Strengths & Weaknesses
Brevo
Contact-unlimited pricing model saves money as your list grows—you only pay for emails sent, not subscriber count
Genuinely useful free tier with 300 emails/day and 100,000 contacts, plus access to automation and CRM features
All-in-one platform includes email, SMS, WhatsApp, transactional email (SMTP/API), CRM, and live chat in one dashboard
Developer-friendly with robust API/SMTP support and SDK libraries for Node.js, PHP, Python, Ruby, Java, C#, and Go
Customer support can be slow on lower-tier plans, with some users reporting multi-day response times
Multi-user access is expensive—only included on Professional plan ($499/mo+) with 10 seats, then $28/additional user
Account validation process can be frustrating, with some legitimate users facing approval delays or rejections
Mailjet
Excellent API with comprehensive SDKs in 7+ languages and straightforward integration process
Strong deliverability focus with email validation, spam monitoring, and dedicated experts for high-volume senders
Built-in team collaboration features with permissions management and template locking to protect brand assets
Real-time analytics with bot filtering for accurate engagement metrics and detailed click maps
Daily sending limit of 200 emails on free tier may be restrictive for active development testing
No GraphQL API support for teams preferring modern query-based approaches
AI features (template generator, assistant) are newer additions and may lack maturity compared to core platform
