How to set up a second Gmail account for AI.
By Vamsi Krishna · Updated
Make an account for the purpose, use a filter to forward only the mail you are willing to share into it, then connect the AI tool to that account. It costs nothing and works today. The trade is upkeep and duplicate mail.
The setup
- Create the new Gmail account first.
- In your main account, open Settings, then Forwarding and POP/IMAP, and add the new address. Google sends it a verification link you must click from the new account.
- Leave blanket forwarding off. You want a filter instead.
- Make a filter matching only the mail you will share, and tick Forward it to the new address.
- Connect your AI tool to the new account, never the original.
Why the filter matters
Blanket forwarding copies everything, which defeats the point. The filter is what makes this scoped rather than a second full inbox.
What this does not fix
- You now have two copies. The second account has its own password and its own risk.
- Threading and attachments suffer. Forwarded mail does not always look like the original.
- It only moves forward. Mail that arrived before you set the filter stays where it is.
- New categories need new rules. Every time your needs change, you edit filters by hand.
When it is enough
For one narrow job that rarely changes, like receipts for an accountant, this is a good answer and you should use it. It gets tiring when rules change often or you want several scopes, since each one means another account.
Where allowemail fits
We do this without the second account or the copies: the tool reads a filtered view and never holds your Gmail credential. Early access list.
