Lyne has saved my agency time and money so we could focus on other parts of our strategy that we're tackling. Using Lyne allowed us to scale with less resources and for cheaper.

Lyne has helped me save tons of time and money compared to before when I was outsourcing my first line writing to freelancers who would take days or weeks to finish what Lyne can do in half an hour.

Frequently Asked Questions

How much post-editing is required with Lyne?

Currently we have 2 main systems: Lyne Classic & No-Touch Lynes. Lyne Classic gives you access to things like personal content Lynes. The data is rich, but there is a ~5% error rate.
No-Touch Lynes have less rich data but will have no errors and are ideal for full automation. All they require is you give us a LinkedIn URL.

How does pay-as-you-go billing work?

You’re charged in increments of 20 credits, at $6 per 20 credits.

How do Lyne credits work?

Simple. 1 credit = 1 personalized contact with at least 2 intro lines. The more we can find, the more personalization types we provide, up to 12 total.

Does Lyne work with Gmail addresses?

At the moment we aren’t able to work with Gmail addresses and require business email addresses or LinkedIn profiles.

What data does Lyne need to start?

A simple rule to keep in mind is that the more data you provide, the better the output will be. However, Lyne only needs a list of emails or LinkedIn profiles to get started.
