Just realized my email subject lines were basically invisible
I had been writing vague subject lines like 'quick question' for months until a client told me she almost deleted my email because it looked like spam. Switched to putting the dollar amount of the deal in the subject line first and my open rate jumped 40% in a week - anyone else found a specific trigger word that works?
Man I used to roll my eyes at all the subject line optimization stuff, figured it was just marketing hype. But then I sent an email to a potential partner with the subject "partnership opportunity" and it sat unread for two weeks. Changed it to "quick 15 minute call?" and he replied in an hour. That really flipped a switch for me. Numbers work great too, I started putting specific dates in my subject lines like "meeting on March 5?" and people actually open them now. Your dollar amount trick is smart, I might have to steal that one.
