You can send through SMTP (plug in your credentials and you're sending in minutes) or through a clean REST API with SDKs and copy-paste snippets in most major languages. Both support the things you actually use day-to-day: HTML and plain-text bodies, attachments, custom headers, custom tags for categorizing traffic, scheduled sending (RFC 3339 timestamps or natural language like "in 2 hours"), and per-message reference IDs so you can correlate sends with your own systems. On the delivery side, you get real-time webhooks for opens, clicks, bounces, complaints, and unsubscribes, plus a dashboard with detailed message logs, so when an email doesn't arrive, you can actually see what happened instead of staring at a vendor's silence. Dedicated IPs are available for higher-volume senders who want full control over their sending reputation, and a guided DNS wizard handles SPF, DKIM, and DMARC setup so authentication isn't a half-day project. Beyond sending, Maileroo includes an inbound parsing API to route incoming email straight into your application, a free email verification API to clean lists before they hurt your reputation, and a suite of free tools: SPF/DMARC generators, blacklist monitoring, a mail tester, that are useful whether you're a customer or not. Pricing is usage-based with a generous free tier. Connections are TLS-encrypted, accounts are protected with 2FA, and the platform is GDPR-compliant. ## Maileroo Pros & Cons **What users like:** - Users love the **easy setup** of Maileroo, enabling quick integration and a seamless experience for transactional emails.
