Don't close Gmail on day one, ease into it

You'll know whether to forward or manually check your old Gmail, how long to keep it active, and what auto-reply to leave before actually closing it.

You write to your clients from your own domain now. But that old Gmail account is still out there, and mail still finds it: a client who saved your info three years ago, an old invoice with that address, someone who booked with you before the switch and never got the memo. You've already decided to stop using it for business. What's left to figure out is what to do with the account itself: close it right away, keep it forwarding everything forever, or check it now and then. And mainly, for how long.

Closing it the same day you switch domains is a common mistake, and a costly one. An email sent to a closed address bounces back to the sender with a technical error notice that most people never read or understand: as far as they're concerned, you just never replied. You lose the appointment, the order, or the client, without even knowing they existed.

Forward it or check it by hand: the only decision that matters at the start

You don't need to keep an eye on two inboxes. There are two ways to cover yourself while word of the change reaches everyone, and which one you pick depends on how much you rely on what lands there.

How to cover your old Gmail

Automatic forwarding to your new account

Anything that lands in Gmail shows up in your new inbox too, so you're not checking two accounts every day.
Gmail forwards everything new except what it flags as spam: check that folder once in a while.

Manual check, once a week

Log into Gmail once a week, spend two minutes, and reply only to what's worth it.
It forces you to see who's still writing there, and that's what tells you when you can finally close it.

Which one should you pick: If your business runs on appointments or orders, turn on forwarding: you can't afford to lose a client just because you didn't check a second inbox. If it's a low-key business and the gmail only gets stray noise, check it by hand once a week and skip the hassle of setting up forwarding.

How long to keep it alive

The old account doesn't empty out all at once, it drains little by little. At first it still gets most of what it used to, since people write to the last address they had saved, not the one you prefer now. Over the following months, less and less mail shows up there, and more of it comes from people who hadn't written to you in a long time.

Example: out of every 100 emails that used to land in your Gmail, how many still show up there after the switch

Month 135%

Month 315%

Month 66%

Month 122%

What matters isn't the month on the calendar, it's the number: once you've gone two or three months straight without getting anything but spam, you can close it. Before that, closing it means betting that no one important is going to write there, and it's a bet you don't need to make.

The costly mistake: closing it to save yourself a step

Closing the old Gmail the moment you turn on the new one, just so you don't have to think about it anymore, is the cheapest way to lose the customer you least expected to lose: the one who's had you saved for years and, for that very reason, takes longer to write to your new address. There's one thing that prevents it: set up an autoresponder announcing the change before you touch anything else, and don't close the account until that autoresponder has gone months without firing.

The notice you leave up in the meantime

Autoresponder on the old Gmail

Thanks for writing. I no longer check this address daily: from now on, you can reach me at info@yourbusiness.com. If it's urgent, write to that address and I'll get back to you today. If you're writing about an appointment or an order, please send it there too so it doesn't get lost among the rest of the mail in this account.

What you walk away with

Decided whether to forward the old Gmail to your new account or check it by hand once a week.
Set up the autoresponder that announces the address change as soon as someone writes there.
Set the real criterion for closing it: once you've gone two or three months without receiving anything but spam, not before, no matter what the calendar says.
