About MailerSend
MailerSend
EmailMailerSend is a developer-focused transactional email and SMS API built by the MailerLite team and now part of Vercom, offering a developer API, SMTP relay, drag-and-drop templates, and EU-hosted data by default. The catch is no formal SOC 2 Type II certification or HIPAA BAA, dedicated IPs gated to higher tiers, and Trustpilot reports of accounts suspended over bounce-rate triggers.

At a glance
What each MailerSend 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.
- 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 MailerSend 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.
MailerSend is built specifically for transactional email and SMS, things like password resets, order confirmations, and account notifications sent by an application. It is a sister product to the marketing platform MailerLite, and both are now owned by Vercom S.A., but MailerSend's own API, dashboard, and pricing are scoped to transactional and developer-triggered sending rather than marketing campaigns.
No. MailerSend's public security statement and legal pages describe GDPR compliance, a Data Processing Addendum, and PCI-DSS compliant payment processing, but do not mention HIPAA or a Business Associate Agreement. Teams handling protected health information should look elsewhere or confirm directly with MailerSend's sales team before sending PHI.
MailerSend's paid Hobby plan starts at 7 USD per month (6.30 USD per month billed annually) for 5,000 emails, with overage billed at 1.50 USD per additional 1,000 emails. The Starter plan is 35 USD per month for 50,000 emails, and Professional is 110 USD per month, covering the same base volume but adding unlimited seats and domains, longer log retention, a dedicated account manager, and deliverability consultation. Enterprise pricing is custom.
Yes. MailerSend hosts its infrastructure in Belgium through Google Cloud EMEA Ltd, and that data center holds ISO 27001 certification. This gives MailerSend EU data residency by default, which is notable since several developer-focused email competitors only offer EU sending regions while still storing account data in the United States.
Often, yes. Courier sits in front of these providers behind one API, so you can route through MailerSend or an alternative, or fail over between them, without rewriting your integration each time.
