Apollo handles cold email natively, with sequences and reply detection. Connecting Inboxlee mailboxes gives you the full Apollo workflow with Inboxlee infrastructure underneath.
Two connection paths
Apollo supports two ways to add a mailbox - direct OAuth with Google Workspace (or M365), and SMTP credentials. Both work for Inboxlee mailboxes. OAuth is simpler. SMTP is more flexible.
OAuth path
In Apollo → Settings → Email Accounts → Connect Account → Google Workspace. Sign in with the Inboxlee mailbox credentials (delivered via the secure one-time link). Apollo handles the OAuth handshake. Mailbox connected.
SMTP path
Apollo → Settings → Email Accounts → Connect Account → SMTP. Use the Inboxlee CSV export to get IMAP and SMTP credentials. Paste host, port, username, password into Apollo. Save.
CSV bulk import
Apollo supports CSV bulk import of email accounts. Inboxlee CSV format is compatible - for 10+ mailboxes, this is faster than connecting one at a time.
