What is MailerSend?
MailerSend is a transactional messaging platform that reliably delivers the emails, SMS and WhatsApp messages your app sends — order confirmations, password resets, shipping updates and more — at scale, via a simple API or SMTP. Built with developers in mind but usable by whole teams, it focuses on deliverability so the messages your users actually need reach their inbox.
What is MailerSend?
MailerSend handles the sending side of application messaging across three channels — email, SMS and WhatsApp — from one dashboard. You integrate via API or SMTP, design messages with a drag-and-drop template builder, and get real-time activity tracking, webhooks and logs so you can see exactly what's delivered, deferred or bounced. It's engineered for reliable, high-volume transactional delivery.
Who it's for
MailerSend serves SaaS companies and developers, e-commerce businesses that send order and shipping notifications, agencies managing multiple clients, and startups that just need messages to arrive. Anyone whose product depends on transactional messaging — and can't afford it landing in spam — is the target user.
Key features
- Transactional email via API or SMTP
- SMS sending and receiving with toll-free numbers
- WhatsApp Business API integration
- Drag-and-drop template builder with an HTML editor
- Real-time activity tracking, webhooks and API/SMTP logs
- Automatic bounce and suppression management
- Email verification (bulk or real-time via API)
- RBAC, SSO and 2FA for team access control
Deliverability first
MailerSend's whole reason for being is getting messages delivered. It manages bounces and suppression lists automatically, offers email verification to clean your lists, and provides real-time activity data and logs so you can diagnose deliverability problems fast. With a 99.5% uptime guarantee behind it, that focus means the transactional messages your users are waiting on — a reset link, a receipt — actually show up.
More than email
Unlike email-only competitors, MailerSend unifies email, SMS and WhatsApp in a single platform and dashboard. That lets you reach users on the channel that fits the message — an SMS for a delivery alert, WhatsApp for a conversational update, email for a detailed receipt — without integrating three separate providers. For a growing product, consolidating multi-channel messaging in one place is a real simplification.
Fast for developers
MailerSend is built to get you sending quickly. Multi-language SDKs — Node.js, PHP, Laravel, Python, Ruby, Go and Java — plus clean API and SMTP support mean integration is straightforward, and testimonials cite going live within 24 hours and sending at scale within a week. The drag-and-drop template builder lets non-developers design messages too, so engineering isn't a bottleneck for every email tweak.
Secure and compliant
MailerSend takes security and compliance seriously: it's GDPR-compliant with EU data centers and ISO 27001 certified, and offers RBAC, SSO and 2FA to control team access. For businesses handling customer data across regions, those credentials — plus 24/7 multilingual support — make it a dependable choice rather than a risky one.
Priced to scale with you
MailerSend's pricing grows with usage rather than punishing early-stage projects: a free tier covers 500 emails a month, with paid plans from $7/month (5,000 emails) up through higher tiers that add SMS, plus pay-as-you-go overage rates and add-ons for verification and WhatsApp. That predictable, usage-based model suits everyone from a side project to a high-volume SaaS.
Why choose MailerSend
For any product that depends on transactional messages reaching users, MailerSend is a reliable, developer-friendly choice. Its deliverability focus, multi-channel email/SMS/WhatsApp support, strong SDKs, security credentials and scalable pricing make it a practical way to send the messages your app can't afford to lose — without stitching together separate services to do it.
