Email Sending

Last updated: May 13, 2026

Here you will learn how to use emails in the post-processing of calls with fonio.

In this article, you will learn step by step how to automatically post-process calls via email with fonio. For example, you can have the transcript or specific information sent dynamically by email as soon as fonio has handled a call for you.

How it works

  1. Set Subject
    Open the email post-processing. First, you need to set a subject for the email.

  2. Define Recipients
    When selecting recipients, you have 2 options:

    1. Static recipients: Here you simply specify the email address(es) to which the email should be sent.

    2. Dynamic recipients: Here you can dynamically define under which conditions the email should be sent to which recipient. You can create your own prompt specifying exactly how emails should be sent.

  3. Set Email Content
    There are again 2 options to define the content of the email:

    1. Standard: Here you can set a fixed message that is always sent. You can use various variables here that were extracted during the call or are otherwise available. Variables from the inbound webhook or the context of the outbound API calls can also be inserted using context.variable.

    2. Custom prompt: Here you can specify what should be included in the message. You write a prompt with which the AI, based on the transcript, composes an individual email.

    3. Practical example of a custom prompt: Create an email notification stating, “Email address unclear, please check the audio file at [timestamp],” if the caller's email address was not clearly understood.

  1. Save & Test
    Now you can save your post-processing and test it directly in the browser. During test calls, all post-processing steps will also be executed, provided the necessary conditions are met.

Tip

Important: It often makes sense to create multiple email post-processings. This is generally possible and not a problem. It is especially important here to be clear about the conditions under which which email should be sent.
