Frequently Asked Questions
Is this a replacement for Gmail?
No. It works as an automation layer on top of your standard Gmail account, enhancing its capabilities rather than replacing it. Your emails are still sent through your own Gmail account—the tool simply handles repetitive tasks for you.
Do I need another email platform?
No. The entire workflow happens directly in your existing Gmail inbox. There's no need to pay for or learn a separate CRM or email marketing tool just for simple automation.
Can I import a CSV?
Yes. You can import your contact list (e.g., exported from a spreadsheet or CRM) and automatically map fields to personalization variables.
How private is my data?
MailWorker only automates the mechanical steps you'd otherwise do by hand in Gmail. It does not collect your CSV contact list or email content. The extension runs locally in your browser, does not store your Gmail password, and keeps everything under your Google account — with no separate third-party dashboard holding your data.
Can I personalize emails?
Yes. You can use fields such as first name, company, role, or any other columns present in your CSV to create dynamic variables in your email template.
Can I use it for cold outreach?
It can be used for outreach workflows, but users are responsible for complying with applicable laws (like CAN-SPAM), Gmail/Google Workspace sending limits and policies, and recipient consent requirements.
