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

No one uses mailto links or contact forms unless they absolutely have to. They're hard to find, and using them feels like you're just flinging your request into the abyss.

On the other hand, Letterbase makes it absurdly convenient and easy for your customers to contact you about anything—questions, feedback, bugs, etc.

Having Letterbase on your website shows your commitment towards providing fantastic customer service, and it's something that your customers will appreciate.

Why is Letterbase better than other tools like Intercom or Crisp?

How are you more privacy-friendly than other tools?

Any messages sent with Letterbase are only handled until they are delivered. We don't store any of your conversations—instead, they're stored with the email provider you already use.

We also do not track your users in any way. In contrast, other tools track what pages specific users have visited or spy in real time on what your users do on your website. We believe these "features" are an invasion of your users' privacy, and we do not collect this kind of data.
