No. You will have to carry the hardcopy or a printout of the e-visa that you receive on your email. The websites send the visa on the email address you provide, but it is your job to ensure that you get the printout of it. The airport security or the immigration department will not accept the softcopy of the document. It is against the rules and regulations, as well. So, whenever you receive the e-visa, get the hardcopy of it immediately.
