Further email configuration
When a visitor to your website subscribes to your newsletter through a form (sumbits email address and agrees to receive emails from you), you can send emails to them. Tne newsletter subscription process must be configured first. There are two types of newsletter subscriptions: single opt-in and double opt-in.
The single opt in process saves the marketing agreement (email channel) without a user email confirmation. When a customer sends a newsletter submission form, the agreement is confirmed in their profile without requiring an email confirmation. The double opt-in process is also started when a customer submits the form, but the agreement is not saved to the customer’s profile until they click the confirmation link received by email.

It’s important to define the number of emails that are allowed to be sent in a particular time. Email limits does make sense because it prevents from overwhelming the recipients with multiple emails which are sent manually as an independent email campaign or sent automatically by automated scenario.
