While cold emailing is a great way to get your name and brand in front of prospective clients, sending cold emails from your primary domain may not always be the best approach. It is important to use an alternate domain for cold email outreach for a number of reasons.
Using an alternate domain for cold email outreach will protect your primary domain's reputation. When you send emails from your primary domain, the spam filters of email service providers can detect unsolicited emails. If your emails are marked as spam, it can harm the reputation of your primary domain, which can have a negative impact on your email deliverability in the future. Using an alternative domain will ensure that your non-sales related, 'business-as-usual' emails do not land up in the spam box.
An alternate domain can help you segment your email list and keep track of your marketing efforts. When you use an alternate domain for cold email outreach, you can create a separate email list for your cold outreach campaigns. This way, unrelated outgoing emails will not have an impact on your open and click rates, keeping your results as accurate as possible.
Using an alternative domain is an affordable way to give your campaign the best possible chance at success. Domains can be purchased for as little as $12 from providers such as GoDaddy.com, Domain.com, Namecheap.com and many others.
