About IMAP

Why IMAP matters

IMAP reads your mailbox — it's how outreach tools detect replies and manage your unified inbox.

Without a working IMAP connection, replies won't sync and sequences won't auto-pause.

IMAP almost always uses port 993 with SSL/TLS. App passwords are required when 2FA is on.

Still curious? Our team responds in under an hour.

It connects to your IMAP host (usually port 993 over SSL) and authenticates, confirming the mailbox can be read for reply tracking.

Outreach platforms use IMAP to detect replies, sync your inbox and automatically stop sequences when a prospect responds.

Port 993 with SSL/TLS is standard for secure IMAP. Some providers also offer 143 with STARTTLS.

Wrong host/port, an incorrect password (use an app password with 2FA), or the provider disabling external IMAP access.
