What is Bulk Email Service?
What is Bulk Email Means
A bulk email service allows you to send email communications to large lists of multiple recipients by incorporating email into your applications. You can send one email to many people, or a unique email to each person on your list with a bulk email service.
Why use Bulk Email Service
Commonly, bulk email is used for newsletters or marketing email. If you have a list of customers or prospects, you can send them to content relevant to their business or interest, from a single application. A bulk email service allows you to send to any list, regardless of its size. The frequency at which you send is entirely up to you and should be based on what the recipients expect. Your engagement data, including spam reports, unsubscribes, and open and click rates, will tell you whether your message is hitting the mark.
