Updated Jun 02, 2026
What is Lyne?
Lyne is an AI personalization tool for cold email. It creates tailored intro lines for each prospect in a click, so reps can keep the personal feel of one-to-one outreach while sending at volume.
It is strongest when scaling outbound campaigns quickly: users save several minutes per lead and can produce many personalized openers per hour, which suits agencies, consultants, and SDRs focused on cold outreach.
Lyne fits into CRM and email workflows as a personalization assistant rather than a full CRM or email-marketing platform. It is best paired with a sending tool to run the campaigns.
