You can get really clever with your email subject line to increase open rates, but if the body copy and topic is inconsistent (or makes the subject line feel misleading), your clickthrough rate and long-term reputation will suffer.
Treating every lead as if they’re ready to buy might help you squeeze some additional sales out of the current month or quarter, but that will be at the expense of helping those customers buy down the road. Push them too hard now and they might not trust you later.
