Frequently Asked Questions

Answers to common inquiries about URL encoding rules and mailto link standards

How do mailto links work?
A mailto link is a standard HTML link protocol (e.g. mailto:[email protected]) that triggers the default email client (like Outlook, Gmail, or Apple Mail) on the user device, pre-populating fields automatically.
What is the character limit for mailto links?
While mailto syntax supports large prefilled bodies, most browsers and email clients enforce a URL length limit of 2,000 characters. Keeping bodies under 1,500 characters guarantees full compatibility.
Can I include formatted HTML inside the body?
No. The mailto protocol does not support HTML formatting in the body field. Only plain text and line breaks (encoded as %0A) are compatible with email client interpretations.
