When I receive an email from a prospective client in my Gmail inbox, I place a specific label on it according to the query.
Is there a way to create a group email easily to send out to all recipients who are under the same label? In the past I have had to bring up the label, hand write the email address down and manually create a group in contacts and add each email address to be able to send out an email to all recipients in a particular label.
Presently, there's no way to compose a new group email based on conversations in a label.
You can however, create a Contact group from an email message, rather than navigating to the Contacts page.
Compose a new message in Gmail and enter the email addresses of all intended recipients in the To field.
Alternatively, Navigate to your label, select a conversation with all recipients and click Reply all, and ensure all email recipients are in the To field (cc or bcc will also work).
Click To to select contacts.
From the pop up, click Save as group... and enter a name for your group.
Compose a new message. In the To field, enter the name of your group and select the group from the autofill results.
If you want to remove members from or add members to the Group you created this way, you will have to do that via Google Contacts. Or, you can follow the steps above to create a new group with the new composition of recipients.
You can inspect the page using developer tools in chrome, get the table element as html, then use sublime text to regex find with email="(.?)@(.?)" then you can hit 'find all' and cut out all the email address and paste them into a new document. Then in sublime text go in the menu edit -> permute lines -> unique and it will remove duplicates. Then you can copy the list into a new email.
