How long should a cold email be?
Short — usually three to five sentences. Enough to show one relevant signal, its implication, and a single soft ask, and nothing more.
Should I personalize every cold email?
Personalize the reasoning, not just a merge field. One specific, relevant observation beats a name token and a generic pitch.
What's the biggest cold email mistake?
Asking for a meeting before giving the reader a reason to care. Earn the reply first.
Do subject lines matter?
Yes — keep them short, specific, and honest. A subject that overpromises hurts trust even if it wins the open.
