Agents are used to segment the different email-sending channels. This helps you control and analyse each type of email you send. The manner in which you segment is up to your discretion. The common ways in which you can group the emails are:
Based on the emails sent out, like welcome emails, password reset emails, security codes like OTPs and more.
Based on the number of applications or businesses.
Based on the development environments.
Each Agent has its unique API and SMTP channel, ensuring a deeper separation. You can associate the desired domain with each Agent to carry out email sending.
