Can we select just one or multiple server (or domain) to send from at a time?

When you have multiple mailing servers, you can choose which servers to use when sending your email campaigns. You have the flexibility to select one or multiple servers for sending emails.

Each server is associated with a specific domain. So, if you choose a particular server, emails will be delivered via that specific domain.

For example, in an advanced server setup, you might have three servers available for sending emails. During the setup stage of sending email campaigns, clicking on the "Show More" button will reveal the option to select the mailing servers.
