HI!!

I would like to purchase Web-Mail service and check emails that arrived in my own service. I need the following features.

Please check if I need the features in this Smatter email. I couldn't find it no matter how many times I looked on the site, so I asked.
- APIs to search mailboxes by folder
- API for the number of emails not checked
- API for storing mail in external database

If I don't have the above API, how can I get support?
