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
