Have you tried email marketing?

I was hoping to tag this question to my other thread on marketing but it is off the radar now.

I am just wondering has anyone tried email marketing for accountancy services? How did it go in terms of getting appointments? Most of the emails would end up in junk. It may still be worth a try.

I understand you can buy email lists with business email addresses.

I would be grateful to read about your experience/views on this subject.

Thanks
