I use Gmail at home and at work. When I create work-related emails, I need to change the From field to my work email.

Since I have regular people to whom I send work related emails, I would like an option that when I choose a work related person in the To field, the From field will automatically change to my work email address.
Does such option exist?


I assume you're receiving email to only one address, so that both your work and home contacts use the same address to contact you. If so, you cannot automatically set the From field when sending emails.

But if you had two addresses for people contacting you, you could setup default From addresses. When replying to an email, a From address is chosen based on which address was used to receive the message.

Such a scheme means you would need to inform your contacts to use a specific address for work/home related emails. You could use, say eyalev+home@gmail.com and eyalev+work@gmail.com - anything after the + sign is ignored by Gmail.

Then enter your Gmail settings, and go to the Accounts and import tab. Under Send mail as add new accounts for eyalev+home@gmail.com and eyalev+work@gmail.com. Take note of the Treat as an alias option to get the behaviour you want.

Also see the official guide to using 'plus' addresses.

  • That's aaaaaalmost perfect. I'd like not just replies but new email conversations to also do this detection. – mcandre Oct 16 '12 at 15:23
  • Now that, I don't think is possible. – Vidar S. Ramdal Oct 16 '12 at 18:47
  • Merf. Well, thanks for detailing what we can do. – mcandre Oct 16 '12 at 19:50
  • I don't have this problem when replying to emails, only when composing new ones. – Eyal Levin Feb 28 '13 at 8:22

I don't think there is. But I don't think either that changing the from field is that hard, is it? It's a simple select box.
