Of course this is a professional cost!
Your postal and shipping costs are deductible for both VAT and income tax, as long as the costs are incurred for a business purpose.
As a company, you will naturally need to send and receive mail, not only through email. So do not forget to deduct your postal letters and your packages (professional, of course): you will see your taxes decrease by a factor of 100%.
