How does HeyStranger boost cold email conversion?
HeyStranger makes it easy and affordable for high-volume senders to create hyper-personalized cold emails at scale. Unlike with generic templates, you can mention a prospect's product, service, create warm introductions, PS compliments, and more; all proven to increase response rates and booked meetings.
Where does HeyStranger find information on prospects that are accurate?
For the majority of contacts, we are able to gather sufficient information from their business' websites, blogs, and related articles.
What results can I expect?
Internally, we've seen some campaigns reach up to 6% response rates, 3x meetings booked compared to generic copy, and recipients asking how we knew certain information about their company. However, HeyStranger is a tool like any other piece of software, and works as well as you use it. We've tried hard to make it easy for anyone to create hyper-personalized cold email copy, but if you still have questions feel free to reach out and we can write copy with you.
Can you audit our cold email system?
Yes, HeyStranger customers get access to our team of experienced copywriters, GTM engineers, and cold email managers to help you along any step of your cold email process.
