COLD EMAIL LIST

Topic summary

The discussion addresses strategies for sending emails to a large cold email list while avoiding spam filters and deliverability issues.

Recommended Approach:

  • Warm up the list gradually rather than sending to everyone at once
  • Start by segmenting the list and sending to small portions initially
  • Monitor key metrics including engagement rates and bounce rates after each send
  • Once metrics are within acceptable ranges, progressively increase the volume
  • Scale up sending gradually to build sender reputation

This phased approach helps establish credibility with email providers and reduces the risk of being flagged as spam.

What is the best way to send emails with a pretty big cold email list without it going to spam or being flagged?

If you have a cold email list, you have to warm up the list. I’ve often broken up the list into small parts at first to see how the list responds. Once you sent to a small percentage of your list, you can then measure engagement, bounce rate, etc. Once those numbers are under control, you can then start to add more of your list gradually, slowing warming up your cold list.
