Deliverability

In the context of email communications, deliverability pertains to an ESP's capacity to successfully deliver emails to the inboxes of subscribers. Upholding strong email deliverability is a critical factor in nurturing a positive sender reputation, which, in turn, contributes to higher chances of emails reaching the intended recipients' inboxes.

Warm up, domain reputation, IP reputation, subscriber engagement, inbox placement, content, links, images, and varying policies of different ISPs are among the independent factors that determine where an email lands in the inbox.
