Bulk Email, also known as mass email or email blasts, is sending one email campaign (with one primary, central message) to a large group of recipients at the same time, simultaneously.
To achieve this you need a list of opted-in subscribers and an email marketing software that enables sending emails in bulk.
Personalization and automation make bulk emails more effective by delivering the right message to the right person at the right time.
You can still send bulk or mass emails out to all your audience, but with dynamic tools, for hyper-personalization, you can replace specific parts of the bulk email template with content that changes based on the recipient. This way, each recipient will see their own name, their own company, job title, or one-liner that speaks to their own business needs.
