“Letterbase puts user interaction right at hand when the user needs it most.

As a founder of a focused privacy service, it was important for me to adopt a user interaction system that cares as much about user privacy as I do.”

1. Why should I use Letterbase? Can't I just use a mailto link or a contact form?

Mailto links and contact forms are like sending a message by horse and buggy. Letterbase is like giving your website visitors an absurdly convenient teleportation portal.

This increases the dialogue that you can have with your website visitors, which is crucial for the success of your business.

You can use it to convert more customers, get more valuable feedback, get notified of issues ASAP, and more.

Plus, having Letterbase on your website is a sign that you care about your customers, which is something that they will appreciate.

2. How are you privacy-friendly?

With Letterbase, you have full ownership and control of your data. We don't sell your data, we don't advertise to you, and we don't share or collect data unless it's absolutely necessary.

You can try Letterbase for free for 14 days—no credit card required.
