Marketing Email Tools Compared: Alternatives, Pricing and Fit
Ten mainstream marketing email platforms compared by best-fit audience, entry price, list-size costs, and the limits to check before you commit.
For most small teams that are just starting, MailerLite is the best first pick in this group. Its free plan covers up to 250 subscribers and 2,500 emails a month, and the first paid step, Comfort, costs $12 a month on monthly billing for the 500-subscriber tier ($10.80 a month if you pay yearly). That combination lets you run a real newsletter or welcome sequence before any money changes hands, and it keeps the move to a paid plan predictable.
Marketing email platforms are priced on different units: contacts or profiles, emails sent, seats, or a mix of these. The same list can cost very different amounts from one vendor to the next, so this page compares plans by the list sizes that matter. Prices below are taken from each vendor's public pricing page as read on October 7, 2026. Treat them as starting points, confirm them on the linked page before you sign, and recalculate at the list size you expect in twelve months.
How to read this shortlist
The ten tools fall into three groups. Newsletter and general-purpose platforms (MailerLite, Kit, Mailchimp, Brevo) suit teams that send scheduled campaigns and simple automations. Commerce platforms (Klaviyo, Omnisend, Drip) build their workflows around orders, carts and product data. Lifecycle and CRM platforms (Customer.io, ActiveCampaign, HubSpot Marketing Hub) fit teams whose messages depend on product events, sales stages or a shared contact record. A tool can be the right choice in one group and a poor one in another, so start with the group that matches your work.

What the plans cost at three list sizes
The table below shows the plan named on each vendor's page at 500, 5,000 and 10,000 contacts or profiles. Where the vendor's published figures do not cover a size, the cell says "Pricing on request" rather than an estimate. Ask the vendor for a quote at that size before you rely on the number.
| Tool | About 500 contacts | About 5,000 contacts | About 10,000 contacts |
|---|---|---|---|
| MailerLite | Comfort, $12/mo monthly ($10.80/mo billed yearly) | Pricing on request | Pricing on request |
| Kit | Free, $0 | Free, $0 | Free, $0; Creator from $33/mo billed annually for sequences |
| Mailchimp | Standard, $20/mo monthly | $100/mo monthly (2,501 to 5,000 contact band) | $135/mo monthly (5,001 to 10,000 contact band) |
| Brevo | Free, with 300 sends a day | Free, with 300 sends a day | Free, with 300 sends a day |
| Klaviyo | Email plan, $20/mo monthly (500 profiles) | Email plan, $100/mo monthly (5,000 profiles) | Email plan, $150/mo monthly (10,000 profiles) |
| Omnisend | Standard, $11.20/mo (500 contacts; displayed rate includes a first-three-month offer) | Pricing on request | Pricing on request |
| Drip | $39/mo monthly (1 to 2,500 people) | $89/mo monthly (4,501 to 5,000 people) | $154/mo monthly (9,001 to 10,000 people) |
| ActiveCampaign | Pricing on request (Starter starts at 1,000 contacts) | Pricing on request | Pricing on request |
| HubSpot Marketing Hub | Starter from $7/mo; seat-based | Pricing on request | Pricing on request |
| Customer.io | Essentials from $100/mo monthly | Pricing on request | Essentials 10k profiles, $145/mo monthly |
Two calculations are worth doing on the vendor's page. First, check the cost at the next list-size band, not only the current one, because several tools change price sharply at a threshold. Second, multiply by 12 for the yearly figure: for example, 12 × $11.20 is $134.40 for a first year that includes an introductory offer, and the rate after that offer ends can be higher, so read the terms before you assume the saving continues.
MailerLite
Best for: Small businesses, creators and nonprofits that send newsletters, opt-in forms and simple welcome sequences. The interface is built for people who do not want to maintain a data model.
What it does well: The free plan is generous for a small list, and the editor and landing-page tools keep launch work in one place. A new team can have a signup form, a welcome flow and a broadcast running quickly.
Where it falls short: Complex branching based on product events, deep custom data models and advanced permission structures are not the core of the product. Teams that outgrow the simple model often move to Customer.io or ActiveCampaign.
Price: Free for up to 250 subscribers and 2,500 emails a month. Comfort is $12 a month on monthly billing for the 500-subscriber tier, or $10.80 a month billed yearly. Check the MailerLite pricing page for current tiers above 500 subscribers.
Kit
Best for: Writers, course creators and independent publishers whose work is organised around broadcasts, tags and subscriber relationships. It suits a business where the audience is the product.
What it does well: The free plan includes unlimited landing pages, forms and email broadcasts, plus tagging and segmentation, for up to 10,000 subscribers. Selling digital products and subscriptions is part of the same platform.
Where it falls short: Visual automations and unlimited email sequences start on the Creator plan. If your messages depend on application events or detailed product telemetry, you will need another system feeding the list.
Price: Free for up to 10,000 subscribers. Creator is $33 a month billed annually and adds unlimited Visual Automations and sequences. Kit offers a 14-day free trial on paid plans without a credit card. See the Kit pricing page for Pro, which is $66 a month billed annually.
Mailchimp
Best for: General campaign teams that value a familiar editor, a long list of integrations and a shared place for conventional campaigns and basic automations.
What it does well: Training costs are low because many marketers already know the editor. The integration catalogue is broad, which helps when your website, shop or CRM is not a single vendor.
Where it falls short: Contact tiers climb steeply as the list grows, and each tier also sets an email allowance. Feature gates can push a team onto a higher plan than the base price suggests, so model the tier you will need at your next milestone.
Price: The free plan covers up to 250 contacts and 500 sends a month. Standard starts at $20 a month on monthly billing for 500 contacts. At 5,000 contacts the listed band is $100 a month, and at 10,000 the band is $135 a month. Confirm on the Mailchimp pricing page.
Brevo
Best for: Teams with a large list that is mailed infrequently, and teams that want campaigns and transactional messages under one vendor. Brevo prices by monthly send volume, not only by contacts, which can favour a big list with light usage.
What it does well: The free plan allows up to 100,000 contacts, and it is a useful way to test a large database before committing. Combining marketing and transactional messages can reduce the number of vendors you manage.
Where it falls short: The free plan is capped at 300 sends a day, which rules it out for frequent campaigns. SMS is charged separately, and automation depth and seat limits should be checked before you rely on them.
Price: Free with 300 sends a day. Starter is $9 a month on monthly billing for 5,000 emails a month, with no daily cap. Standard, at $18 a month, adds automation, A/B testing and advanced reports. See the Brevo pricing page for the current volume bands.
Klaviyo
Best for: Ecommerce brands whose messages depend on orders, carts, catalogues and customer value. Its strength is purchase-aware segmentation, which works best when store data is clean.
What it does well: Commerce integrations and behavioural segments let a store send abandoned-cart, post-purchase and win-back flows that respond to what customers actually bought.
Where it falls short: Profile count drives the bill, and optional channels such as SMS add cost. A non-commerce team pays for commerce features it may not use, so Klaviyo is harder to justify outside retail.
Price: Free for up to 250 active profiles and 500 email sends a month. The Email plan is $20 a month for 500 profiles, $60 for 2,500, $100 for 5,000, $150 for 10,000 and $400 for 25,000, all billed monthly. The Klaviyo pricing page lists the combined Email and SMS plans separately.
Omnisend
Best for: Small and mid-sized ecommerce stores that want ready-made store journeys with email and optional SMS in one tool.
What it does well: Commerce templates and cross-channel workflows can shorten the time to a first live automation. For a store that wants email and SMS together, the setup is more direct than assembling two vendors.
Where it falls short: Store-specific behaviour, coupon logic and SMS economics need checking against your own store before launch. Pricing at larger contact counts is not shown on the plans used here, so ask for a quote at that size.
Price: Free for up to 250 contacts, 500 emails and 500 web push notifications a month. Standard is $11.20 a month for 500 contacts and 6,000 emails, with the displayed rate including a 30% introductory offer for the first three months. Pro is $41.30 a month for 2,500 contacts with unlimited emails. Check the Omnisend pricing page for the rate after the offer ends.
Drip
Best for: Ecommerce teams that want campaigns and workflows built around store behaviour, where product, order and revenue data matter more than a general newsletter editor.
What it does well: A commerce-first model makes repeat-purchase and segmentation workflows easier to reason about. Unlimited email sends are included on the people-based plans.
Where it falls short: If your business has no meaningful store data, the commerce focus adds little. There is no ongoing free plan, only a 14-day trial with no credit card required.
Price: $39 a month for 1 to 2,500 people, $89 for 4,501 to 5,000 people and $154 for 9,001 to 10,000 people, billed monthly. See the Drip pricing page for bands in between.
ActiveCampaign
Best for: Teams that combine CRM context, lead scoring and sophisticated branching, where marketing automation has to hand off to sales with a shared contact record.
What it does well: Automation depth and sales handoff can replace several disconnected tools. Branching based on deal stage, tags and behaviour is the reason teams choose it.
Where it falls short: Plan complexity and the learning curve are real. Contact pricing, seats and feature tiers all need one owner who understands them before the first invoice.
Price: There is a free trial. Starter is $15 a month starting at 1,000 contacts, and the figure is the same whether you bill monthly or annually. Plus, Pro and Enterprise start at $49, $79 and $145 a month at the same 1,000-contact starting point. Model the live plan on the ActiveCampaign pricing page.
HubSpot Marketing Hub
Best for: B2B teams already invested in HubSpot CRM that want shared contact, company, deal and campaign records in one governed system.
What it does well: Shared CRM data reduces handoff confusion between marketing and sales. Reporting across the funnel is one of the main reasons organisations buy into the platform.
Where it falls short: Costs rise quickly with hub tiers, contact limits and seats. A small team that only needs newsletters will pay for capability it does not use.
Price: Free marketing tools are available. Starter is listed from $7 a month, Professional at $800 a month and Enterprise at $3,600 a month, with the plans priced per seat. Confirm the seat count and what each tier includes on the HubSpot Marketing Hub pricing page.
Customer.io
Best for: Product teams whose messages depend on events, user attributes and lifecycle state, such as trial activation, feature adoption, downgrades and deletion events.
What it does well: Event-driven journeys and multi-channel orchestration are its main strengths. It supports the kind of logic that list-based newsletter tools cannot express.
Where it falls short: The setup is more involved, and the team must keep event data accurate. Identity merges, frequency limits and suppression all need deliberate design, which means more engineering time than a newsletter tool.
Price: Essentials starts at $100 a month on monthly billing and includes the visual workflow builder and basic data integrations. Profile-based Essentials tiers include $145 a month at 10,000 profiles, $235 at 20,000 and $325 at 30,000. Eligible early-stage companies that have raised under $10 million can receive 12 months free through the Startup Program. See the Customer.io pricing page for the current terms.
Choosing by job, not by brand
The fastest way to narrow the list is to name the one job the tool must do in the next six months. A newsletter team and a SaaS company with billing events have different needs, and the same tool can be ideal for one and wrong for the other. The table below maps common situations to a starting pick and gives the reason. It is a starting point for a pilot, not a final decision.
| If you need | Start with | Because |
|---|---|---|
| A free start for a small list | MailerLite | The free plan covers 250 subscribers and 2,500 emails a month |
| Newsletters and digital products | Kit | The free plan includes unlimited broadcasts for up to 10,000 subscribers |
| Purchase-aware store flows | Klaviyo or Omnisend | Both build flows from order and cart data; check profile or contact growth |
| Event-driven product messages | Customer.io | Journeys respond to events and attributes, not only list membership |
| CRM handoff and deep branching | ActiveCampaign or HubSpot Marketing Hub | Both share contact and deal context with sales, priced by contacts or seats |
| A large list mailed rarely | Brevo | Volume-based pricing suits a big list that is not sent often |
| Application receipts and alerts | A sending API such as Resend or Postmark | Transactional streams are separate from marketing campaigns; Resend's free plan allows 3,000 emails a month, Postmark's allows 100 |
How to choose between the finalists
Start by writing down your list size today and the size you expect in a year. Then read the pricing page for each finalist and find the plan that covers both. A tool that looks cheapest today can become the most expensive at the next band, so the second number matters more than the first.
Next, decide where your messages come from. If they come from a store, check whether the platform reads orders and carts directly. If they come from product events, check whether it accepts the events you already track. If they come from a schedule and a list, a simpler tool will usually cost less and take less time to run.
Finally, check the exit path. Ask whether you can export contacts, consent records, tags, fields, templates and suppression lists in a usable format. A tool that is hard to leave is expensive even when the monthly price is low.
Setup and migration checklist
Moving to a new platform is easier when the old list is clean. Before you import anything, remove hard bounces, confirm the consent source for each contact, and make sure unsubscribes are honoured in the new system. The table below lists the steps that most often cause problems.
| Step | What to do | Check before you cut over |
|---|---|---|
| 1. Export | Download contacts, tags, fields and suppression lists from the current tool | Row counts match the source, and suppressed addresses are included |
| 2. Clean | Remove hard bounces and duplicate records | Each contact still has a recorded consent source |
| 3. Authenticate | Set up SPF, DKIM and DMARC for your sending domain in the new tool | Test sends pass authentication on both the old and new sending domains |
| 4. Import | Load contacts with their suppression status intact | Unsubscribed and complained addresses stay suppressed after import |
| 5. Rebuild | Recreate the top three campaigns and automations, not every old flow | Trigger and branch logic match the original in a test account |
| 6. Run in parallel | Send to a small segment from both tools for one or two cycles | Open, click and bounce rates are read from the same definitions |
| 7. Cut over | Switch forms, integrations and the sending domain to the new tool | Old automations are paused so no contact receives duplicates |
A pilot should prove more than the interface. Build one real campaign, one automation that starts from a live event or a form, and one suppression test, then check the results. Keep the evidence, because the decision memo is what your team will read when someone asks why you chose a tool.

Frequently asked questions
Which marketing email tool should I start with on a small budget?
MailerLite is the most practical first choice for a small list. Its free plan covers up to 250 subscribers and 2,500 emails a month, and the first paid tier, Comfort, is $12 a month on monthly billing for the 500-subscriber tier. Kit is also free up to 10,000 subscribers, which makes it a good choice if your work is publishing rather than automation.
Why do prices differ so much at the same contact count?
Vendors count different things. Some charge by contacts, some by profiles that have been active recently, some by emails sent and some by seats. A list of 5,000 people can be a $100 monthly bill on one platform and a much smaller or larger figure on another, depending on how the platform defines a contact and how many messages you send.
Do I need a separate tool for transactional email?
In most cases, yes. Receipts, password resets and application alerts are better handled by a sending API that is built for reliability and per-message logging. Resend offers a free plan of 3,000 emails a month and Postmark a free plan of 100 emails a month. Amazon SES charges $0.16 per 1,000 emails at the entry band, but you must manage more of the setup yourself.
Can Customer.io be free for an early-stage startup?
It can be, if you qualify. Customer.io's Startup Program offers 12 months free to eligible early-stage companies that have raised under $10 million. Eligibility is set by the vendor, so read the terms on the Customer.io pricing page before you plan around it.
How do I move my list without losing consent records?
Export the consent source, timestamp and suppression status for every contact before you leave the current tool. Import those fields into the new platform, and confirm that unsubscribed and complained addresses stay suppressed. If a tool cannot store consent source or suppression status, treat that as a serious limitation rather than a cosmetic one.
Are the prices on this page final?
No. Each price was read from the vendor's public pricing page on October 7, 2026. Vendors change plans, introductory offers and band sizes without notice. Check the linked pricing page on the day you decide, and ask for a quote at your expected list size where the page does not show one.
Which tool suits a SaaS team that sends messages based on billing events?
Customer.io is the strongest match in this list because its journeys respond to events and attributes such as trial start, plan change and failed payment. Set up event tracking first and confirm that identity merges and suppression work in a test account. ActiveCampaign is a good alternative if the same team also needs CRM branching and sales handoff.
