想要使用Swift 3.0发送自定义电子邮件，即来自Firebase的欢迎邮件

Question

I am using Firebase as my backend in one of my project. I want to send an email to the recipient whenever he is added into the group. Below is the structure of my DB.

Main Group
-----Root
       -----Users
               ---- Friend-1
               ---- Friend-2
        .
        .
        and so on

What I want is to trigger an email whenever a new friend is added in the group Users. I searched and found 3 types of emails supported by firebase but that is only for the main users which are seen in Authentication tab on console.

Answer 1

You can either send email directly from the phone, as described here: How can I send mail from an iPhone application

Alternatively, you can send email from the Firebase servers by using Cloud Functions for Firebase. Your use-case is closest to the Send confirmation emails to users subscribing/unsubscribing to a newsletter. sample in the list of use-cases.
