Overview

Brevo (formerly Sendinblue) and SendGrid approach email from different angles. SendGrid built its reputation on transactional email for developers. Brevo grew as an all-in-one marketing platform with transactional capabilities added later. See our Brevo comparison and SendGrid comparison for more details.

The right choice depends on whether you prioritize developer tools or marketing features.

The Core Difference

SendGrid is a developer-first email API. It powers transactional email for companies like Uber, Spotify, and Airbnb. The API documentation, webhooks, and delivery infrastructure are excellent.

Brevo is a marketing-first platform. It bundles email campaigns, SMS, WhatsApp, live chat, and CRM. Transactional email is included but not the primary focus.

Pricing Comparison

Brevo charges per email sent with unlimited contacts. At 20,000 emails/month, you pay $25 on the Starter plan. This works well for large lists with moderate email frequency.

SendGrid has separate pricing for Email API and Marketing Campaigns. You might need two subscriptions if you want both transactional and marketing capabilities. Marketing Advanced starts at $60/month for 10k contacts.

Transactional Email

SendGrid wins for transactional email. The API is more comprehensive, webhooks are more detailed, and the developer experience is polished. Built-in email validation and dedicated IPs make high-volume sending easier.

Brevo handles transactional email but with a simpler API. It works for most use cases but power users may find it limiting.

Marketing Capabilities

Brevo wins for marketing. The visual email builder, automation workflows, and segmentation are more developed than SendGrid's marketing tools.

Brevo also includes SMS and WhatsApp natively, plus live chat. SendGrid relies on Twilio integration for SMS.

When Each Platform Shines

Choose SendGrid when: You prioritize transactional email. Your team has developer resources. You need enterprise-grade deliverability. You're already in the Twilio ecosystem.

Choose Brevo when: You want all-in-one marketing. You need SMS and chat alongside email. You prefer per-email pricing. Your marketing team needs independence from engineering.

For SaaS Companies

Both platforms serve SaaS companies but neither is built specifically for software businesses. SendGrid handles transactional email well. Brevo adds marketing capabilities.

Neither understands subscriptions or billing. For Stripe integration and SaaS-specific automation, consider Sequenzy.

The Dual Subscription Problem

SendGrid's most criticized quirk is its pricing architecture. Email API and Marketing Campaigns are billed as separate products with separate plans. A company that needs both transactional receipts and marketing newsletters pays two subscriptions. At moderate volume, the combined cost can exceed what competitors charge for unified access.

Brevo sidesteps this entirely by bundling everything into a single bill. Transactional email, marketing campaigns, SMS, and CRM all fall under one plan. For teams that need both transactional and marketing email, the pricing simplicity is a genuine advantage. No mental overhead calculating whether your use case fits the API plan, the marketing plan, or both.

The dual subscription also creates friction during growth. As your transactional volume increases, you upgrade the API plan. As your contact list grows, you upgrade the marketing plan. These upgrades happen independently with different pricing curves, making cost forecasting harder than it should be. Brevo's single per-email pricing model, while imperfect, is at least predictable.

Deliverability Infrastructure Differences

SendGrid has spent over a decade building email deliverability infrastructure. Dedicated IP addresses come included on Pro plans. IP warmup guides, suppression management, and sender authentication tools are deeply integrated. For companies sending millions of transactional emails, this infrastructure maturity matters - every fraction of a percentage point in delivery rate translates to real business impact.

Brevo's deliverability is good but not at the same infrastructure depth. Dedicated IPs are available as paid add-ons rather than included features. The platform handles domain authentication and basic deliverability monitoring well, but high-volume senders report more variability in delivery rates on shared IP pools compared to SendGrid's managed reputation system.

The practical gap narrows for most businesses. Both platforms deliver marketing emails effectively when you follow authentication best practices and maintain clean lists. The deliverability difference is most pronounced at high transactional volumes where SendGrid's infrastructure maturity provides measurable advantages in inbox placement rates.

The Twilio Ecosystem Factor

SendGrid's acquisition by Twilio in 2019 created an interesting ecosystem dynamic. Companies already using Twilio for voice, SMS, or video gain seamless integration with SendGrid for email. The shared authentication system, unified billing, and cross-product APIs reduce the friction of building multi-channel communication stacks.

However, this ecosystem lock-in cuts both ways. SendGrid's SMS capability requires Twilio, not a native feature. If you want SMS marketing alongside email, you are committing to the Twilio pricing model for messaging. Brevo's native SMS is simpler and often cheaper for basic marketing use cases, though Twilio's SMS is more powerful for programmatic messaging.

For SaaS companies evaluating both platforms, the ecosystem question matters less than it appears. Most B2B SaaS products need email as the primary channel with transactional notifications for events like password resets, billing receipts, and usage alerts. Sequenzy handles this unified email need with native Stripe integration, purpose-built for subscription businesses rather than general communication infrastructure.
