A: Hello,

I want to clarify that we don't currently offer a sub-login account feature. However, you can create up to 10 different Brands within a single login credential and manage them all under one account. This should work well for your needs, especially if you have 2500 contacts.

If you have any further questions or if there's anything else I can assist you with, please don't hesitate to let me know.

Best regards,
Behlül
