Ask Do personalized subject lines actually make a real difference in open rates?

[Meridian]

Personalized subject lines have become common in email marketing, and many businesses swear by them. Adding a person's name or mentioning something related to their interests can make an email feel less like a mass message. This small touch often grabs attention faster than a plain generic subject line would. Still, personalization only works well when it feels natural and not forced or repeated too often. How much difference do you think personalization really makes in getting an email opened?
