What is High Volume Email Sending?

High volume email sending is also known as mass email sending.

It refers to marketers that require large send capabilities, which can be in excess of 200,000 subscribers.

It's good to note that sending the same message to everyone is discouraged, since segmentation will offer far more effective results. Also, email senders need to avoid being associated with spam, which can also happen if sending mass campaigns often.

By following best practices, high volume senders can reach the maximum number of users in a way which will deliver campaign success.

Example

A large e-commerce company with 500,000 subscribers sends out a weekly newsletter promoting different product categories. Instead of sending the same email to everyone, they segment their audience and send personalised versions: fashion items to clothing shoppers, electronics deals to tech enthusiasts, and home goods promotions to interior design followers. This targeted approach to high-volume sending results in better engagement rates and fewer unsubscribes than a one-size-fits-all campaign.
