### [Maileroo](https://www.g2.com/products/maileroo/reviews)

Maileroo is a transactional email platform built for developers, founders, and engineering teams who need password resets, receipts, notifications, and other system-generated emails to land reliably, without paying enterprise prices for it. 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.

Email deliverability tools help businesses monitor and optimize email campaigns to improve their inbox placement and reputation among recipients. These tools are advantageous within marketing and sales strategies, increasing open rates and conversion opportunities by ensuring emails bypass spam folders and are strategically composed to be perceived as legitimate. Email deliverability tools are used primarily by email marketers or organizational teams involved with sending bulk emails to contact lists and leads. Successful use of these tools can put valuable content or sales opportunities in front of more subscribers and help prevent emails from getting lost in the shuffle or tagged as spam.

Email deliverability software often integrates with [email marketing software](https://www.g2.com/categories/email-marketing), and a number of products in the Email Marketing category include features related to email delivery and inbox placement. These tools may similarly function in tandem with [marketing automation software](https://www.g2.com/categories/marketing-automation). Email deliverability software may offer features related to DMARC software to help ensure emails and email accounts are authenticated to avoid imposter activity that could cause flagging and poor inbox placement. Email deliverability platforms may also integrate with or offer features of [email tracking software](https://www.g2.com/categories/email-tracking) to monitor email performance, such as open rates, processing time, and email delivery latency.

To qualify for inclusion in the Email Deliverability category, a product must:

- Provide tools for testing and optimizing emails against up-to-date spam filter analyses
- Analyze sender accounts for potential flagging or placement issues
- Provide timely metrics related to email delivery and sender reputation
