Mailboxes
Connect the mailbox your customers write to and every customer email arrives in Replyco as a ticket, next to your marketplace messages and chats, and your replies go back by email. Each connected mailbox is one account in Replyco: it labels every ticket it brings in, and your team works the conversation there instead of in a shared inbox.
Replyco connects a mailbox in four ways. Gmail and Outlook sign in with Google or Microsoft and read and send through the provider itself, with no server settings. Any other mailbox connects through the Email tile, either by forwarding its mail to an address Replyco creates, or with IMAP and SMTP, where Replyco collects and sends mail through your own mail server. Every way starts from + Add Account in the top bar, in the group Mailbox Accounts. For marketplaces and webstores, see Marketplaces and Webstores.

Which way fits: a Gmail or Google Workspace address connects best as Gmail, and a Microsoft 365, Outlook.com or Hotmail mailbox as Outlook, because both keep working without passwords or server settings. A mailbox at any other provider connects with IMAP and SMTP when the provider offers them. Forwarding works with every mailbox, including a shared Microsoft 365 mailbox that has no sign-in of its own.

- Folders to sync. Gmail, Outlook and IMAP mailboxes can limit Replyco to chosen folders in Sync Messages from Folders:.
