Question on Bulk Cold Email Sending Using Multiple Domains

I have 10 domains ready to send emails. Goal is 200 emails per day per domain. Will be starting off slow then working my way up to 200.

Big potential issue/question I have with hitting spam triggers is - all domains are on the same shared IP address (using hostgator). With three domains I've been using already, it seems to be doing okay with deliverability. But will having all 10 on the same pose a risk?

Do I need to go the dedicated server route (which I know is quite expensive at around $100 per month) and spread the domains out between multiple servers? Or is there a more cost effective way to do this?

Really appreciate any insight here as it will greatly help the chance of success moving forwards.

Even a shared or dedicated IP's spam triggers due to words or paragraph of email your sending. Make sure your rotational is good or combine multiple SMTPs with individual domains..

You can go with shared ip without any worries.

Good luck

I would advice to also warmup your domains with email warmup services so that you are balancing your activity with your sending, the way these services work is if your email lands in spam/promotion they mark it as not spam so over time your sending reputation increases.
