The company's research found that spam levels in 2008 remained largely unchanged compared with the previous year, making up between 90 and 95 per cent of total email attempts.
However, the growing use of botnets could push this figure over the 95 per cent mark next year, according to Barracuda.
"As the end of the year quickly approaches, many are asking if spam levels can get any worse in the new year," said Stephen Pao, vice president of product management at Barracuda.
"There are a couple factors that we predict may cause spam to increase slightly in 2009, but it is equally important to note that the level of legitimate email is also increasing each year."
