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.

This comparison covers what matters in daily use. For the broader email marketing picture, see our Brevo vs Mailchimp comparison and the Brevo full-funnel deep dive.

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 $9/month entry tier, the comparison is nuanced. MailerLite Growing Business charges $9/month for up to 500 subscribers (scaling to $19/month for 2,500 subscribers and higher as your list grows). Brevo Starter charges $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.

At 5,000 subscribers, MailerLite Growing Business costs $39/month. Brevo Starter at $9/month covers 5,000 emails to those 5,000 contacts — so if you send one campaign per month to your whole list, Brevo is dramatically cheaper. If you send weekly campaigns, you need a higher Brevo volume tier, which narrows the gap.

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 does not currently offer an in-editor AI writing tool.

For landing pages, both tools are comparable. MailerLite includes a landing page builder with all paid plans and offers a website builder with up to 10 pages on free plans. Brevo includes a landing page builder on Business plans and above. 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 more powerful at the feature level but harder to build. It supports transactional triggers (purchase confirmations, password resets), website behavior triggers (page visits, events fired via JavaScript), and marketing triggers (form submissions, tag changes). The combination of marketing and transactional automation in one platform is Brevo's strongest differentiator — if you send both newsletters and order confirmations, you can consolidate both into one tool. MailerLite does not handle transactional email.

Brevo also includes SMS and WhatsApp messaging as part of the same automation workflow. You can build a sequence that sends an email, then an SMS two days later, then an email follow-up. For agencies in markets where SMS outreach is normal (sales follow-up, appointment reminders), this multi-channel capability is something MailerLite simply cannot match.

Deliverability is difficult to test objectively without a controlled experiment. Both MailerLite and Brevo have good reputations for inbox placement among small senders. Neither has had major blacklisting issues reported at scale.

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's infrastructure is built around transactional email as a core use case. It maintains a strong reputation among developers and SaaS companies for transactional deliverability. For marketing campaigns, Brevo's deliverability is comparable to MailerLite. A dedicated IP is available on Enterprise plans.

On analytics, Brevo Business includes more advanced reporting — heat maps, click maps, send-time optimization, and A/B testing. 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 1,000 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 a few thousand contacts, 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.
