You may try importing SMTP list instead of typing them one by one. One ATelMailer can export their entire SMTP list, so, another user can import the same list and saves time.

• From the main interface, click on SMTP Servers button
• Now at the left side, click on Import SMTP List button
• We support both CSV and Microsoft Excel format to export files
• Just select folder file name to export
• Click on Export button.
