At a glance

What each Mandrill 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.
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.
Mailjet

4.0 / 5

Mailjet is a GDPR-certified email service with EU data storage and a drag-and-drop editor. The catch is a 200-per-day free cap and reports of inconsistent deliverability.
