Yes, delivery and deliverability are linked, but they are not the same thing, you know?
While deliverability is about the metric, delivery is the process itself .
In short, delivery is the acceptance of the message. Whenever an email is sent to the recipient's provider and there is no return error message, it means that delivery has been made.
To do this, there are several steps:
message is sent by the sender;
the email is encrypted by the sender's azerbaijan phone number resource server, transferring the information to the internet;
the message delivery request is received by the recipient's server, which carries out a series of checks to ensure the sender is authentic;
The email, after approval, is delivered, and may be in the inbox or spam folder.
Every time a message passes through all these steps, we can consider that the email has been delivered. Messages that are blocked by the checks will not reach the recipient.
However, even though delivery may have occurred, this does not mean that the message reached the inbox. In other words, the marketing email you sent may have ended up in another location , such as the spam folder.
For this reason, delivery is the process of an email reaching the recipient, while deliverability is the rate at which messages sent reach the inbox.
