Email deliverability refers to the ability of an organisation's marketing emails to successfully reach the intended recipients' inboxes, without being marked as spam or encountering other delivery issues. It encompasses a set of strategies and technical practices aimed at ensuring that emails are authenticated, trusted by email service providers, and adhere to industry standards and regulations. Effective marketing email deliverability involves maintaining a clean and updated email list, implementing authentication protocols like SPF, DKIM, and DMARC, segmenting and personalising email campaigns, monitoring performance metrics, and adhering to best practices to optimise engagement and conversion rates. By prioritising deliverability, organisations can enhance their email marketing effectiveness, establish positive sender reputations, and foster stronger connections with their audience.
