Integrating ServiceM8 with your Google Apps account allows you to send emails to your customers with your real email address as the "From" address.
Activate the Google Apps Integration add-on in Settings > ServiceM8 Add-ons
This will start the Connect wizard. Follow the steps to connect your Google Apps account.
Test it out by sending an email from inside ServiceM8
The email is delivered from your real email address. You'll also be able to see it in your Gmail Sent Items folder.
Please note that ALL email sent from any user in your ServiceM8 account will be delivered from the connected Google account's email address. For this reason, we recommend that you connect your ServiceM8 account to a company-wide email address rather than a staff email address.
