Bulk email software is software that is used to send emails in large quantities. Bulk email software usually refers to standalone software, while there are bulk email sending web-based services as well.
Bulk email is the act of sending one email campaign to a large group at once. Marketing messages, newsletters, updates, coupons, and invitations typically comprise bulk emails. Synonymous with mass email or email blasts, bulk emails focus on sending one central message to a large group of subscribers.
A bulk email service is a company that allows its customers to send mass email messages to multiple lists of recipients at a specified time. With this service, you can send a single message to thousands of people on a mailing list or a personalized email to each address on a list.
