10 Best Cold Email Software to Launch Successful Campaigns in 2021 (Full Review)

Companies spend thousands of dollars on email marketing and social media posting to increase their sales and keep existing customers coming back.

However, when it comes to the acquisition of new customers, cold emailing is still out there among the top best acquisition channels for both retail and tech companies.

An efficient cold emailing campaign can drive growth and have an amazing ROI.

So, What is Cold Emailing?

Cold emailing is an unsolicited email sent to a receiver without prior contact. Usually, companies use it to get in touch with people who could be potentially interested in their products or services.

Cold emails are not necessarily considered spam. Companies who are doing it right target specific audiences that are genuinely interested in what they have to offer. The key to cold emailing is to target the right audience and truly provide value with your email content.

When a company or an individual decides to bombard an audience with irrelevant and unwanted content, this practice is called spamming.

Essentially, cold emailing works as an advertisement that the receiver can opt-out from at any time so they don’t receive similar emails in the future. Cold emailing can be repetitive work as marketers will have to do endless copying and pasting. That’s where cold email software will come in handy.
