Configuring Mailers

Configure Mailers lets you connect Master SMTP to the email service you want to send through (SMTP or API), then choose which connection each email should use. In this section, you’ll add and verify a mailer, set the From name and email, and confirm delivery with a quick test. Once configured, Master SMTP can route emails through the best sender automatically, log results, and help you avoid common delivery issues like spam flags and failed sends.
