This add-on links the Newsletter plugin with the MailerSend transactional and marketing email service. It is designed for site owners who want to improve their email deliverability rates by using a dedicated sending infrastructure instead of their own web server.

• External Email Delivery: Routes all emails from the Newsletter plugin through MailerSend's servers, which can increase the likelihood of messages reaching the primary inbox.
• Domain Authentication Setup: Requires you to validate your sending domain (like mydomain.com) within MailerSend. This process involves updating DNS records, which helps prove your emails are legitimate to mailbox providers.
• API Token Connection: The integration is secured using a unique API token generated from your MailerSend account. You copy and paste this token into the add-on's settings to establish the link.
• Free Add-On: The extension itself has no cost. You only need a MailerSend account, which offers a free tier with limited sending volume.
• Centralized Management: After configuration, you can enable or disable the service from the plugin's settings and manage your sending domain directly from the MailerSend console.
