Nikki Kitchen, who practises witchcraft and runs White Trinity Witch in Plymouth, said Pro-Christian leaflets were pushed through the door.
Anonymous handwritten notes have also been delivered to the shop.
Ms Kitchen previously had to stop running a stall in Plymouth's indoor market because of abusive comments.
Ms Kitchen said: "Churchgoers think we're the spawn of Satan.
"It's been quite harsh and heavy but you've got to laugh it off.'Lost eternity'
"They expect us to accept their religion but they don't look at Paganism as being one of the oldest religions going.
"I think people are just uneducated, it's not about devil worship at all.
"It's about love light and using the earth to heal the people around us."
Ms Kitchen said her shop in Plymouth's Frankfort Gate, sold items for "witchcraft, Paganism, Wicca and all sorts of spiritual religions."
The shop has had religious leaflets and anonymous handwritten notes pushed through the door about five times since it opened in October 2010.
Ms Kitchen said she had not reported the leaflets to the police but had emailed the company behind them to complain and had heard nothing back.
Dr Theodore Danson-Smith who runs a company which distributes leaflets like Ms Kitchen received, told BBC Radio Devon: "We don't sell any hate mail whatsoever.
"It's not hate mail, it's telling the way of salvation.
"Any witchcraft shop is working for Satan not for God."
He said he did not know which Christian group had posted the leaflets, which are entitled "The Beast" and written in comic book form, through Mrs Kitchen's door.
"I don't know who they are but God bless them, they're wanting to save her from going to a lost eternity."
