A client in Phoenix told me their email open rate doubled after they changed one word in the subject line
They switched from 'Your Monthly Report' to 'Here's your [Company Name] update for March'. Anyone else have a simple subject line tweak that actually worked?
Yeah, adding a date like Diana87 said seems to be the key. I read a marketing blog that said people are more likely to open something that feels current and specific, not just a template.
