Every user’s need is different although they all are buying from one place. That’s why segmentation is a crucial part of email marketing. Otherwise, you’ll bombard subscriber’s inbox but they will not get benefitted from it. If you sell “t-shirts for nurse” why would you send emails to IT nerds? The targeted audience can get you better output. People normally don’t send an email to the spam folder if it’s relevant to them. If you can send emails on what they want, customers will love your emails even though they’re for marketing. The smart email marketing tools of today help you make the segmentation.
