One of the most popular email services, Gmail keeps track of all your emails with threaded conversations, tags, and Google-powered search to find any message you need.
Send each approved notice with the right customer details and track exceptions.
Your customer notices go through your work email with account details from your spreadsheet, and send results stay beside customer rows.
Send each approved customer text on time and report its result.
Your personalized customer texts reach the sending service when due, and a reply tells you what happened or needs attention.
