Sending volume per inbox needs to be capped at a maximum of 30 emails per day. Meaning, if you want to send 10,000 emails per day, it equates to 333 inboxes. That is precisely how many we had (before we started scaling to 30,000 sends per day).
Because domains needs to have SPF, DKIM, and DMARC records, they need to be set up through an ESP, such as Microsoft Outlook, which is what we use.
We connect these inboxes to
SmartLead, and get our lead lists & scrape emails from
ListKit.
An Admin Panel on Microsoft Outlook should have a maximum of 10 domains within it, and a domain should have a maximum of 2 inboxes housed within it.
This is because if one inbox gets marked as spam too frequently, the entire domain burns. So if you had all of your inboxes on one domain, every single one would burn.
It is not a question of IF a domain will burn, it is a question of WHEN.
DO NOT cold email unless you create the infrastructure like this.
It's also important to note that you don't have to immediately start with 10k per day. You can get 10 domains, with 20 inboxes, and start small. You will get results if your offer is good.
