Overview

Constant Contact and Brevo represent different approaches to email marketing. Constant Contact is an established platform with event marketing and strong support. Brevo (formerly Sendinblue) is an all-in-one suite with email, SMS, and transactional capabilities.

Dramatic Price Difference

Brevo is dramatically cheaper - $25/month vs $80/month for 10k contacts. That's 69% savings. Brevo's email-based pricing model can offer exceptional value for large lists with moderate sending frequency.

Multi-Channel Marketing

Brevo offers email, SMS, WhatsApp, and transactional email from one platform. Constant Contact is focused on email marketing. For unified multi-channel campaigns, Brevo is comprehensive.

Event Marketing

Constant Contact includes event management with registration, ticketing, and follow-ups. Brevo has no event features. If you run events, Constant Contact provides built-in tools.

Support Comparison

Constant Contact offers phone support - you can call and talk to someone. Brevo provides chat and email support only. For businesses that value phone access, Constant Contact wins.

Transactional Email

Brevo handles both marketing and transactional email from one platform with a unified API. Constant Contact is marketing-only. For development teams needing both, Brevo simplifies the stack.

For SaaS Companies

Neither platform offers native Stripe integration for subscription automation. Brevo has better transactional email but lacks SaaS-specific features. For SaaS companies, consider Sequenzy which offers purpose-built SaaS automation.

Making the Choice

Choose Constant Contact for event marketing and phone support. Choose Brevo for multi-channel marketing and significant cost savings. For SaaS, consider Sequenzy.

Automation Capabilities Compared

Brevo's automation has evolved significantly since its Sendinblue days. You get multi-step workflows with conditional branching, send time optimization, and the ability to trigger automations based on page visits, email engagement, and purchase behavior. The workflow builder is visual and intuitive, making it accessible to non-technical marketers who want sophisticated campaigns.

Constant Contact's automation is more straightforward — welcome sequences, birthday emails, and basic drip campaigns. While reliable for simple use cases, it lacks the conditional logic and behavioral triggers that modern marketing demands. If you need to send different follow-up sequences based on which links a subscriber clicked, Brevo handles this natively while Constant Contact requires manual workarounds.

WhatsApp and Conversational Marketing

One of Brevo's standout features is built-in WhatsApp marketing — something Constant Contact does not offer at all. For businesses with international customers, particularly in Europe, Latin America, and parts of Asia, WhatsApp open rates regularly exceed 90%. Brevo lets you send promotional messages, order updates, and even run WhatsApp automations from the same platform you use for email.

This multi-channel approach extends to live chat as well. Brevo includes a website chat widget that feeds conversations into the same CRM where your email contacts live. This unified view of customer interactions across email, SMS, WhatsApp, and chat is something Constant Contact simply cannot match, regardless of which plan you choose.

Deliverability and Reputation Management

Both platforms have invested in deliverability infrastructure, but they take different approaches. Constant Contact has decades of sender reputation built up, and their compliance team actively monitors accounts for spam-like behavior. This long track record means most email providers trust Constant Contact's infrastructure by default.

Brevo offers more technical deliverability tools — dedicated IP addresses, detailed sending statistics, and the ability to separate your transactional and marketing sending reputations. For businesses with technical teams who want granular control over their email deliverability, Brevo provides more levers to pull. You can also validate your sending setup using tools like our email validator.

API and Developer Experience

If your team includes developers who need to integrate email into your product, Brevo has a significant advantage. Its REST API covers marketing campaigns, transactional email, SMS, contacts management, and automation — all from a well-documented, modern interface. Constant Contact has an API too, but it is more limited in scope and less frequently updated.

For SaaS companies building product-led email workflows, neither API is ideal. Both lack native support for subscription billing events and SaaS lifecycle triggers. Sequenzy's API is designed specifically for this use case, letting you trigger transactional emails based on Stripe events without building custom middleware.

The Email-Based vs Contact-Based Pricing Revolution

The pricing model difference between these platforms is more important than the sticker prices suggest. Brevo charges based on email volume, not contact count. Constant Contact charges based on contacts, regardless of how often you email them. For businesses with large lists that send infrequently, such as monthly newsletters to 50,000 contacts, Brevo's model can cost 80% less because you only pay for the emails you actually send.

Conversely, for businesses with small lists that email multiple times daily, such as transactional-heavy e-commerce, Brevo's per-email model can scale up quickly. The right pricing model depends on your sending ratio: if you email each contact less than 4 times per month, Brevo is almost always cheaper. If you send daily to your entire list, run the math carefully before assuming Brevo's headline price reflects your real cost.

The CRM Nobody Asked For But Brevo Included Anyway

Brevo bundles a CRM at no extra charge, which sounds impressive until you evaluate it against dedicated CRM tools. The CRM handles basic contact management, deal tracking, and pipeline visualization. For small businesses currently tracking customers in spreadsheets, it is a genuine upgrade. For businesses already using HubSpot, Salesforce, or even Pipedrive, Brevo's CRM is too basic to replace them.

The real value of Brevo's CRM is data unification. When your email marketing, SMS campaigns, WhatsApp messages, and CRM conversations all live in one platform, you get a unified view of each contact's history across channels. Constant Contact has no CRM at all, meaning contact insights are limited to email engagement data. For small businesses that want one tool to handle customer communication and basic sales tracking, Brevo's bundled CRM eliminates the need for a separate subscription and the integration headaches that come with it.

Why Event-Heavy Organizations Should Ignore the Price Difference

For nonprofits, community centers, and event-focused businesses, Constant Contact's event marketing features justify the price premium despite Brevo's dramatic cost advantage. Building event registration pages, tracking RSVPs, sending automated reminders, and managing attendee lists from the same platform as your email campaigns eliminates the need for Eventbrite ($50-200/month) or similar tools. The effective cost comparison becomes $80/month for Constant Contact versus $25/month for Brevo plus $50-100/month for a separate event platform.

If your organization runs three or more events per quarter, the integrated workflow saves both money and the hours of manual data syncing between separate platforms. SaaS companies running webinars might consider this angle too, but for subscription software businesses the more impactful integration is billing data, not event data. Sequenzy's Stripe integration addresses that specific need by connecting subscription lifecycle events directly to email automation at $49/month.
