How to Send Templated Emails with JavaScript While Overcoming Browser URL Character Limitations?

Email Sending with Javascript: Client-Side Approach

This article addresses the issue of sending templated emails through a website, but utilizing the user's local mail client for the actual transmission. The objective is to avoid server-side email sending and provide users with a customizable email draft that they can edit and send from their preferred email application.

One suggested approach involves creating a simple HTML interface with a text area for the email body and a button to initiate the mail composition process. The Javascript function handles the creation of a mailto URL, specifying the email recipient, subject, and body. When the button is clicked, the Javascript function assembles the URL and redirects the user's browser to open their local mail client with the predrafted email.

While this method offers simplicity and convenience, the downside lies in the potential character limitations for the email body. If the email content exceeds a specific threshold, the email may open but remain empty. This is likely due to the maximum URL length restrictions encountered by many web browsers.

Therefore, the key challenge in this context is finding a way to maintain email template functionality while accommodating longer email bodies without encountering browser URL limitations.
