Mailjet vs SendGrid

Budget-friendly all-in-one vs enterprise infrastructure

TL;DR

SendGrid (owned by Twilio) is enterprise-grade email infrastructure with separate transactional API and Marketing Campaigns products. Mailjet for budget simplicity, SendGrid for enterprise scale.

Key Differences

The main things that set these tools apart

Unified vs Split Products
Mailjet wins

Mailjet offers transactional and marketing in one product with one price. SendGrid splits these into separate products (Email API and Marketing Campaigns) with separate pricing. For teams needing both, Mailjet is simpler.

Enterprise Scale
SendGrid wins

SendGrid is owned by Twilio and handles billions of emails. It's the enterprise standard with 15+ years of reputation. Mailjet is solid but doesn't match SendGrid's scale credentials.

Budget Pricing
Mailjet wins

Mailjet is generally cheaper, especially for marketing + transactional combined. SendGrid's separate products mean you pay for each. For budget-conscious teams, Mailjet offers more value.

Developer Resources
SendGrid wins

SendGrid has more SDKs, better documentation, and larger community. More developers have used SendGrid, so more Stack Overflow answers exist. For developer resources, SendGrid wins.

SaaS-Focused Features

Native Stripe Integration

Trigger emails based on Stripe payments, subscriptions, and billing events. Neither Mailjet nor SendGrid offers native Stripe OAuth integration.

Simpler Than SendGrid Pricing

SendGrid's split products mean complex pricing. Mailjet is simpler but general-purpose. Sequenzy offers unified SaaS email with straightforward per-contact pricing.

Overview

Mailjet and SendGrid both handle transactional email and marketing campaigns but at different scales and philosophies. Mailjet offers a unified, budget-friendly platform since 2010. SendGrid (owned by Twilio) is enterprise-grade infrastructure with separate products for API and Marketing. Understanding this difference is key to choosing.

Unified vs Split Products

Mailjet's biggest advantage: one product for transactional and marketing with one price. SendGrid separates these into Email API (transactional) and Marketing Campaigns. If you need both, Mailjet is simpler and often cheaper. See our SendGrid alternatives for other unified options.

Enterprise Scale vs Budget Value

SendGrid handles billions of emails and is the enterprise standard. Twilio's backing means serious infrastructure. Mailjet is solid and handles high volume, but doesn't have SendGrid's enterprise credentials. For mission-critical, high-scale email, SendGrid has the reputation.

Developer Experience

Both have good APIs and documentation. SendGrid has more SDKs (7+ languages), larger community, and more Stack Overflow answers. Mailjet's API is simpler since it's one product. For developer resources and ecosystem, SendGrid wins.

Unique Mailjet Feature

Mailjet Passport allows real-time collaborative email editing - multiple people working on the same email simultaneously, like Google Docs. It's a unique feature SendGrid doesn't offer, valuable for teams with marketing/design collaboration needs.

The Unified Alternative

SaaS companies often find both Mailjet and SendGrid too general-purpose. Sequenzy offers unified marketing and transactional built specifically for SaaS, with native Stripe integration for payment-triggered emails - more focused than either option.

Making the Choice

Choose Mailjet for budget-friendly unified email with real-time collaboration. Choose SendGrid for enterprise-proven infrastructure and comprehensive developer tools. For SaaS needing marketing campaigns and transactional emails with Stripe integration, consider Sequenzy.
