10 examples of messages to announce a change of professional email address

A poorly communicated professional email address change leads to message losses, disruptions in client follow-up, and security vulnerabilities. Each message should specify the old address, the new one, the effective date, and a verification channel. Here are ten templates written to cover the concrete cases you will encounter, from client emails to internal messages and notifications to service providers.

1. Client notification with anti-fraud warning

Business email compromise attacks specifically target emails announcing a change of contact details. Your clients should be able to verify the authenticity of your message before updating their address books.

Subject: Change of our email address – [Company Name]

“Hello [First Name], as of [date], our contact address will change from [[email protected]] to [[email protected]]. No password or authentication code will ever be requested in response to this email. If in doubt, please contact us by phone at [usual number]. Thank you for updating your contacts. Best regards, [Signature]”

We recommend consulting examples of professional email address change messages to adjust the level of formality to the industry of your recipients.

2. Internal email to the team for domain migration

During a domain migration, all employees must know when the old domain will stop redirecting messages. Technical precision avoids gray areas.

Subject: Email migration – changing from @old-domain.fr to @new-domain.fr on [date]

“Hello everyone, our email will switch to the domain @new-domain.fr on [date]. The old domain will redirect incoming emails for 90 days, after which it will be disabled. Please remember to update your signatures and linked accounts (CRM, billing, SaaS tools). For any technical questions, contact [First Name, IT department]. Best regards, [Management / IT]”

3. Supplier message with billing update

A supplier sending invoices to an outdated address creates a delay in accounting processing. This template explicitly links the email address change to the billing chain.

Subject: New email address for sending your invoices – [Company]

“Dear Sir/Madam, starting from [date], please send all your invoices and contractual documents to [[email protected]] instead of [[email protected]]. Our client references remain unchanged: [number]. Any invoice sent to the old address after [date] may not be processed. We kindly ask you to confirm receipt of this change. Best regards, [Signature]”

4. Institutional partner notification with backup channels

For public organizations or institutional partners, formality is essential. We recommend systematically indicating a backup channel (phone, secure portal) in case of non-receipt.

Subject: Change of official email address – [Organization / Company]

“Dear Sir/Madam, we inform you that the address [[email protected]] will be replaced by [[email protected]] as of [date]. If you do not receive a confirmation of receipt within five working days, please contact us via our telephone switchboard at [number] or through the portal [URL portal]. Sincerely, [Signature]”

5. Automatic redirect response on the old inbox

The automatic response serves as a safety net to catch senders who may not have received your notification. It should remain active as long as the redirect is in place.

“Hello, this email address is no longer active. Please resend your message to [[email protected]]. The automatic redirect will be disabled on [date]. For any urgent matters, contact us at [phone]. Best regards, [Name / Department]”

6. Personalized email to a strategic client

A high-stakes client deserves a personalized message, not a mass send. The tone is direct, and mentioning the ongoing project follow-up reassures continuity.

Subject: [First Name], new address for our communications

“Hello [First Name], as part of the evolution of our infrastructure, my professional address is changing. You can now reach me at [[email protected]]. The follow-up on your file [project reference] will continue without interruption. Please feel free to save this address for our future communications. Best regards, [Signature]”

7. Announcement of email address change on LinkedIn

LinkedIn remains the preferred channel to reach an extensive professional network. The short format requires getting to the useful information in two sentences.

“Change of contact details: my professional address will change to [[email protected]] as of [date]. Please update your contacts so that our communications do not get lost. For any questions, my LinkedIn profile remains the permanent point of contact.”

8. Group notification to newsletter subscribers

When the sending address of your newsletter changes, the main risk is being marked as spam. The message should anticipate this situation and provide a concrete action for the recipient.

Subject: Our sending address is changing – add us to your contacts

“Hello, our upcoming emails will be sent from [[email protected]] instead of [[email protected]]. To continue receiving our communications without them ending up in your spam folder, please add [[email protected]] to your address book. If you do not receive our next email scheduled for [date], please check your spam folder. Thank you for your loyalty, [Signature]”

9. Email to external legal or accounting service

Accounting and legal firms handle sensitive documents. The notification must explicitly list the types of documents concerned to avoid any ambiguity.

Subject: Update of our email address for sending confidential documents

“Dear Sir/Madam, starting from [date], please send all the following documents to [[email protected]]:

  • Tax returns and financial statements
  • Contracts and amendments in the process of drafting
  • Correspondence related to potential disputes

The address [[email protected]] will no longer be monitored after [deadline]. We kindly ask you to confirm receipt of this change. Best regards, [Signature]”

10. Targeted follow-up for recipients who have not acknowledged receipt

A first notification is not always sufficient. The follow-up should mention the date of the first send and remind the deactivation date of the old address to create a sense of legitimate urgency.

Subject: Reminder – our email address has changed since [date]

“Hello [First Name], we informed you on [date of the first email] about the change of our address from [[email protected]] to [[email protected]]. The old address will be permanently disabled on [deadline]. Please update your contacts and confirm receipt by replying to this email. Best regards, [Signature]”

The common point of these ten messages: each contains the old address, the new one, an effective date, and an alternative verification channel. Adjust the level of formality to the recipient, but never sacrifice the anti-fraud mention for your external contacts. A well-structured professional email address change message protects both the business relationship and the security of your exchanges.
