Overview

Cloudflare Email Service and Mailjet target different parts of the email landscape. Cloudflare is a thin transactional pipe with Workers integration. Mailjet is a mid-tier marketing + transactional platform with a unique real-time collaboration feature for template editing.

The Collaboration Feature

Mailjet's signature feature is real-time collaborative template editing - multiple team members editing the same email simultaneously, like Google Docs for email. For marketing teams that work together on campaigns, this is genuinely useful. Cloudflare Email has no editor at all.

Marketing Features

Mailjet includes drag-and-drop templates, marketing campaigns, basic automation workflows, and A/B testing. Cloudflare Email has none of this. If you need marketing, Mailjet wins.

Workers Integration

Cloudflare's send_email binding is unique inside Workers. Mailjet works fine via REST and SMTP but doesn't have a binding.

SMTP Support

Mailjet supports SMTP relay. Useful for legacy apps or apps with existing SMTP integrations. Cloudflare Email is API-only.

Pricing

Roughly tied at 100k emails/mo. Cloudflare ~$39 vs Mailjet Essential $35. Mailjet's slight price advantage includes the marketing platform.

Sinch Acquisition

Mailjet was acquired by Sinch (the same parent as Mailgun) and some users report post-acquisition support quality and pricing concerns. Cloudflare is well-resourced and stable.

When Each Wins

Cloudflare Email wins for Workers-native apps, pure transactional needs, AI agent use cases, and teams that prefer Cloudflare over Sinch.

Mailjet wins for marketing teams that collaborate on templates, apps that need SMTP relay, and teams that need both marketing and transactional.

The Marketing Alternative

For SaaS-specific marketing with Stripe integration and AI sequence generation, Sequenzy is purpose-built and unifies transactional + marketing.
