How to Convert a Personal Gmail Habit Into a Business Domain Habit

You have the domain and the mailbox, and you still reply from Gmail because that is where the thread was. Converting the habit is a 90-day project, not a switch: contacts and signature move on day one, the old address forwards for three months, and every reply from the new address retrains one more customer. Here is the plan with the exact steps.

Quick summary

• Create your mailbox on the domain (you@yourcompany.com) and the role addresses you will publish (hello@, support@). On OquMail these are free, with webmail and IMAP for any app.
• Add the new account to every device you use, with the OquMail settings: IMAP mail.oqumail.com port 993 SSL/TLS; SMTP mail.oqumail.com port 587 STARTTLS.
• Set it as the default account on your phone and desktop app so new messages start from it.
• Move your signature over and update it with the new address. Delete the signature from the Gmail account so replies from there look unfinished, which nudges you to switch.
• Export contacts from Gmail (Google Contacts, Export, vCard) and import them into your mail app or webmail contacts on the new account.

Day 1: make the new address the easier one to use

1. Create your mailbox on the domain (you@yourcompany.com) and the role addresses you will publish (hello@, support@). On OquMail these are free, with webmail and IMAP for any app.
2. Add the new account to every device you use, with the OquMail settings: IMAP mail.oqumail.com port 993 SSL/TLS; SMTP mail.oqumail.com port 587 STARTTLS.
3. Set it as the default account on your phone and desktop app so new messages start from it.
4. Move your signature over and update it with the new address. Delete the signature from the Gmail account so replies from there look unfinished, which nudges you to switch.
5. Export contacts from Gmail (Google Contacts, Export, vCard) and import them into your mail app or webmail contacts on the new account.

Day 1: forward the old address, then answer from the new one

1. In Gmail, Settings, Forwarding and POP/IMAP, Add a forwarding address, enter you@yourcompany.com, confirm the code Gmail sends there, then choose "Forward a copy" and keep Gmail's copy in Inbox for now.
2. Alternatively, add the Gmail account to your desktop app over IMAP so its mail appears alongside the new one, and reply from the new identity.
3. Rule for yourself: every reply goes from the new address, even when the thread started in Gmail. Change the From field before typing. The recipient's next message comes to the new address and the thread migrates itself.
4. Add a line to your signature for 90 days: "New address: you@yourcompany.com. Please update your contacts."

Weeks 1 to 4: move the logins

• Go through your password manager or the "accounts" folder and change the login email on every business service to the new address, starting with the domain registrar, bank, accounting and payment tools.
• Update the address on your website, invoices, social profiles, directories and business cards.
• Tell your top twenty contacts directly, in a normal reply rather than a mass announcement.
• Watch what still arrives at Gmail. Each item is a login or a contact you have not moved yet; fix it the same day.

Weeks 5 to 12: sunset

• Set a Gmail vacation responder: "This address is no longer used for Yourcompany. Please write to you@yourcompany.com." Keep forwarding on.
• Stop checking Gmail directly; everything reaches the new mailbox.
• At day 90, review a month of forwarded mail. If it is only newsletters and spam, turn off forwarding, leave the responder on, and treat the account as personal only.
• Do not delete the Google account; it may still be the recovery address for something you missed.

Why forwarding is a bridge, not a home

Mail forwarded from Gmail arrives at your domain with Gmail's rewritten envelope, which works, but replies you send from the domain are what actually move customers. Forwarding indefinitely means the old address stays alive in everyone's contacts, spam keeps flowing through it, and one day Google's account rules or a forgotten password cut it off. The point of the 90 days is to let it go.

Common questions

Should I import my old Gmail history into the new mailbox?

Import the last year or the threads you still work with. Add both accounts to Thunderbird over IMAP and drag folders across; leave older history in an exported archive rather than filling the new mailbox with it.

What about the personal contacts mixed into Gmail?

Export everything, import into the business address book, then delete the obviously personal entries from the business side. Personal contacts stay in Gmail, which becomes what it should have been all along.

Clients keep replying to the Gmail address. What now?

Keep replying from the domain and check the From field every time. Most contact lists update on the first reply; a few people will need the signature line and one polite mention. After 90 days the vacation responder does the rest.
