Most people now spend 10 seconds or less reading an email. If it doesn’t resonate with them, it gets ignored like the “Terms & Conditions” pop-up. 

An average email user receives around 121 emails daily, and it’s hard to stand out in the inbox. The only way out is personalization, as it catches attention faster than generic (read, boring) emails.
However, manual personalization is not scalable for your business if you run cold email campaigns and race out to hundreds of prospects daily. 

That’s where email personalization tools come in. This blog reviews the ten best email personalization tools to elevate your outreach game in 2025.
