MailerLite vs Brevo for Solo Agency Email Marketing (2026)

The budget email marketing space used to be dominated by Mailchimp. That changed when Mailchimp raised prices significantly and tightened its free plan. MailerLite and Brevo both grew by capturing teams that were looking for a credible alternative. Now they compete directly with each other.

MailerLite built its reputation on simplicity. The interface is clean and direct, the automation builder is visual and easy to learn, and the pricing has been consistently transparent. For a solo agency founder who needs to send a newsletter, run a nurture sequence, and not think too hard about deliverability, MailerLite removes friction.

Brevo (formerly Sendinblue) took a different route. It expanded aggressively into multi-channel marketing — email, SMS, WhatsApp, transactional email, and a built-in CRM. The result is a platform with more surface area, lower per-email cost, and a more complex pricing model. For an agency that wants to handle outreach, client communication, and marketing from a single tool, Brevo can replace two or three separate subscriptions.

Pricing and free-plan details below were verified on April 1, 2026 from official MailerLite and Brevo pricing and help pages.

Both tools charge based on different models. MailerLite charges based on subscriber count. Brevo charges based on email volume sent per month, with unlimited contacts on all plans. This difference has real implications depending on your list size and sending frequency.

At the entry tier, the comparison is nuanced. MailerLite Growing Business starts at $10/month for up to 500 subscribers (scaling upward as your list grows). Brevo Starter starts at $9/month for 5,000 emails per month regardless of contact count. If you have a large list but send infrequently, Brevo is cheaper. If you have a small list and send frequently, MailerLite is more predictable.

That means the real comparison is list size versus send frequency. MailerLite gets more expensive as your subscriber count grows, but the bill stays easy to predict when you email often. Brevo stays cheaper for large lists with light send volume, then gets more expensive as you add campaigns, automation, and higher monthly send tiers.

MailerLite's drag-and-drop email editor is one of the cleanest in the industry. The block system is intuitive, templates are professionally designed, and the preview mode accurately reflects how emails render across clients. For a solo founder who wants to send polished campaigns without hiring a designer, MailerLite's builder is faster and more pleasant to use than most alternatives.

Brevo's email builder has improved significantly in recent versions but still feels less refined than MailerLite's. The drag-and-drop blocks work well, the template library is adequate, and the HTML editor is available on paid plans. It is functional and gets the job done, but it does not feel as considered as MailerLite's experience.

Both tools support mobile-responsive templates, conditional content blocks (show different content to different segments), and personalization tokens. MailerLite Advanced includes an AI writing assistant for email copy generation. Brevo now offers AI-assisted copy features too, but MailerLite's editor still feels more focused if your main job is shipping straightforward newsletter campaigns.

For landing pages, both tools are comparable. MailerLite includes a landing page builder with all plans and offers up to 10 landing pages on the free tier. Brevo includes 1 landing page on Standard and expands that on higher plans. If landing pages are important to your funnel, MailerLite's included landing page builder is a meaningful advantage over Brevo Starter.

Automation is where the choice often gets made for solo agencies that run nurture sequences or onboarding flows for new clients.

MailerLite's automation builder is visual and workflow-based. You drag and drop triggers, conditions, and actions to build sequences. The interface is clear enough that a non-technical founder can build a multi-step welcome sequence in under an hour. Automation is included on the free plan, which makes it one of the most accessible automation builders in this price range. You can trigger automations on form submissions, tag additions, date-based events, and purchase activity (with e-commerce integrations).

Brevo's automation is broader at the platform level but harder to learn. The big difference is that Brevo combines campaign automation with transactional email and CRM data in the same account. If you want newsletters, follow-up sequences, and system-triggered messages inside one stack, Brevo has a real advantage. MailerLite does not handle transactional email.

Brevo also supports SMS across plans and adds WhatsApp campaigns on higher tiers. For agencies where text-message follow-up or a broader customer-communication stack matters, that channel mix is a real differentiator. If email is the whole job, MailerLite stays simpler.

Deliverability is difficult to compare objectively without controlled tests on the same list, domain, and sending habits. The more useful published differences here are infrastructure controls and reporting, not broad inbox-placement claims.

MailerLite uses shared IP addresses on standard plans. A dedicated IP is available on Enterprise plans, which gives high-volume senders more control over sender reputation. For most small agencies sending under 50,000 emails per month, shared infrastructure from a reputable provider is adequate.

Brevo also supports transactional email, which matters if the same platform needs to handle both campaigns and system-triggered messages. A dedicated IP is available as an add-on on Professional and Enterprise plans.

On analytics, Brevo Standard includes advanced reports, A/B testing, and AI send-time optimization. Professional adds Analytics Studio dashboards and deeper segmentation controls. MailerLite Advanced includes A/B testing and click maps but charges for advanced automation features. For most solo agencies, the default open rate, click rate, and unsubscribe tracking available on both tools' base paid plans is sufficient.

Choose MailerLite if:

• You want the cleanest email builder and fastest learning curve for non-technical users.
• You have a small list (under 500 subscribers) and want automation on a free plan.
• You send regular newsletters and want a landing page builder included without paying extra.
• You want an AI writing assistant to speed up email copy creation.
• You send primarily email and do not need SMS or WhatsApp outreach.

Choose Brevo if:

• You have a large contact list but send infrequently — Brevo's volume-based pricing is cheaper at scale.
• You want SMS and email in one platform for multi-channel follow-up sequences.
• You also send transactional email (order confirmations, notifications) and want one tool for both.
• You want a built-in CRM alongside email marketing without paying for a separate tool.
• Budget control matters and you want predictable pricing based on send volume, not list size.

For most solo agency founders whose primary channel is email newsletters and nurture sequences, MailerLite is the better starting point. The free plan is genuinely usable, the builder is the most intuitive in this price range, and the paid tiers are fair. If you are starting fresh with an email list under 500 subscribers, MailerLite removes friction.

Brevo earns the recommendation when your use case expands beyond clean email sending. If you want SMS in the same workflow, need transactional email, have a large contact list you send to infrequently, or want a built-in CRM alongside your email tool, Brevo consolidates tools in a way MailerLite does not. The Brevo full-funnel deep dive covers what a consolidated Brevo setup actually looks like.

Both beat Mailchimp on price for small teams. Neither is the right choice for high-volume performance marketing — at that scale, dedicated deliverability-first platforms matter more.
