MailerSend

Overview

MailerSend is a transactional email service designed specifically for sending automated, trigger-based emails rather than marketing newsletters. MailerSend is a cloud-based transactional email service designed for sending automated, trigger-based emails such as order confirmations, password resets, welcome messages, and shipping notifications . Created by the team behind MailerLite, MailerSend focuses on transactional email delivery , separating this specialized email type from bulk marketing campaigns.

MailerSend is a transactional email service, not an email marketing service, as ISPs treat different types of emails differently . For newsletter creators, this distinction matters because transactional emails serve different purposes and follow different regulations than promotional newsletters. Transactional emails include subscription confirmations, password resets, purchase receipts, account notifications, and similar automated messages that individual subscribers trigger through actions rather than mass campaigns sent to entire lists.

The platform emphasizes developer-friendly implementation while maintaining an intuitive interface that allows non-technical team members to contribute. For newsletter creators running membership sites, paid subscriptions, or digital product businesses, MailerSend handles the behind-the-scenes email infrastructure that supports the business operations while keeping marketing newsletters on separate platforms designed for that purpose.

Best For

MailerSend works best for newsletter creators who also run membership sites, online courses, or digital product businesses that require reliable transactional email infrastructure. This includes creators selling paid newsletter subscriptions who need to send payment confirmations and renewal notices, course creators delivering automated lesson emails, membership site operators sending login credentials and account updates, and entrepreneurs with digital storefronts requiring order confirmations. The service suits technically comfortable creators or those with development resources, as implementation typically involves API integration or SMTP configuration.

Key Features

• Reliable Transactional Delivery: MailerSend specializes in the high-priority, time-sensitive emails that support business operations rather than promotional content. The infrastructure ensures critical messages like password resets or payment confirmations reach recipients quickly and reliably. For newsletter creators running subscription businesses, this reliability matters significantly more than for optional promotional emails.

• Team Collaboration: The platform supports up to 5 users on the free Hobby plan , allowing technical and non-technical team members to access the system. This collaborative approach means developers can handle integration while content creators or customer support staff can manage email templates and monitor delivery without requiring technical knowledge for every task.

• Developer-Friendly APIs: MailerSend provides comprehensive APIs and SMTP relay options that integrate with existing applications and platforms. Newsletter creators building custom membership platforms or integrating with tools like WordPress, Shopify, or custom applications can implement transactional email sending programmatically. The developer focus makes MailerSend suitable for technical implementations beyond basic email sending.

• Email Template Editor: The platform includes a visual email template editor for designing transactional email layouts, making it straightforward to create branded confirmation emails, welcome messages, and notifications without writing HTML. For newsletter creators who want transactional emails matching their brand identity, this template system maintains consistency across all customer communications.

• Analytics and Tracking: MailerSend provides delivery tracking, open rates, and click tracking for transactional emails, giving visibility into whether critical messages reach recipients. This monitoring capability helps identify delivery issues quickly, which matters significantly for transactional emails where delayed delivery can impact customer experience or business operations.

Pricing

MailerSend offers a free Hobby plan allowing up to 3,000 emails per month , suitable for small operations with limited transactional email needs. Paid plans range from $28 to $88 monthly with annual billing, structured around sending volume rather than contact counts . Emails sent beyond plan allowances cost $0.80 per 1,000 additional emails , providing flexibility for variable sending volumes without requiring plan upgrades for temporary spikes. Both Hobby and Starter plans include up to 5 users, while Professional and Enterprise plans offer unlimited user seats . The volume-based pricing makes MailerSend cost-effective for creators with predictable transactional email needs, though creators must remember this service complements rather than replaces dedicated newsletter platforms.
