The so-called friends are essentially other Salesforge clients with whom you're talking about various stuff in business whether it's about a product or booking a meeting. Be sure that they always open your emails and even reply back just like friends would do.
The unique emails written by AI signal to email service providers that these are legitimate inboxes rather than being used for phishing or anything else.
When you then will reach out to your prospects cold, the likelihood drastically increases of being able to land in the primary inbox of the recipient rather than any other folder.
