don't worry for that, this the process that i use with cold emails b2c list
* try to segment the list (you don't need to do that because your leads is related to your niche
* create emails using templates that call the atention, i use a platfrom that shows me the ebst emails, thanks to that i copy the best one and edit with my information.
* create subscriber list by segmentations
* try to send emails using different domains (i suggestion domains related to the niche no your brand)
is a games numbers with cold email list, send as many as you can, keep the ones tht open, cliack and reply, delete the ones that do not show any sign of a human being checking the email.
