Why is it important to have multiple mailboxes?

Having multiple mailboxes is crucial for any business. Utilizing a variety of mailboxes enhances email deliverability and helps in maintaining a positive reputation.

  • 01 Enhanced Email Deliverability:

    Multiple mailboxes help distribute the sending load, reducing the chances of your emails being marked as spam. This ensures a higher success rate in your email delivery to your target audience.

  • Using different mailboxes for various types of communication (like marketing, newsletters, customer support) helps in managing your sender's reputation. It separates different types of email traffic, which can be crucial for maintaining a good sender score.
