UZonMail: Bulk Email Solutions
Send or schedule large emails to many people with UZonMail, a free and open-source bulk email platform.
"A founder wants to welcome new customers with a personalized email when they make a purchase from their online store. They use UZonMail to bulk-email the welcome message and set up an automation. Now their new customers get the email automatically, and they don't waste time sending them via their personal account."
