Email-marketing Comparisons

Constant Contact prices three plans by contact count: Lite $12 a month or $9 billed annually, Standard $35 or $26.25, Premium $80 or $60, with 10x, 12x and 24x monthly sends and 1, 3 and unlimited users. Mailchimp prices four: Free up to 250 contacts, Essentials $13, Standard $20 and Premium $350 a month for a 500-contact list. Both bills grow with your list; the difference is who you become as it grows, a small-business marketing suite or a general-purpose email platform.

Kit charges per list size: a free plan the vendor lists at up to 10,000 subscribers, Creator at $33 a month billed yearly for 1,000 subscribers, Pro at $66 a month billed yearly with a first-year offer at $50. Substack charges nothing to publish, then keeps 10% of paid subscription revenue plus Stripe's 2.9% plus 30 cents a payment and 0.7% on recurring billing. Your choice depends on whether you would rather pay a fixed bill or a percentage of what you earn.

Both platforms start free with the same ceiling — 250 people and a few hundred sends — then price by audience size. Klaviyo's email tier begins at $20 per month for 251 to 500 active profiles, and the email-plus-SMS tier at $35 for the same profile band, with $5 of mobile messages included on the free plan and email support limited to the first 60 days. Mailchimp's free plan caps at 250 contacts and 500 sends a month, and its paid ladder is Essentials at $13/mo, Standard at $20/mo and Premium at $350/mo on a twelve-month term, with sends at 10x, 12x and 15x your list. Klaviyo is built for stores that want behaviour-driven flows and SMS in one account; Mailchimp is cheaper at the small end and broader for general marketing.

HubSpot sells a suite and prices by seat and contact tier: Marketing Hub Free at $0 for up to two users with 2,000 branded sends a month, Starter from $7 per seat per month billed annually ($20 month-to-month) with 1,000 marketing contacts, Professional at $800/mo annually with three core seats and a required $3,000 onboarding, Enterprise at $3,600/mo with five seats and $7,000 onboarding. Mailchimp sells email campaigns and prices by plan: Free capped at 250 contacts and 500 sends, Essentials $13/mo, Standard $20/mo and Premium $350/mo on a twelve-month term, each scaling sends by 10x, 12x and 15x your contact count. Buy Mailchimp to send newsletters well and cheaply; buy HubSpot when marketing, CRM and sales need to share one database.

ActiveCampaign is marketing automation priced on contacts: at 1,000 contacts billed annually its page lists Starter $15, Plus $49, Pro $79 and Enterprise $145 a month, with a 14-day trial by email sign-up and a 30-day money-back promise. Salesforce Sales Cloud is a CRM priced on seats: Free Suite at $0, Starter Suite at $25, Pro Suite at $100, then Core at $195, Advanced at $395 and Max at $550 per user a month billed annually, most of it on annual contracts. The two overlap only where email meets pipeline. Choose ActiveCampaign when campaigns and automation are the centre of the business; choose Salesforce when the CRM is the system of record and marketing is one department of it.

Kit - the tool formerly called ConvertKit - prices around creators: a free plan the page labels '$0/mo, up to 10,000 subscribers' with unlimited landing pages, forms and email broadcasts, Creator at $33 a month billed yearly ($390 for the year, saving $78) quoted for 1,000 email subscribers, and Pro listed at $66 a month shown at $50 with a limited-time first-year offer of $593. Mailchimp prices around contacts: free up to 250, Essentials $13 a month for the first 12 months, Standard $20 and Premium $350 at the 0-500 contact band, with send volumes of 6,000 and 150,000 emails a month on the upper tiers. Kit buys unlimited sending and creator commerce; Mailchimp buys segmentation, testing and a lower entry price.

Substack does not charge you a subscription: publishing is free at any subscriber count, and when you turn on paid subscriptions it keeps 10% of each payment while Stripe takes 2.9% + $0.30 on US cards and 0.7% on recurring billing, with a $50 one-time fee if you want your own domain. Mailchimp charges you monthly and prices by list size: Free at $0 up to 250 contacts with sending paused if you exceed it, Essentials at $13 a month for the first 12 months, Standard at $20 and Premium at $350 at the 0-500 contact tier, with Standard sending up to 6,000 emails a month and Premium up to 150,000. Use Substack when readers pay you; use Mailchimp when you run a list, automations and campaigns and would rather pay a fixed fee than a revenue share.

ActiveCampaign prices four plans by contact count starting at 1,000: Starter $15, Plus $49, Professional $79 and Enterprise $145 a month billed annually, with unlimited automation actions on paid plans. Constant Contact prices three plans starting at 500 contacts: Lite $12, Standard $35 and Premium $80 a month, or $10.20, $29.75 and $68 when prepaid annually. Pick ActiveCampaign for automation, pick Constant Contact for a simpler bill and included SMS on top.

ActiveCampaign is a specialist: email, automation, segmentation and CRM integrations from $15 a month at 1,000 contacts. HubSpot is a platform: free CRM, Starter seats at $20, then a deliberate jump to Professional at $800 a month on annual billing with a $3,000 onboarding fee. Choose ActiveCampaign if marketing automation is the job; choose HubSpot if you want sales, service and marketing on one record.

ActiveCampaign sells automation depth and CRM integrations by contact count, with no free plan and a 14-day trial. Klaviyo sells an ecommerce-first B2C CRM with a real free tier, then charges by active profile with SMS and AI agents attached. If you run a store, start with Klaviyo's free plan; if your funnel is B2B or heavily branched, ActiveCampaign's segmentation tiers are the reason people pay.

ActiveCampaign is marketing automation with CRM and ecommerce integrations, sold by contact count with a 14-day trial and no free plan. Kit (formerly ConvertKit) is built for creators - newsletters, landing pages, digital products - and keeps a free plan up to 10,000 subscribers. At 1,000 contacts the entry prices are $15 a month against Kit's $33 Creator plan, but they buy different things.

ActiveCampaign sells automation depth on a four-tier ladder: Starter $15 a month billed annually for 1,000 contacts, Plus $49, Pro $79, Enterprise $145, with 5 actions per automation on Starter, 25 active goals on Plus and 200 goals with unlimited actions from Pro. MailerLite sells simplicity on four plans of its own: Free at $0 with 250 subscribers and 2,500 monthly emails, Comfort from $12 a month as the full toolset for small senders, Power from $25 with unlimited automations, forms, sites, digital products and user seats, and Enterprise by conversation. Choose ActiveCampaign if branching automation and CRM features justify the higher entry; choose MailerLite if the list is small, the budget is thin and unlimited emails at $12 matters more than goal-based logic.

ActiveCampaign prices automation depth: Starter at $15 a month billed annually for 1,000 contacts, Plus at $49, Pro at $79 and Enterprise at $145, with 5 automation actions per automation on Starter, 25 active goals on Plus and 200 goals with unlimited actions from Pro, and one to five users by tier. Mailchimp prices the list: Free up to 250 contacts, Essentials at $13 a month for the first 12 months, Standard at $20 and Premium at $350, all at the entry contact tier shown on its pricing page, with an extra 15% off for lists over 10,000 contacts in year one. Choose ActiveCampaign if automation is the product you are buying; choose Mailchimp if campaigns, a familiar editor and a free entry point matter more than branching logic.

Constant Contact prices Lite at $10.20 per month billed annually, Standard at $29.75 and Premium at $68, with monthly email sends set as a multiple of your contact count (10x on Lite, 12x on Standard, 24x on Premium) and 1, 3 and 3 users respectively; its page notes the plan price depends on contacts and sends, with overage fees possible. MailerLite's Free plan covers up to 250 subscribers, 2 user seats and 2,500 monthly emails; Comfort starts at $12 per month with the full template and testing toolkit, and Power at $25 adds unlimited user seats, unlimited monthly emails, digital products and bookings. Constant Contact is the more complete small-business suite with events, ads and phone support; MailerLite is the cheaper path to unlimited sending and unlimited seats.

Beehiiv is a newsletter product priced per publication: Free at $0 with unlimited email sends, Lite at $49 per month billed yearly with paid subscriptions at a 0% take rate, Pro at $95 to remove branding. HubSpot is a customer platform whose Marketing Hub starts free for up to 2 users, sells Starter at $7 per seat per month, then jumps to $800 per month for Professional (annual billing, includes 3 core seats, 2,000 marketing contacts and 3,000 credits) and $3,600 for Enterprise with a required $7,000 onboarding fee. A publication sending newsletters is cheaper and faster on beehiiv; a company that wants email, CRM, ads, landing pages and reporting on one database is buying HubSpot, and paying a steep step between Starter and Professional for it.

Beehiiv sells newsletter publishing: Free at $0 with unlimited email sends, Lite at $49 per month billed yearly for paid subscriptions with a 0% take rate, Pro at $95 to remove branding. Klaviyo sells an ecommerce CRM: free to 250 active profiles with 500 emails a month, an Email plan that its own pricing page estimates around $20 per month for 5,000 emails, and a Marketing tier estimated around $90 that adds SMS, push, Customer Hub, predictive analytics and loyalty tools. Beehiiv is cheaper and simpler for a growing subscriber list; Klaviyo is built for stores that need profile-level data, segmentation and revenue attribution across email and SMS.

Beehiiv's Free plan costs $0 and lists unlimited email sends, templates, landing pages, its recommendation network and API access; paid subscriptions with a 0% take rate start on the Lite plan at $49 per month billed yearly, and Pro is $95 per month to remove beehiiv branding. Substack costs nothing to publish, and it monetizes by keeping 10% of your paid subscription revenue on top of payment processing (writers keep 90% minus card fees). The choice inverts with revenue: a free newsletter is free on both, and a paid one costs $49+ per month flat on Beehiiv but 10% of everything on Substack, so the break-even sits around a few hundred dollars of monthly subscription income.

Beehiiv is built around newsletters and monetization: Free holds up to 2,500 subscribers with unlimited sends, Lite is $49 a month yearly, Pro is $95, and Enterprise is a quote. Mailchimp is a general email platform: Free exists for small lists, and the paid tiers it shows run $13, $20 and $350 a month for the first 12 months at the selected contact level, with pricing stepping up after. Beehiiv gives away more at the free tier and charges for monetization tooling; Mailchimp has the lower entry price and a wider marketing feature set.

Substack charges no monthly fee: publishing is free with unlimited subscribers, and paid subscriptions cost 10% of each payment to Substack plus Stripe's 2.9% + $0.30 card fee and 0.7% recurring billing fee, with an optional custom domain at a one-time $50. MailerLite charges a fixed subscription instead: Free to 250 subscribers with 2,500 monthly emails and 2 seats, Comfort at $10.80 a month billed annually for up to 500 subscribers, Power at $22.50 a month with unlimited emails and seats, and Enterprise negotiated for 200K+ subscribers. Substack is cheaper at zero revenue and gets expensive as income grows; MailerLite costs the same whether the list earns nothing or a lot.

beehiiv prices a publishing platform: Free with unlimited sends up to 2,500 subscribers and 1 team seat, Lite at $49 a month billed yearly up to 100,000 subscribers with paid subscriptions at a 0% take rate and ad monetization, Pro at $95 a month up to 250,000 subscribers with branding removed and 24/7 priority support, and Enterprise by quote with SSO/SAML and dedicated IPs. MailerLite prices an email list: Free to 250 subscribers with 2,500 monthly emails and 2 seats, Comfort at $10.80 a month billed annually for up to 500 subscribers with 3 seats, Power at $22.50 a month with unlimited emails and seats, and Enterprise negotiated for 200K+ subscribers. Pick beehiiv when monetization features are the point; pick MailerLite when the job is sending newsletters and automations cheaply.

HubSpot sells a marketing platform: free tools for up to 2 users with 2,000 email sends a month and HubSpot branding, Starter at $7 a month on the current promotional price against a listed $20, Professional at $800 a month billed annually with three core seats, 2,000 marketing contacts and a required $3,000 onboarding, and Enterprise at $3,600 with five core seats and a $7,000 onboarding fee.

The gap in price is the gap in scope — CRM, agents and reporting suites against an email tool priced by list size.

Beehiiv runs a free plan up to 2,500 subscribers with one team seat, Lite at $49 per month billed yearly up to 100,000 subscribers and Pro at $95 up to 250,000, all shown at the 1,000-subscriber tier, plus a custom Enterprise plan. Kit, the platform still searched as ConvertKit, lists a free plan, Creator at $33 per month billed yearly and Pro at $66 at the same subscriber tier. Beehiiv is built for growth and monetisation loops; Kit is built for selling to an audience you already have.

Mailchimp splits its offer into four plans: a free plan limited to 250 contacts, Essentials from $13 per month, Standard from $20 per month and Premium from $350 per month for the first 12 months at the 0-500 contact tier, with a 14-day trial on paid plans. MailerLite keeps it to a free plan of 250 subscribers and 2,500 emails, Comfort from $12 and Power from $25, plus a negotiated Enterprise tier. Mailchimp brings SMS, deeper automation and phone support; MailerLite brings a lower entry price and a simpler editor.

ConvertKit now trades as Kit, and the platform keeps the same centre of gravity. Kit lists a free plan the pricing page labels up to 10,000 subscribers, Creator at $33 per month billed yearly ($390 per year) at the 1,000-subscriber tier, and Pro at $66 per month with a first-year offer at $50. MailerLite lists a free plan capped at 250 subscribers with 2,500 monthly emails, Comfort from $12 per month and Power from $25 per month, both scaled by subscriber tier. Kit suits creators selling products and sequences; MailerLite suits small businesses that want cheap, predictable sending.

Brevo bills around email volume and channels: Free sends up to 300 emails a day, Starter is $9 per month ($8.08 billed yearly), Standard $18 ($16.17), Professional $499 ($449.08) with 10 seats and 150,000 emails included, Enterprise from $2,499. HubSpot bills by seat and contact tier: Starter lists at $20 per seat ($7 for new customers annually), Marketing Hub Professional $800 per month and Enterprise $3,600. Brevo is the cheaper route to sending email, SMS and WhatsApp from one place; HubSpot costs more because marketing, sales and service share one system.

beehiiv and Brevo both send email, but they are built for different jobs. beehiiv is a newsletter platform: Launch costs $0 up to 2,500 subscribers with unlimited sends and a 0 percent cut of subscription revenue, with paid tiers from $49 a month. Brevo is a multi-channel marketing suite: Free up to 300 emails a day, Starter at $9 per month, Standard at $18 and Professional at $499. Pick beehiiv to grow a publication, Brevo to run marketing across email, SMS and WhatsApp.

Brevo and Constant Contact both sell email marketing to small businesses, at near-identical entry prices. Brevo's Starter is $9 per month and Standard is $18, with Professional at $499 for high volume and a free plan capped at 300 emails a day. Constant Contact's Lite is $12 per month, or $10.20 billed annually, and Premium reaches $80. Brevo is the cheaper entry point and adds SMS and WhatsApp; Constant Contact bundles social media posting and a stronger support promise.

Brevo's free plan sends up to 300 emails a day with no time limit, and its paid ladder is Starter at $9 per month and Standard at $18 per month, or $8.08 and $16.17 respectively with the yearly discount, from 5,000 emails a month, then Professional at $499 a month and Enterprise from $2,499. Kit's free plan is different in shape: $0 a month up to 10,000 subscribers, then Creator at $33 a month or $390 billed yearly and Pro at $66 a month or $790 billed yearly, both quoted for 1,000 email subscribers, so the price follows contact count rather than email volume. Brevo meters sends and scales by volume with multichannel messaging attached; Kit meters subscribers, keeps the sending volume out of the headline and bundles an audience-growth referral plan worth $99 a month into Pro.

The two vendors meter usage differently, and that is the whole decision. Klaviyo's free plan allows 250 active profiles with 500 email sends a month plus $5 of mobile messages, and its paid plans are built around how many profiles you store - a model that suits stores where every contact is a tracked customer. Brevo's free plan allows up to 300 emails a day (roughly 9,000 a month), with paid tiers from EUR 7/month priced around email volume and contacts. If your list is a store's customer file and you want SMS in the same platform, Klaviyo's model fits. If your list grows faster than your sending needs and you would rather pay for volume than for profiles, Brevo is the cheaper structure.

ActiveCampaign sells automation depth and is priced in tiers with hard feature gates: Starter at $15/month gives one user and only 5 actions per automation, Plus at $49/month unlocks 25 active goals, Pro at $79/month adds 3 users and advanced segmentation, and Enterprise at $145/month adds premium segmentation, custom objects, SSO and a dedicated account team. Brevo starts lower (EUR 7/month Starter) and gives you SMS, WhatsApp, push, live chat, chatbot and a CRM in the same subscription, with unlimited-ish sending governed by volume. Buy ActiveCampaign when the automation map is the product. Buy Brevo when you need several channels and a sales inbox without stacking subscriptions.

MailerLite is the simpler, cheaper-to-understand option: Free covers 250 subscribers and 2,500 emails a month, Comfort is $12/month with 5,000 monthly emails and 3 seats, and Power at $25/month removes the send cap entirely. Brevo charges less to enter (EUR 7/month Starter, EUR 6.33 yearly) and gives you SMS, WhatsApp, live chat, a CRM and transactional email in the same account. Choose MailerLite when email plus a few landing pages is the whole job and you want unlimited sends on a mid tier. Choose Brevo when email is one of several channels you intend to run from one platform.

Brevo's free plan is measured in sending volume (up to 300 emails a day, with no contact ceiling that matters at small size), while Mailchimp's free plan is measured in contacts (250 of them) and pauses sending when you pass the limit. In Europe, Brevo's paid tiers start lower on the page (Starter at EUR 7/month, Standard at EUR 15/month billed monthly) and bundle SMS, WhatsApp, chat and a CRM into the same subscription; Mailchimp's Essentials starts at EUR 11.50/month and its strength is the paid ladder above it, where automation, testing and reporting get noticeably deeper. Pick Brevo when channel breadth and per-send cost decide it. Pick Mailchimp when you want the more mature campaign, automation and reporting toolset and are willing to pay for it.
