At a glance
What each Mailjet alternative is best for
- Resend
4.8 / 5
- Resend is a developer-first email API for React and Next.js teams. The catch is no HIPAA BAA, US-only data storage, and reports of abrupt account suspensions.
- OneSignal Email
4.7 / 5
- OneSignal Email offers a generous free tier within its multichannel push platform. The catch is email is secondary to its core push product and less mature than specialists.
- Postmark
4.6 / 5
- Postmark is a transactional email service with strong deliverability and streams that isolate message types. The catch is no marketing focus, no HIPAA BAA, and US-only data storage.
- Brevo
4.5 / 5
- Brevo is a GDPR-first, EU-based platform bundling email, SMS, WhatsApp, and CRM. The catch is it is not a purpose-built transactional provider, with strict anti-abuse suspensions.
- Loops
4.5 / 5
- Loops bundles marketing, lifecycle, and transactional email for SaaS teams with automated deliverability setup. The catch is a young company with no SOC 2, HIPAA, or EU data residency.
- Customer.io
4.4 / 5
- Customer.io is a lifecycle messaging platform with deep behavioral segmentation and a visual workflow builder. The catch is a steep learning curve and profile-based pricing that climbs with your audience.
- AWS SES
4.3 / 5
- Amazon SES sends high-volume email through AWS at among the lowest costs at scale. The catch is a bare-bones service with no template editor, campaign UI, or analytics.
- Mailgun
4.2 / 5
- Mailgun is a developer email API with strong deliverability and validation tooling and an EU region. The catch is inconsistent deliverability and support quality across reviews.
- Mandrill
4.2 / 5
- Mandrill is a transactional email add-on tightly integrated with the Mailchimp ecosystem. The catch is it requires a paid Mailchimp plan and will not sign a BAA.
- MailerSend
4.1 / 5
- MailerSend is a developer-focused transactional email and SMS API from the MailerLite team, with EU-hosted data by default, a real free tier, and built-in email verification. The catch is no formal SOC 2 Type II or HIPAA, and reports of accounts suspended over bounce-rate triggers.
- SendGrid
4.0 / 5
- SendGrid is a high-volume email API with dedicated IPs, deliverability tooling, and detailed analytics. The catch is support: slow responses and occasional account suspensions, reflected in a low Trustpilot score.
- SparkPost
4.0 / 5
- SparkPost (now Bird) is a high-volume email API with strong deliverability and analytics. The catch is no HIPAA BAA and poor reviews since the 2023 Bird rebrand.
FAQ
Common questions
The strongest Mailjet alternatives depend on what you need. Resend rates highest among the options here; the comparison table covers price, free tier, and rating, and the "what each alternative is best for" section matches each option to a use case.

Mailjet handles both transactional and marketing email from a single account. It offers a REST API and SMTP relay for transactional sends such as receipts and password resets, plus a drag-and-drop editor, contact lists, and automation for marketing campaigns. It is now part of Sinch, which also owns Mailgun.
Mailjet lists itself as HIPAA ready and says it supports HIPAA-compliant configurations for healthcare and other regulated industries upon request. As part of Sinch, a signed Business Associate Agreement (BAA) is available as a contract addendum for eligible products. Organizations handling protected health information should confirm BAA terms directly with Sinch before sending regulated healthcare data.
Mailjet's paid plans start at USD 9 per month for the Starter tier, which includes 8,000 emails per month and removes the free plan's daily sending limit. Higher tiers such as Essential and Premium add automation, segmentation, and dedicated IP options, and custom enterprise pricing is available. Pricing scales primarily by email volume.
Yes. Mailjet stores customer data in data centers located within the European Union and is certified GDPR-compliant by AFNOR. It was also one of the first email service providers to achieve ISO 27001 certification, which makes it a common choice for European data-residency requirements.
Often, yes. Courier sits in front of these providers behind one API, so you can route through Mailjet or an alternative, or fail over between them, without rewriting your integration each time.
