Numbers of IPs and Sending Domains for Cold Outreach


New Member

I am curious to know what would the community recommend regarding the number of IPs & sending domains to be warmed up to perform a cold outreach operation.

What I mean precisely is can I use different domains with 1IP or its better to stick 1 domain for IP.
Is there a recommended sending limit for 1 IP?

I would love to be able to send around 500/1000 per hour without getting blocked by major Email Service Providers.

Right now I am sending 3000 per day over 2 IPs and 2 sending domains, and things are going well. But I would love to speed things up a little bit.
