⟩ What is the mean of "Email deliver-ability and email open rates"?
These are two important email marketing metrics that should serve as the initial measure of your email marketing success.
Email deliverability rate (or acceptance rate) is the success rate of getting an email delivered to a person's email address. To find out the deliverability rate of your email marketing, you simply take the number of emails delivered and divide it by the number that were sent.
