Introduction and organisation: communication: communicating by external email: signing your emails
Your signature at the bottom of your emails must be appropriate. You should add the following to the end of your signature for any external emails:
‘If you have any doubt about the authenticity of an email you receive which claims to come from HM Revenue & Customs (HMRC), please do not follow any links within the email, disclose any personal details or respond to it. Forward it to us at firstname.lastname@example.org’
We recommend having two signatures, one for internal emails and another for external.
Also, be aware that out of office messages do not go to non-GSI email addresses, so customers will not receive them. You may wish to consider granting delegate access to a colleague. Refer to the Electronic Communications Email Guidance for further assistance.
