40+ Best social proof email subject lines

Social proof is like seeing a crowded restaurant and thinking, "This place must be good if so many people are eating here." It's all about people looking to others for guidance and reassurance when making decisions, especially when unsure. So, in simple terms, it's the idea that if lots of folks are doing or liking something, it's worth checking out!

Social proof emails can be a real game-changer for getting more people to open your emails and get engaged with what you're sharing. They work like a friendly nudge, helping to show your subscribers just how awesome your products are and why they should be excited about them!

That's why we've gathered captivating subject lines to kickstart your social proof email campaign:

Best social proof email subject lines with reviews

Testimonials are a game-changer in the customer journey! People trust products with reviews from real customers more than those without. Why? Because we're all a bit skeptical of what companies say – we know they want to sell us stuff.
