Brevo is a strong fit when sending volume matters more than list size and you may need transactional messaging. MailerLite is a straightforward newsletter choice for a small list. Kit is designed around creator growth and products. Mailchimp remains a broad marketing suite but its current free allowance is small. Choose by subscriber count, monthly sends, automation and consent—not by the largest advertised free number.
- Best for
- Freelancers and creators starting with an explicit-consent list, a defined newsletter cadence and a documented upgrade budget.
- Not suitable for
- Purchased lists, scraped addresses, cold bulk outreach or anyone expecting a tool to replace consent, sender authentication and useful content.
- Bottom line
- Start free with one welcome flow, but calculate the paid tier at your expected list and send frequency before importing contacts.
- Brevo primarily tiers by email volume and contact capacity; MailerLite, Kit and Mailchimp use subscriber or contact counts more directly.
- A free plan can stop sending when a contact, subscriber or email limit is exceeded, so record the exact trigger.
- Double opt-in is useful evidence and list-quality protection, but legal compliance still depends on jurisdiction and purpose.
- These recommendations are non-affiliate and based on official documentation, not deliverability or support testing.

Brevo: best when send volume drives the budget
Brevo's official plan guide checked on 2026-08-01 listed Free at $0 with 300 daily email sends, up to 100,000 stored contacts and automation for up to 2,000 contacts. Starter began at $9 monthly and Standard at $18 monthly in the US reference guide, with tiers based on monthly sends and stored contacts.
This can fit a freelancer with a larger low-frequency contact database because send volume is a central pricing input. Brevo also combines marketing and transactional messaging. However, the Free daily cap can make a single newsletter take multiple days, and automation scope differs by plan.
Brevo offers full-page, embedded and pop-up forms, double opt-in and consent fields. Our consent-based Brevo setup guide explains the safe workflow.
Best for: a service business sending scheduled campaigns and transactional messages from one account.
Watch: daily sends, stored-contact tier, automation contacts, logo removal, landing pages and the exact paid upgrade.
MailerLite: best straightforward newsletter starting point
MailerLite's pricing page checked on 2026-08-01 listed Free for up to 250 active subscribers and 2,500 monthly emails, with campaigns, forms, landing pages and limited automations. Comfort started at $12 monthly and Power at $25 for the smallest displayed tier, with subscriber-based scaling and different send/feature limits.
The product is attractive when the main job is collecting subscribers, sending a newsletter and running a small welcome flow. MailerLite says free sending locks if active subscribers exceed the plan limit. Paid-plan billing uses active subscribers and can move to a higher tier as the list grows.
Best for: a small publication or freelancer wanting conventional list, form and automation tools.
Watch: active subscriber counting, automation limits, monthly sends and the cost at your expected next subscriber tier.

Kit: best for creator-led newsletters and products
Kit's official help center says its Newsletter plan supports up to 10,000 active unique subscribers, unlimited forms and landing pages, unlimited sends, one basic visual automation and one email sequence. The free economics include one Kit-managed Recommendation slot whose paid-recommendation earnings go to Kit.
Paid Creator and Creator Pro plans remove that particular starting limitation and add broader automation or reporting. The current official comparison listed Creator from $39 monthly and Creator Pro from $79 for up to 1,000 subscribers, with pricing scaling by subscriber count.
Best for: creators who want a newsletter, public feed, recommendations and digital-product tools in one system.
Watch: the managed recommendation slot, paid-plan jump, subscriber tiers and which automation/reporting features require upgrade.
Mailchimp: best for a broad familiar suite, not the largest free plan
Mailchimp's current pricing page listed Free for up to 250 contacts with 500 monthly sends and a 250-send daily limit. Standard and Essentials had time-limited trials and contact-based paid tiers. Mailchimp includes broader campaign, audience and marketing features, but the free ceiling is now suited to evaluation rather than a growing publication.
Best for: a business already using Mailchimp integrations or needing its wider marketing ecosystem.
Watch: billable contact rules, send multipliers, seats, audiences, feature gates and the price after trial or introductory terms.
How to choose with real numbers
Create a twelve-month sheet with:
- starting subscribers;
- expected monthly net growth;
- newsletters per month;
- automation messages per subscriber;
- separate transactional volume;
- required seats and domains;
- the first three paid tiers you could reach;
- taxes and annual commitment;
- migration and setup time.
For example, 800 subscribers receiving four newsletters and two automated messages can require 4,800 sends before tests, resends or transactional email. A large contact allowance does not help if the send cap is the bottleneck; unlimited sends do not help if subscriber pricing becomes the bottleneck.
Consent and deliverability basics
No platform guarantees inbox placement. Use an authenticated sending domain, clear consent, honest sender identity, a visible unsubscribe link and consistent content. Remove hard bounces and respect unsubscribes across every list and automation.
Double opt-in adds a confirmation step and can help prevent typo or bot addresses. It is not a universal legal requirement or a complete compliance program. Keep the form language, timestamp, source, privacy notice and consent purpose.
Do not import a LinkedIn contact list, purchased list or scraped addresses simply because the software accepts CSV files.
Limitations
UseAIVisora did not send a campaign, test editors, measure deliverability, build automations, contact support or inspect billing for these tools. Official free limits and prices can change. Inbox placement depends on sender reputation, authentication, content, list quality and recipient providers—not only software choice.
Frequently asked questions
Frequently asked questions
What is the best free email marketing tool?
It depends on the constraint. Brevo emphasizes daily send volume, MailerLite a small active-subscriber allowance, Kit creator-oriented scale with a managed recommendation slot, and Mailchimp a small broad-suite evaluation tier.
Is Brevo or MailerLite better for freelancers?
Brevo can fit send-volume and transactional needs; MailerLite can fit a simpler newsletter workflow. Price the expected list and monthly sends on both.
Do I need double opt-in?
Requirements vary, but double opt-in can provide useful confirmation and reduce invalid signups. It does not replace legal advice, clear form language or privacy records.
Can I email my professional network without consent?
Do not assume a connection, business card or public email permits bulk marketing. Determine the lawful basis and platform rules for the recipient and jurisdiction.
Were these tools tested for deliverability?
No. The comparison uses official sources checked on 2026-08-01 and makes no deliverability, editor, automation, billing or support claim.
