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.
FAQ
Common questions
The strongest Mandrill 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.
Yes. Several alternatives offer an ongoing free tier, including Resend. Check the "Free tier" column above; free allowances and limits vary by provider, and some offers are trials rather than perpetual free tiers.
Mandrill, now sold as Mailchimp Transactional Email, is a service for sending transactional (triggered) emails such as password resets, order confirmations, receipts, and shipping notifications. It delivers through both a REST API and SMTP relay. It is a paid add-on to Mailchimp and is separate from Mailchimp's marketing/bulk email product.
No. Mailchimp Transactional Email will not sign a Business Associate Agreement (BAA) and is not HIPAA compliant. It should not be used to send protected health information (PHI), and healthcare teams that need a BAA should choose a different provider.
Pricing is block based, where each block is 25,000 emails. Blocks cost $20 each for the first 20 blocks (up to 500,000 emails), then drop to $18, $16, $14, $12, and $10 per block at higher volumes. These charges are on top of a required Mailchimp Standard or Premium marketing plan, and dedicated IP addresses cost an additional $29.95 per month.
No. Mailchimp's servers are located in the United States, and it does not offer an EU data residency option. For EU personal data, Mailchimp relies on Standard Contractual Clauses in its Data Processing Addendum and the EU-US Data Privacy Framework rather than in-region storage. Mailchimp does maintain GDPR compliance, SOC 2 Type II reporting, and ISO 27001 certification.
Often, yes. Courier sits in front of these providers behind one API, so you can route through Mandrill or an alternative, or fail over between them, without rewriting your integration each time.
