Hi,
Hope this finds you well, having been in email infrastructure development for a decade. We primarily setup mail servers for the clients, clients related to different niches, especially from Forex Trading, Gambling, and Crypto. We've managed multiple databases of email records, some are sophisticatedly filtered ones. Open to discuss more if you are looking for more information in the chat.
I can provide you the opens from a forex database as well as for the crypto. Opens are considered to be the most engaged contacts from the list. The list of filtered openers is saved along with different data fields including names for personalization and geographic information as well. I am quoting you 10k records from this list of Forex Openers.
Mailing Solution
--------------------------
It is a more interesting part of your project for us certainly as we primarily setup servers for high volume email delivery with an appropriate set of hardware resources and software tools/applications. Although, for self-hosted mailing infrastructure and in cold emailing, you aren't restricted to certain volumes. But still, every system has certain limitations and we can't burden a system more than its capacity. Let me know more about your mailing, volumes, and hygiene of your list, we can help you set up a self-hosted solution for you to monetize your list with flexibility and send with freedom.
I look forward to your response to discuss this further.
Regards,
