deliverability
In short and in plain language
Deliverability tells you if a sender's emails get to the inbox.
If not, they end up in the spam folder. Or they do not arrive at all.
Records for the domain can play a part. So can the sender's good name and well-kept lists.
This is true for newsletters, but also for bills and replies to questions.
Definition
Deliverability describes whether the emails of a sender actually reach the inbox rather than the spam folder or not arriving at all. Technical records for the domain, the reputation of the sender and well-kept recipient lists can influence it. This affects newsletters as well as invoices and replies to enquiries.
