MailerSend review
Affordable transactional email with API, SMTP, inbound routing, and webhooks.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
MailerSend is a transactional messaging service for developers and teams sending application-generated email. Its core tools cover a transactional email API, SMTP relay, inbound email routing and parsing, delivery-event webhooks, reusable templates, tracking, email verification, and multiple sender identities. That makes it a fit for account notifications, password resets, order updates, and other automated communications. Web, iOS, and API access support teams working across application and administrative environments.
Pricing is accessible for smaller workloads. The Free plan includes 500 emails per month, a 100-email daily limit, the Email API, SMTP relay, webhooks, and inbound routing. Hobby costs $7 per month and raises capacity to 5,000 emails, with 5 users, 10 templates, 5 webhooks, 1 inbound route, and 1,000 daily API requests. Starter costs $35 per month and adds 50,000 emails, 10 sending domains, 250 templates, 50 webhooks, 50 inbound routes, and 100,000 daily API requests. Professional costs $110 per month and keeps the 50,000-email allowance while expanding domains, templates, webhooks, inbound routes, and daily API requests.
MailerSend’s strongest functional angle is the combination of outbound and inbound email handling. Teams can send through the API or SMTP relay, respond to delivery events through webhooks, route incoming messages, and manage templates with drag-and-drop, HTML, or rich-text editors. Email tracking, activity logs, verification, and dedicated-IP support round out the delivery workflow. Small teams should pick MailerSend when they want broad transactional email capabilities without a large starting commitment. Organizations needing a higher-volume plan than the listed 50,000-email tiers or dedicated IP access without Enterprise eligibility should consider an alternative.
