How to Extract Email Addresses from your Gmail Messages
The Gmail Extractor app will automatically extract the email addresses and names of senders from your Gmail account. You can choose to extract email addresses from every single message in your mailbox or from emails that are tagged with a particular Gmail label (or folder).
The extracted email addresses are saved in a Google spreadsheet that you may either download as a CSV file for importing into your mailing list.
If you looking to create an email marketing campaign for your clients who are not in your Google Contacts yet but you have previously communicated with them over email, the email extractor program can help you quickly build such a mailing list.
Here’s how you can use the Gmail extractor to pull emails of sender’s from your Gmail messages:
Click here to copy the email extractor Google sheet into your Google Drive.
Put the Gmail label name in cell A2. You may use inbox for extracting addresses from emails that are in your Inbox, starred for just the important emails, labela-labelb for emails in label B that is a sub-label of Label A or say all for processing all messages in your Gmail account.
Put your email address in Cell B2. The program will send you an email notification here once all the emails for that label have been extracted.
Next click the Gmail Extract menu in the Google sheet and select Initialize. Grant the Google script access to your Gmail mailbox.
The Google script is now running in the background and, depending on the size of your Gmail folder, may take some time to complete. You may close the Google sheet and it will send you an email once the extraction is complete. If there are any duplicate email addresses found during extraction, the program will automatically remove them and will populate the column B with the unique list.
You can stop the Email Extractor anytime later from the same Google Sheet. Choose the Gmail menu and select Uninstall.
