Overview

Mailjet and SparkPost (now part of Bird) serve different segments of the email market. Mailjet (owned by Sinch) offers budget-friendly unified email for SMBs. SparkPost is enterprise-grade infrastructure processing over 40% of global commercial email. See our SparkPost alternatives for more options.

SMB vs Enterprise

The fundamental difference is target market. Mailjet serves SMBs with transparent pricing and marketing features. SparkPost serves enterprises sending billions of emails who need proven infrastructure and sophisticated deliverability. If you are wondering which tier you fit, you are probably in Mailjet's market.

Deliverability Leadership

SparkPost processes more commercial email than almost anyone. Their deliverability technology includes predictive recipient validation, advanced analytics, and sophisticated IP warming. Mailjet has good deliverability, but SparkPost's scale and specialization put them in a different category.

Marketing Capabilities

Mailjet includes marketing campaigns, visual builder with real-time collaboration (Passport), automation workflows, and contact management. SparkPost focuses on transactional infrastructure with minimal marketing features. If you need marketing email alongside transactional, Mailjet is more complete.

Pricing Clarity

Mailjet offers transparent, predictable pricing starting at $15/month. SparkPost has usage-based pricing that can vary and enterprise tiers requiring custom contracts. For budget certainty and predictability, Mailjet is safer.

Company Backing

Both are backed by larger communications companies. Mailjet by Sinch. SparkPost by Bird (formerly MessageBird). Both have enterprise stability, though SparkPost's Bird integration is relatively recent (2021 acquisition).

The SaaS Alternative

Neither platform is built specifically for SaaS. Sequenzy offers unified marketing and transactional with native Stripe integration and behavioral automation, at transparent pricing simpler than SparkPost's enterprise model.

Making the Choice

Choose Mailjet for budget-friendly unified email with marketing and collaboration. Choose SparkPost for enterprise-grade infrastructure and industry-leading deliverability at scale. For SaaS with marketing automation and Stripe integration, consider Sequenzy.
