Definition
💡 Mass email sending—also known as bulk email sending, email blast, or mass mailing—is the process of sending a large number of emails to multiple recipients at once. This is often done for marketing purposes, such as promoting products or services to a wide audience.
Note that mass email sending should always comply with anti-spam regulations and guidelines.
Example
Online retailer Honeybuzz 321 sends mass emails to launch a new product line to its customer base. The emails are sent to thousands of subscribers and offer a special discount or promotion for the new products.
Sending a mass email without showing addresses
One common concern with mass email sending is privacy and the visibility of recipient addresses. Fortunately, there are ways to send a mass email without showing recipients all the email addresses.
- Use the BCC (Blind Carbon Copy) option. This allows you to email multiple recipients without them seeing each other's email addresses.
- Use a mailing list or newsletter service. These platforms send emails one-on-one, and subscribers see only one recipient in the email—themselves.

When to use a tool for mass email sending
Using a tool for an email blast would be beneficial for the following:
- Marketing campaigns: When promoting a new product or service, sending a mass email to targeted recipients can help spread the word in one go.
- Newsletter updates: If you have regular updates or news to share with your audience, an email blast tool can save you time and effort in sending the same message to hundreds or thousands of people.
- Event invitations: For businesses that host regular events or webinars, sending out mass emails to invite potential attendees can increase registration and ensure timely delivery.
