What is Email Deliverability?
Email deliverability refers to the capability of your emails to effectively land in users’ inboxes instead of being diverted to spam or completely blocked. The outcome hinges on factors such as the sender’s reputation, the effectiveness of authentication protocols, the quality of the content, the cleanliness of the mailing list, and the level of engagement from recipients.
A meticulously composed email holds no value if it fails to reach its intended recipient.
