Cold email campaigns remain a staple in email marketing because they get real results. For lead generation, finding potential customers, networking, and even making direct sales, cold emails cut through the noise.
If your emails aren't landing in the primary inbox, sometimes it's the fault of the content you're sending. Other times, underlying issues prevent you from sending emails to certain servers. This is where MxToolbox comes in, helping you look up the MX record, IP address, and other data to find out if sending emails to a domain is possible.
Cold email outreach can be a powerful way to start business conversations - if you do it right. But in 2025, with evolving data regulations and inbox filters getting smarter, many sales teams and founders ask the same question: Is cold emailing still legal?
Your call to action might be the missing link if your cold emails aren't getting replies and conversions. A good CTA turns interest into action, and a vague one stops momentum cold.

For a while, the Cold Email Mastery course was one of the most talked-about resources in the cold outreach space. Freelancers, agency owners, and B2B marketers used it to learn the basics of cold email marketing and land their first clients.
Your email might be perfectly crafted. But if it lands in the spam folder, it’s game over. The line between cold email and spam isn’t always obvious, but it is critical. Especially if you want to protect your email sender reputation and get replies.
