🚀 How to Use Amazon WorkMail for Bulk Email Sending with Multiple Domains

Email marketing is a game-changer for businesses. But finding a reliable SMTP server for bulk email sending can be a challenge. Luckily, Amazon WorkMail SMTP can be exploited to send mass emails daily without getting blacklisted. This guide will walk you through how to send bulk emails using multiple domains via Amazon WorkMail SMTP and boost your email marketing efforts.

✅ Why Use Amazon WorkMail for Bulk Emails?

Amazon WorkMail is a secure email service, but its SMTP settings can be used to send bulk emails. Unlike Amazon SES, which has strict sending limits and verification requirements, WorkMail offers a way to bypass some restrictions while maintaining good email deliverability.

Generate DKIM keys in AWS WorkMail
Configure DMARC policy in DNS

✅ Use a Custom Tracking Domain

Avoid sending links using generic URLs. Instead, set up a custom tracking domain for better email reputation.
