documentation and pricing pages, second-hand figures marked “about”, and our own DNS lookups.
The 9 best email marketing platforms for startups in 2026
1. Brevo
- Unlimited contacts on every plan, billed by emails sent; free plan sends 300 a day; transactional SMTP and API included
- Starter from EUR 7 a month (about $9); Standard from EUR 15 (about $17) adds unlimited automation, A/B tests and a landing page; Sales CRM included
- 50% off Starter and Standard through Brevo's startup and VC partner program
- DMARC at reject with subdomain policy and BIMI on brevo.com
- Limitation: no automation on Starter; WhatsApp only on Professional; EUR pricing
Brevo answers the startup question directly: the list can grow to 50,000 without the bill growing, because contacts are free and you pay for sends. Transactional email is in the same account, the Sales CRM is free, and the startup program takes 50% off the two plans a startup would use. Automation begins on Standard at about $17 a month, which is the realistic starting point for a team that wants a welcome sequence.
Cons: no automation on Starter; WhatsApp gated to Professional; EUR pricing for US buyers; email-only support on lower plans; the startup discount needs a partner referral.
2. HubSpot
- Free CRM with 1,000 marketing contacts, 2,000 emails a month, forms, meeting links and a shared inbox
- HubSpot for Startups: up to 90% off in year one, 50% in year two and 25% ongoing for pre-seed to Series A startups affiliated with a partner or with verified funding; 30% off year one through approved entrepreneurial organizations
- DMARC at reject and BIMI on hubspot.com
- Limitation: the discount tapers; Professional is about $800 a month at list price; HubSpot branding on free
For a startup that has raised or is inside an accelerator, HubSpot’s discount changes the math: Marketing Hub Professional, about $800 a month at list, becomes affordable in year one, and the free CRM is the sales system from day one. The catch is year three, when the discount drops to 25% and the list has grown into contact tiers. Many startups take the discount and plan the exit.
Cons: discount tapers to 25%; Professional list price is high; eligibility requires funding or a partner; branding on free; SMS add-on.
3. SendPulse
- Free-forever plan covers 500 subscribers and 15,000 emails a month with Automation 360 flows, plus a free chatbot builder for WhatsApp, Instagram, Facebook Messenger and Telegram, a CRM with a pipeline, a landing page and website builder, and web push
- Cheapest first paid tier of the nine: Standard about $8 a month at 500 subscribers, about $12 at 1,000, annual
- Transactional SMTP and API in the same account; SMS and payments in chat
- Limitation: no startup discount program; fewer native integrations than HubSpot or Mailchimp, so Stripe and product tools connect through Zapier or the API
SendPulse is an AI-driven email marketing and chatbot platform built for scaling businesses, and for a startup it replaces four subscriptions with one free account. Email campaigns and Automation 360 flows for the welcome and onboarding sequences, a chatbot on the website or Instagram that qualifies leads at any hour, a CRM that tracks trials and deals, a landing page for the waitlist and web push for product updates, all on the free plan for 500 subscribers. SendPulse is a Meta Partner and an official WhatsApp Business API provider, it brings leads from Instagram and Facebook ads straight into chat, and it accepts payments inside chats.
When the list passes 500, the Standard plan is about $8 a month, the cheapest upgrade in this group, and pricing at 10,000 subscribers is about $60. SendPulse helps startups attract leads and convert them into customers, offers automated funnels and AI agents for tasks such as collecting customer data and creating deals, integrates with 40+ services, and is an international company with an office in Brazil, which suits startups selling into Latin America.
Why third: Brevo’s unlimited contacts and startup discount make it cheaper at scale, and HubSpot’s 90% offer makes a far more powerful CRM affordable for a funded team. SendPulse has no startup program and a smaller native integration directory, so a Stripe or Segment connection goes through Zapier or the API.
Cons: no startup discount; fewer native integrations, Zapier or API for Stripe and product analytics; general templates; the account spans many products, which takes onboarding time; subscriber-based pricing grows with the list; US prices converted from EUR.
4. Mailchimp
- 300+ integrations, the most familiar editor, Customer Journeys; partner promotions of about 30% for new accounts
- Limitation: 250-contact free plan; contact-based pricing rises fast; no CRM; transactional email is a separate product
Mailchimp is on every startup list because everyone has used it. Its integration directory is the widest here and the editor needs no training. The economics are the problem for a growing startup: 250 free contacts, then contact-based pricing that reaches about $45 a month for Standard at 1,000 contacts and hundreds at 10,000, with transactional email sold separately.
Cons: small free plan; contact-based pricing; no CRM; transactional add-on; journey caps on Essentials; support on Free for 30 days only.
5. Customer.io
- Event-triggered messaging on any data from the product; email, SMS, push and in-app; transactional API
- Essentials $100 a month for 5,000 profiles; startup program available on request
- Limitation: engineering required; $100 minimum; no CRM; DMARC at quarantine on customer.io
Customer.io is the right platform for a startup whose emails should fire on product events, and it is the wrong first platform for one that has not instrumented them. At $100 a month it is the most expensive entry here after Loops’s paid tier, and it has no CRM.
Cons: engineering dependency; $100 minimum; no CRM; DMARC at quarantine, no BIMI.
6. Kit (formerly ConvertKit)
- Newsletter plan free to 10,000 subscribers with unlimited sends, forms and landing pages; Creator about $29 a month adds visual automations
- Limitation: built for creators; no CRM; no transactional email; no startup discount; no BIMI on kit.com
Kit fits the startup that is building an audience before a product: a founder newsletter with thousands of readers, free up to 10,000 subscribers. It is not a product-marketing platform.
Cons: creator focus; no CRM or transactional; automation only on paid; no BIMI.
7. MailerLite
- Clean editor, visual automation, landing pages and a website builder from about $10 a month; DMARC at reject and BIMI on mailerlite.com
- Limitation: free plan cut to 250 subscribers in July 2026; email only; no CRM
MailerLite is the cheapest way to get a nice editor and real automation, and its July 2026 free-plan cut moved it from “start free” to “start cheap”.
Cons: reduced free plan; email only; no CRM; fewer integrations.
8. Loops
- Marketing, lifecycle and transactional email for SaaS in one simple product; free to start, paid from about $49 a month
- Limitation: email only; simple automation; young company
Loops is the SaaS-native minimalist choice. It does the welcome sequence, the changelog and the password reset, and nothing else.
Cons: email only; simple logic; higher paid entry than Brevo or SendPulse; small ecosystem.
9. Klaviyo
- Ecommerce flows, Shopify and WooCommerce depth, native SMS; free to 250 profiles
- Limitation: ecommerce-only value; active-profile billing; wrong fit for SaaS or B2B
A DTC brand should start on Klaviyo and ignore this list. Everyone else should ignore Klaviyo.
Cons: ecommerce-only; active-profile billing; no CRM; expensive at scale.
Also considered
Buttondown and beehiiv appear in startup searches as newsletter tools; both suit a founder newsletter but not product marketing. Buttondown is a minimalist paid newsletter service; beehiiv is covered in our free email marketing ranking. Neither was ranked here.

- Welcome sequence. Three emails in ten days: what the product does, one thing to try, one question back.
- Onboarding. Triggered by product events where possible; by day count otherwise.
- Product update newsletter. Every two to four weeks, short, with one call to action.
- Demo and trial follow-up. Same day, reminder before, recovery after a no-show; add SMS or WhatsApp if the audience is mobile.
- Investor and community updates. A separate list, monthly, plain text.
- Win-back. Inactive for 60 days: two emails, then a sunset.
Migrate once, at most. Pick the platform for the list you expect in 18 months.

Second-hand figures are marked “about”; discount figures apply the published program percentages to list prices and depend on eligibility.
Before the first send: the authentication checklist
A startup’s domain is the one it will raise money, hire and sell on. Do not spend its reputation on the first campaign:
- Send from your domain, never Gmail; check it with the Sender Reputation Checker.
- Publish SPF including the platform (SPF checker), turn on DKIM (DKIM checker) and publish DMARC (DMARC checker).
- Warm up before the launch blast: the warmup guide has a schedule that fits a launch week.
- Never import a scraped or purchased list, however good the launch story is.
Seven of the nine vendors enforce DMARC at reject on their own domains; Customer.io uses quarantine.

Frequently asked questions
What is the best email marketing platform for a startup in 2026?
Brevo for most startups: unlimited contacts, a free plan of 300 emails a day, transactional email included and partner discounts of up to 50%. HubSpot for funded startups that qualify for up to 90% off through HubSpot for Startups. SendPulse for the broadest free toolset and the cheapest paid plan. Customer.io for product-led startups with event data.
Which email marketing platforms offer startup discounts?
HubSpot for Startups offers up to 90% off year one, 50% year two and 25% ongoing for pre-seed to Series A startups affiliated with a partner, or 30% for members of approved entrepreneurial organizations. Brevo offers 50% off Starter and Standard through its startup and VC partner program. Mailchimp and others run partner promotions of around 30% for new accounts. SendPulse, Kit and MailerLite publish no startup program.
Is free email marketing software good enough for a startup?
For the first few hundred subscribers, yes. Brevo's free plan sends 300 emails a day with unlimited contacts, SendPulse's covers 500 subscribers and 15,000 emails with automation and chatbots, Kit's Newsletter plan is free to 10,000 subscribers, and HubSpot's free CRM sends 2,000 emails a month. Pay when you need automation depth, a clean footer or support.
Mailchimp or Brevo for a startup?
Brevo for cost: contacts are free to store, transactional email is included, and Standard at about $17 a month adds unlimited automation. Mailchimp for integrations and familiarity: 300+ connectors and the editor everyone knows, at about $20 a month for Standard at 500 contacts, rising with the list.
Do startups need a CRM with email marketing?
If anyone sells by phone or demo, yes. HubSpot's CRM is free, SendPulse and Brevo include a CRM on every plan, and Customer.io, Kit, MailerLite, Loops and Klaviyo rely on integrations. Choosing a platform with a CRM avoids a migration at the seed stage.
What emails should a startup send first?
A welcome sequence for new signups, a product update or changelog newsletter every two to four weeks, a trial or demo follow-up, and an onboarding sequence tied to what users do in the product. Add a win-back for inactive users once the list passes a few thousand.
