Exeter-based airline, Flybe, have been fined for sending millions of unwanted emails.
Last August Flybe sent out an email titled " are your details correct" advising people to amend any out of date information and update any marketing preferences.
It also instructed people that by updating their preferences they might be entered into a prize draw.
But a person who received it explained that they had previously opted out of marketing e-mails from Flybe. The firm said they had sent 3.7 million emails.
The Information Commissioner says the contravention of the rules is serious and fined the firm £70,000.
Flybe say they cooperated fully with the investigation and would like to sincerely apologise to those customers affected.
