Letterbird is a web service from Good Enough that makes it easy to create a simple, well-designed email contact form without building a website or setting up a form yourself. Users provide their name and email address, then receive a personal form at a shareable web address within seconds. The service offers a convenient alternative to publishing a personal email address, helping users avoid exposing it to spammers while giving visitors a more polished way to get in touch. Letterbird forms can also be embedded on an existing website using a simple copy-and-paste script, making them suitable for personal projects, activities, and business support.

The basic contact form is free and includes personalization and embedding. A paid Pro subscription, available for $3 per month or $25 per year, adds custom form fields, email attachments, layout options, custom CSS, and the ability to remove Letterbird branding. Good Enough describes its goal as providing a straightforward contact form without unnecessary complexity, and invites users to contact the team by email, Mastodon, or Bluesky.
