A mass email reportedly addressed all recipients as ‘Michael’, prompting fears that personal details had been compromised by the company.
The insurer instead blamed the mistake on a “technical error”, and said that there were “no wider privacy issues” at hand.
The mistake affected its general insurance and life customers.
In a statement, the insurance group said: “We sent out some emails to existing customers, which, as a result of a temporary technical error in our mailing template, mistakenly referred to customers as ‘Michael’.
“We’ve apologised to these customers and reassured them that the only error in the email was the use of the incorrect name as a greeting. There was no issue with personal data; the remainder of the email and its content was correct.”
