At LinkBuilder.io, all of our work has a focus on cold email outreach. Sending emails to people you don't know truly is an art, and one which we'll investigate in more detail here.
We all know that personalized emails are great for outreach, and that we shouldn't be sending "one size fits all" emails to a lot of people simultaneously. However, not all businesses can afford to personalize every single email they send, especially when they send hundreds of emails every day.
This is why the conversation about cold emails is still open. But don’t get me wrong. I’m not talking about “hey-please-link-to-me-because-I-love-your-blog” emails. Cold emails that get responses require much more than that.
In this constantly updated post, we’re collecting all resources we find amazing when it comes to cold emails. And we hope you will find inspiration and useful tips here too.
