Strengths & Weaknesses
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
Resend
Exceptional developer experience with clean API syntax and React Email integration for building templates as code
Generous free tier (3,000 emails/month) and transparent pricing with no surprise charges or complex calculations
High deliverability rates maintained through pristine shared IP pools and automatic suppression list management
Fast implementation with official SDKs for all major languages and setup possible in minutes
Occasional delivery delays reported during peak hours, particularly for time-sensitive OTPs and transactional emails
Pricing becomes expensive at high volumes compared to alternatives like Amazon SES or Postmark
Some users report unexpected account suspensions without clear explanations or prior warnings
