What is this tool?

The bottleneck this removes is writing a personalised first line for several hundred cold emails a week. Upload emails or LinkedIn URLs, and it researches each row and returns an opener with a matching subject line, ready to merge into the sequencer you already run. Top-ups at $6 per 20 credits, charged only on rows that produce output, make a real batch cheap to test — worth doing before any subscription, since the two monthly cards are ambiguous and the 2021 privacy policy covers none of the scraping the product now does.

Read full overview

Getting prospects in is the first stage: upload a CSV of emails or LinkedIn profile URLs, or scrape a Sales Navigator search with the Chrome extension. The second is research — Lyne works through the rows in the cloud and notifies you when the batch is done, which is why the product is sized for lists of hundreds rather than for one message at a time. The third is routing the lines onwards: the integrations page lists Lemlist, Mailshake, Woodpecker, Wavo.co, Hunter, Snov.io, Reply.io and Close.com, each described as automating cold outreach, or you download a CSV and merge the columns yourself. Whether a batch needs a review pass between the second and third stage depends on which line type you ran.

The pricing page is where this gets confusing. A $0 card marked Forever charges per credit with no monthly fee, and beside it sit two monthly cards at $120 and $39 that are both titled Custom; the $120 card prints 'Credits Roll over' and '$0.25 / lyne' next to '2000 Emails / month' and 'Unlimited Lynes / month', so read it as a card that needs a vendor conversation rather than a plan you can size from the page. Subscriptions are self-managed through Stripe, monthly or yearly. The privacy policy names Lyne.ai LLC, gives a right to deletion on request and allows sharing with partners for statistical analysis, but it predates the scraping and enrichment the product now sells and says nothing about them, about retention periods, or about certifications.

Is this right for you?

Quick fit check against how you actually work.

ai email writer

Choose this if

You already run cold email through one of the eight listed sequencers or CRMs and want researched openers dropped in as merge fields rather than written by hand
Your lists come from LinkedIn Sales Navigator and you want scraping, email finding and personalisation in one workflow
You want to pay per row of output and try a small batch before committing to any subscription
Some of your sequences run fully unattended and you can accept plainer No-Touch lines where nobody reviews before send

Consider alternatives if

You need to know exactly what a subscription includes before buying, because neither of the two monthly cards can be sized from what the pricing page prints
You need a data-handling statement covering scraped prospect data, a retention period or a commitment on model training; the privacy policy, effective February 2021, addresses none of these
You depend on responsive vendor support: a few commenters on Lyne's own demo videos in 2022 and 2023 reported failed list runs, no reachable support channel and a purchase they could not complete, thin and dated evidence but worth testing before you load credits
You send low volumes or write each email yourself, because the value here is in batches of hundreds of rows, not in polishing one message

Key features

What you can actually do with this tool.

One row in, one researched opener out

Give it a list of emails or LinkedIn profile URLs and it scans each prospect and company, then returns intro lines per row. The vendor quotes up to 1000 intros an hour and processing runs in the cloud, so a list of several hundred rows completes as one batch rather than row by row, and more input columns give better lines.

Classic lines or No-Touch lines, chosen per campaign

Classic pulls richer personal content such as blog posts, case studies and podcast appearances and carries a stated error rate of around 5%, so the vendor tells you to review before sending. No-Touch needs only a LinkedIn URL, is plainer, and is built to go out unreviewed in fully automated sequences.

Subject lines and up to 12 personalisation points

The output is not just a first line: each prospect gets a matching subject line and multiple personalisation variables, which the vendor's own templates use as merge fields like {{subject_lyne}} and {{case_study_lyne}} across email and other channels.

Credits are spent only on rows with output

One credit buys one personalised row, a row can hold several lines, and no credit is charged when nothing usable is found for a prospect. That makes cost roughly proportional to the leads you can actually personalise rather than to list size.

Sales Navigator scraping with email finding

The Chrome extension extracts a Sales Navigator search in one click, finds and validates professional emails, keeps running in the cloud after you close the tab, and hands the results to the personalisation step or exports a CSV.

Frequently asked

Common questions about this tool, answered.

Does Lyne write the subject line as well as the first line?

Yes. According to the vendor, each prospect gets a matching subject line plus as many as a dozen personalisation variables, and its own template examples open with a {{subject_lyne}} merge field followed by a body line such as {{case_study_lyne}}.

How much editing do the lines need?

It depends on which system you run. Lyne Classic gives richer, personal-content lines with a stated error rate of about 5%, and the vendor recommends reviewing a batch before a campaign, quoting roughly 15 minutes per 300 lines. No-Touch Lynes are plainer, need only a LinkedIn URL, and are stated to need no review, which is the mode to use for fully automated sequences.

Can I use Lyne.ai without a subscription?

The pricing page prints a $0 Forever card that is pay as you go with no monthly charges, and top-ups are charged in increments of 20 credits at $6 per 20. The home page shows 'Try for free' and 'Start Free Trial' buttons, but neither it nor the pricing page attaches a length or a credit count to them, so treat any free allowance as unconfirmed until you see it in your account.
