You can send a Group Email to multiple Contacts on iPhone by opening a New Message in the Gmail App and manually selecting the Contacts that you want to send the Email to.
However, manually adding Contacts to Email Message is time consuming and not suitable, if you are frequently required to send Email Messages to a large Group of people.
In such cases, the most efficient way to send Group Email Messages is to create a Contact Group containing all the recipients and address your Email Message to this Contact Group.
Send Group Email Using Gmail App on iPhone
As mentioned above, the first step is to create a Contact Group, containing the people or the recipients that you frequently send Group Email messages to.
While you can create the Contact Group using the Contacts App on iPhone, this Group won’t be recognized by the Gmail App. Hence, the only available option in this case is to create the Contact Group by logging in to your Gmail Account on a computer.
Once the Contact Group is ready, you can sync Gmail Contacts to iPhone and this will make the Contact Group available for selection, while sending Email messages from iPhone using the Gmail App.
