MailerSend: The Complete Guide to Transactional Email for Developers and Marketers

In the modern digital ecosystem, email remains the backbone of customer communication. While marketing newsletters grab headlines, the unsung hero of the internet is transactional email—the password resets, order confirmations, shipping updates, and onboarding workflows that keep businesses running.

• No Marketing Automation: You cannot build drip campaigns or segment audiences. For that, you need MailerLite (their sister product).
• SMTP is not the focus: While SMTP works, the API is significantly faster and more reliable. If you are stuck with a legacy SMTP-only app, MailerSend works, but you lose template management.
• List Management: While you can import suppression lists, MailerSend is not designed to store millions of subscriber records. It is a sender, not a CRM.
