The ability of an email to successfully reach a recipient's inbox rather than being diverted to their spam or junk folder. Deliverability is a critical factor for ensuring that marketing messages, promotions, or outreach efforts are effectively received by the intended audience. It is influenced by several factors, including the sender's reputation, the quality and relevance of the email content, and the proper configuration of email authentication protocols like SPF and DKIM. Additionally, maintaining a clean and engaged email list helps improve deliverability by reducing bounce rates and avoiding spam traps. Managing these elements effectively ensures that emails are delivered as intended, enhancing the success of marketing campaigns.
