Yes, Mailsuite tracks emails in Outlook: there's a free native add-in. Which tool you use depends on the email client you send from.
Outlook
Yes, Mailsuite works with Outlook. There's a native add-in: free, with unlimited tracking, for Outlook on the web and the Outlook desktop apps on Windows and Mac. You don't need anything else installed — just the add-in.

Gmail
Mailtrack® is the email tracker for Gmail: a Chrome extension on your computer, and the Mailtrack app on your phone.
Other email clients
Yahoo, iCloud, or an address on your own domain: if you add that address to Gmail as a "Send mail as" address, you can write from Gmail, pick it in the From field, and Mailtrack tracks the email like any other.
Google is retiring this. From January 2027, Gmail no longer supports Send as for third-party addresses such as @yahoo.com or @outlook.com. If yours is an Outlook address, the add-in above replaces it and works better. For other providers there is no supported way to track from Gmail after that date.
Send emails from a different address or alias
Did you set up Gmailify?
Google is also retiring Gmailify and POP fetching. New setups are no longer possible, and existing ones end in January 2027. Outlook addresses can move to the add-in above; for other providers there is no replacement.
