DedupOutreach

Shows if a teammate already messaged this LinkedIn or X profile

Browser extensionfree

DedupOutreach is a free Chrome extension paired with a shared Google Sheet that shows instantly, on any LinkedIn, X, or other profile, whether a teammate has already reached out - so a small team never cold-messages the same person twice. It's built for small sales or growth teams doing outreach who don't want a full CRM just to avoid duplicate contact.
