Options to examine by operating model

Base cost primarily on sending volume

Brevo documents up to 300 emails per day on Free and offers monthly or annual subscriptions plus pay-as-you-go credits. Its structure is useful when send volume matters more than the stored contact count.

Start with a very small list

MailerLite Free officially includes 250 active subscribers, 2,500 emails per 30 days and two users, together with limited forms, landing pages and automations.

Run a creator newsletter and digital products

Kit offers a free Newsletter plan. Its detailed comparison lists up to 10,000 active subscribers, unlimited forms, landing pages and broadcasts, and one basic automation.

Combine advanced automation and ecommerce

GetResponse Starter includes unlimited monthly sends and one workflow, while Marketer documents unlimited workflows, advanced segmentation and abandoned-cart recovery.

Eight points to verify before implementation

01

Billable metric

Identify whether cost rises with stored contacts, active subscribers, monthly sends or a combination.

02

What happens at the free limit

Check whether sending is blocked, the account is automatically upgraded or overage fees are billed.

03

Automation scope

Review welcome messages, branching, tags, purchase or page events and abandoned-cart workflows by plan.

04

Forms and pages

Compare embedded forms, popups, custom domains, page counts and visitor limits.

05

Marketing versus transactional

Confirm whether campaigns and order confirmations or password resets are covered by the same product and price.

06

Users and permissions

Review seats, approvals, administrator roles and added-user charges.

07

Domain authentication

Check custom domains, SPF, DKIM, DMARC, sender verification and dedicated-IP conditions.

08

Migration and export

Confirm whether contacts, tags, segments, templates and delivery history can be imported and exported.

Official information for each service

Mailchimp

Mailchimp offers four Marketing plans: Free, Essentials, Standard and Premium. Billing depends on the plan, stored-contact tier and monthly sending allowance rather than the plan name alone.

  • The official pricing page lists the Free sending cap as 500 per month or 250 per day
  • Essentials, Standard and Premium differ in features and sending multiples
  • Infrequent senders can purchase email credits instead of a monthly or annual marketing plan
  • Paid accounts may be billed for overages when contact or sending limits are reached

Check: Compare the contact tier, send multiple, users, automation functions and overage rules together.

Brevo

Brevo combines email, SMS, WhatsApp, automation, CRM and transactional messaging. Its official Marketing Platform page documents a Free plan of up to 300 emails per day.

  • Free allows up to 300 emails per day and requires no card
  • Brevo states that all plans provide access to transactional-email features
  • Monthly and annual commitments are available, together with pay-as-you-go credits
  • The model is relatively easy to compare by sending volume

Check: Review the daily cap, monthly volume, Brevo branding, dedicated IP and country-specific SMS or WhatsApp costs.

MailerLite

MailerLite offers Free, Comfort, Power and Enterprise. The Free plan was revised in June 2026 and officially lists 250 active subscribers, 2,500 emails per 30 days and two users.

  • Free: 250 active subscribers, 2,500 emails and two users
  • Free includes three automations, three forms, one website and one landing page
  • The official Free page shows Comfort from $12 per month and Power from $25
  • Paid accounts may automatically move to the next tier when active subscribers exceed the current ceiling

Check: Subscriber counting is cumulative within a billing cycle, so deleting contacts may not reduce the current cycle's counted total immediately.

Kit

Kit combines newsletters, forms, landing pages, automations and sales of digital products or paid newsletters. Its plans are Newsletter, Creator and Creator Pro.

  • The detailed plan table lists up to 10,000 active subscribers on the free Newsletter plan
  • Newsletter includes one basic Visual Automation and unlimited forms, landing pages and broadcasts
  • At up to 1,000 subscribers, Creator starts at $39 per month and Creator Pro at $79 per month; annual billing includes two months free
  • Creator adds unlimited automations and sequences; Pro adds analytics and unlimited users

Check: Paid prices scale with subscriber count, so model both the current list and the expected list one year later.

GetResponse

GetResponse packages email, forms, landing pages, automation, ecommerce, web push and website or course functions by plan. Its 14-day premium trial does not require a card.

  • At the 1,000-contact selection, Starter is $19 monthly or $15.58 on annual billing
  • Starter includes unlimited monthly sends, one workflow, forms, popups and landing pages
  • Marketer is $59 monthly or $48.38 annual-equivalent and adds unlimited workflows and ecommerce functions
  • Annual plans advertise a free custom domain for one year

Check: Price scales with list size. Separate the single-workflow Starter requirement from the advanced automation and ecommerce functions in Marketer.

How to narrow the list by use case

Send a regular newsletter to a small list

Compare MailerLite, Brevo and Mailchimp by the actual monthly send requirement, not only by the subscriber ceiling. Weekly and daily schedules produce very different totals.

Sell newsletters, courses or digital products

Compare Kit and GetResponse on subscriptions, products, courses, landing pages, automation and transaction fees.

Automate ecommerce behaviour

Review GetResponse, Mailchimp and Brevo for abandoned carts, purchase data, revenue reporting, ecommerce integrations and the contractual scope of transactional messages.

Store many contacts but send infrequently

Contact-based and volume-based pricing can produce different totals. Model Brevo's send-volume approach against the contact or list tiers of Mailchimp, MailerLite, Kit and GetResponse.

Operational checks before sending

  • Add only recipients with a valid consent or other lawful basis; do not use unclear purchased or scraped lists
  • Verify unsubscribe links, sender identification and the privacy policy
  • Configure SPF, DKIM and DMARC for the sending domain and verify authentication in test messages
  • Retain the acquisition source, consent timestamp and unsubscribe history
  • Enable multi-factor authentication for administrators and remove unnecessary access

Legal requirements vary by recipient country, region and message type. This article is not legal advice; consult official compliance material and qualified advisers where required.

Frequently asked questions

Can a small business start with a free plan?

Yes, but free plans limit contacts, sends, automation, branding, support or page counts. Calculate the required monthly sends from the expected list and schedule first.

Should I prioritise contact count or sending volume?

Large lists with infrequent campaigns may benefit from volume-based pricing. Small lists with frequent messages need to examine send multiples or unlimited-send conditions.

Are marketing and transactional emails the same?

No. Newsletters and promotions are marketing messages, while order confirmations and password resets are transactional. Some platforms price or operate them separately.

Is custom-domain authentication necessary?

To manage deliverability and sender trust, follow the platform's official instructions for SPF, DKIM and DMARC where supported.
