We live in an age of overflowing inboxes, where people have a fine-tuned ability to figure out what’s spam and do away with it without even clicking to open the message. This is why it’s vital that businesses craft tailored, relevant messages when carrying out cold email campaigns.
Personalization is the new golden ticket to a high clickthrough rate. If you want to stand out, your message needs to be customized. Unfortunately, when working at a high volume of contacts, doing this manually is impossible.
