Hi, I also need a 3rd party mail server that can handle 500,000 to 1,000.000 emails per day.
Servers IP(s) must be whitelisted/safelisted with the major ISP's: aol, yahoo, gmail, msn/hotmail.
Need 90% inbox rate.
Happy to consider any solution so please outline in detail your proposal.
Please bid on a monthly basis.
Please keep in mind the IP's need to stay safelisted and/or be changed as needed, etc.
Thank you in advance
