What is “warming vs priming” inboxes?

Warming and priming are related but distinct concepts in cold email preparation.

Warming (sender-side):

• Builds your domain and IP reputation
• Focuses on sending infrastructure
• Establishes history with mailbox providers
• Measured by deliverability metrics and reputation scores
• Happens before and during initial campaigns

Priming (recipient-side):

Creates familiarity before cold email arrives

Touches prospects through other channels first (LinkedIn views, content engagement)

• Makes your name or company recognizable when email arrives
• Increases likelihood of opens and engagement
• Happens before specific outreach to specific prospects

How they work together:

• Warming ensures your message can be delivered
• Priming increases chances the delivered message gets positive response
• Both contribute to overall campaign success

Priming tactics:

• View LinkedIn profiles of upcoming prospects
• Engage with their content on social platforms
• Attend same events or webinars
• Get introduced by mutual connections
• One prepares the harbor, the other prepares the receiving party.
