You have chosen to sponsor your bid up to a maximum amount of .
I have around 350,000 contacts that I need to regularly send emails too.
Most of them have yahoo and gmail accounts and so the emails have been ending up in their junk box.
I need to find a permanent solution and need to email to them without ending up in the junk box.
Please DO NOT reply if you are not sure how I can get the emails in the inbox. It has been very frustrating hiring people and when they are done emails are still delivered to junkbox.
Part of the problem is that when too many emails are sent to gmail and yahoo with the same email/IP and same content then they consider it junk.
What would be ideal is for someone to have email sending program with many rotating IP's who have good reputation with gmail and yahoo. This software should know to send limited number of emails to each email server at a time (eg send only 30 emails for yahoo per minute).
Payment is only upon successfully sending emails to inbox. I will listen to all suggestions.
