eimmigration's integrations page says that once the firm's Outlook account is connected, client email sent through it is logged with its attachments on the matching case or client profile, and nobody has to file it. The same page lists a Microsoft Exchange connection for sending email and logging it on client and case records, and a Gmail connection for a firm whose mail runs on Google.
The client management page describes a communications center where staff send, receive, and answer emails from a client profile or from a system inbox. So a paralegal can write to the client from the client's record.
On eimmigration's pricing page, Email Server Integrations is one of the 48 standard features in every plan. Mail! Anywhere is a premium feature, described as searching an email inbox and logging messages directly to client and case profiles. Starter includes one premium feature of the firm's choice, Essentials includes four, and Complete includes all of them.
Suppose a paralegal has exchanged 12 emails with an H-1B beneficiary from the client profile, and the employer's HR manager then sends the signed support letter straight to the attorney's Outlook inbox. The 12 emails went through the connected account, which is the situation the Outlook listing describes. The HR manager's email came from a third party and started outside the client record. Ask eimmigration to show how that message and its attachment reach the H-1B case, and whether the firm would need Mail! Anywhere for it.
In Docketwise, the attorney would open that email in Outlook and check the suggested contact, since the sender is the HR manager and the matter belongs to the beneficiary.
