Lyne.ai (lyne.ai) is an AI-powered cold email personalisation platform built to solve one of outbound sales' most time-consuming tasks: writing a unique, relevant opening line for every prospect. Instead of sending the same generic introduction to thousands of leads, Lyne.ai analyses publicly available data about each prospect — LinkedIn profiles, company news, recent activity — and generates a tailored first line that speaks directly to that individual. The result is higher open rates and reply rates without the hours of manual research. Lyne.ai operates on a pay-as-you-go credit model, with a free tier requiring no monthly subscription, making it accessible for sales teams of any size to test before committing.
The platform integrates with the outbound tools sales teams already use — including major cold email platforms and CRMs — and processes personalisation at scale, generating hundreds or thousands of tailored lines in the time it would take a human researcher to write a dozen. Each credit corresponds to one personalised row (one Lyne), and unused credits roll over on paid plans, preventing waste. The Custom plan at $120 per month provides access to 2,000 emails per month with unlimited Lynes and full integration access, at an effective rate of $0.25 per Lyne.
How Lyne.ai Works
Users upload a list of prospects — typically a CSV with LinkedIn URLs or company domains — and Lyne.ai's AI engine researches each person and company automatically, pulling from publicly available sources. Within minutes, the tool returns a personalised opening line for every prospect in the list. These lines are exported and inserted into cold email sequences in tools like Instantly, Smartlead, Lemlist, or any platform that supports custom variables. On the free plan, users pay only for credits used with no monthly charge; on the Custom plan, a monthly allocation of credits is provided with rollover and additional credits purchasable as needed.

Who Should Use Lyne.ai?
Lyne.ai is built for B2B sales teams, SDRs, and growth marketers running cold email outreach at scale. The free plan makes it an easy first step for individuals or small teams that want to experiment with AI personalisation before committing to a monthly subscription. The Custom plan suits outbound-heavy teams sending thousands of cold emails per month who need consistent personalisation without manual research overhead. Teams that send fewer than a few hundred emails per month may find the free pay-per-credit model more economical. Lyne.ai is a focused personalisation tool — teams also needing email sequencing, inbox management, or CRM capabilities will need to pair it with a dedicated outbound platform.
Frequently Asked Questions
What is Lyne.ai?
Lyne.ai is an AI cold email personalisation tool that automatically generates unique, research-backed opening lines for every prospect in a sales outreach list. It pulls from publicly available LinkedIn and company data to create personalised first lines at scale, improving open and reply rates for outbound email campaigns.
Is Lyne.ai free?
Yes. Lyne.ai offers a free plan with no monthly subscription. Users pay only per credit (per Lyne generated) on a pay-as-you-go basis, with no minimum spend. All integrations are included on the free plan, making it a genuine zero-cost entry point for testing AI personalisation.
What is a Lyne credit?
One Lyne credit equals one personalised row — meaning one AI-generated opening line for one prospect. On the free plan, credits are purchased as needed at $0.25 each. On the Custom plan, 2,000 credits are included per month and unused credits roll over to the following month.
Which cold email tools does Lyne.ai integrate with?
Lyne.ai integrates with all major cold email and outbound platforms. All integrations are available on both the free and Custom plans. Users typically export personalised lines as a CSV variable and import them into their sequencing tool of choice.
Do unused Lyne credits expire?
On the free pay-as-you-go plan, credits do not expire. On the Custom plan, unused monthly credits roll over to the next month, so teams with variable outbound volume do not lose allocation they have paid for.
