About 332 million emails were blocked every month between January and October this year alone.
According to the telco, that’s more than a third (38 per cent) of all inbound email to Bigpond accounts.
Telstra has a lot of email running through its system.
Last Friday during the Black Friday sales event there was a huge volume of emails promoting specials and offers at shops and websites all around Australia and the world.
On that day alone Telstra’s email system processed more than 56 million emails, 75 per cent higher than an average Friday.
Not all Telstra customers will be using Bigpond email, with many opting for independent third party systems like Gmail or Outlook Mail.

But Telstra has millions of active customers using Bigpond so there’s a definite impact on average Australians with this scam filtering system.
Those 332 million emails sit alongside the up to 15 million scam phone calls each month being blocked by Telstra, and the 61 million scam SMS messages.
