I have been trying to advertise via emails regarding my pearl jewellery business.
Initially I used mail chimp but was able to send only 2000 emails for free. Later I developed a program myself using amazon mail and sent over 50k emails.
But, my domain was reported as spam sender and sometimes, it is still that way. All this happened few years ago but I am still facing the same issue from Google.
Any way to get out of this hole? Help and advise would be appreciated.
