Stop checking two inboxes separately
If checking a work account and a personal account separately feels like a hassle, setting up auto-forwarding lets you read everything from a single inbox instead.
Replying from a forwarded message uses the forwarded address
If you reply directly from the address the mail was forwarded to, the reply goes out under that address's name rather than the original account's -- worth keeping in mind if the recipient needs to see a specific sender address in their reply.
Frequently Asked Questions
Can I reply to a forwarded message?
Yes, but replying directly from the address it was forwarded to sends the reply under that address's name rather than the original account's, so pay attention to which address you're replying from.
Is it safe to set up auto-forwarding?
It's fine as long as you only forward to an address you trust. If you notice a forwarding rule you didn't set up appearing on your account, check your account security immediately, since it's a common sign of unauthorized access.
