Segregate with Sub-Accounts

You can have unlimited sub-accounts in SendPost. Use them to have separate email sending IPPools, analytics and sending domain. If you are sending promotional and transactional emails, sending emails from multiple domains (big volume sender) or sending emails for multiple customers (ESP) then sub-account management will be your life-saver.

Group for Analysis

Understanding which emails are working or not working is hard. Diagnosing which campaign performed better or worse and why is harder. Groups provide you a flexible way to categorize your emails using API for later analysis and email deliverability diagnosis.

No limits

You do not have to worry about running out of sub-accounts or groups. We don not have any artifical limits. You can have as many sub-accounts and groups as you like. No restrictions whatsoever.
