Email Digit is an email-sending platform for marketers and developers, built around deliverability and the replies that follow. It manages SPF, DKIM and DMARC authentication for sending domains, helps users check and improve DNS configuration, and provides tools for monitoring DMARC reports and spam scores. The service also supports signing-key rotation and gradual sending limits to help protect a domain’s reputation.

For marketers, Email Digit offers broadcasts, automations, audience segments and an editor that can use AI to draft campaigns in a brand’s voice and style. Pre-send checks cover items such as spam scores, links, authentication, suppression lists, frequency and budget. Reporting emphasizes replies and revenue, while incoming messages are categorized and prioritized, with suggested drafts for important responses.

For developers, the platform provides transactional email through an authenticated API, test keys, searchable send records and email journeys generated from a description. Free tools, documentation, guides and API references are also available.
