Why MailerooBuilt for High-Volume Senders
Send through SMTP or API, track every message, and manage deliverability from one dashboard. No infrastructure to maintain, no mail servers to run.
Send emails your way
Copy your SMTP credentials, paste them into your app, and start sending. That's it. No complex setup, no mail server configuration, no infrastructure to manage. Prefer API? Drop in a few lines of code and you're done.
Real-time delivery reports and webhooks
View delivery activity from one dashboard, including delivered emails, opens, clicks, bounces, and suppressions. Spot failed sends, trace delivery issues, and understand exactly what happens after every message leaves your system. Set up webhooks to receive real-time event data in your own application, so your team can trigger workflows, send alerts, and keep everything in sync without checking the dashboard manually.
Simple & straightforward DNS setup
Maileroo gives you the SPF and DKIM records your domain needs, with simple setup steps and checks to catch common issues before they affect delivery. Using Cloudflare? One-click setup adds your DNS records automatically. And if something's off, our first-class DNS troubleshooter spots the problem and shows you exactly how to fix it. No DNS dramas. Just a cleaner path to sending.
