    Cold Email Marketing

    Cold emails can be useful when providing decision makers with an opportunity to get acquainted with your offer and start a business relationship.

    Expert Email Marketing Campaign Strategy for B2B businesses help to monitor key metrics.

    Here are the primary cold email KPIs that every business should track.

    Open Rate 

    The open rate is the metric of recipients opening your email. If you have a high open rate, it means your mail is noticeable.

    Also, using an email validator helps to clean your list to avoid sending non-existent addresses. But if you have a low open rate, it indicates your subject line requires improvement. The subject line should be short and personalized. 

    Click-Through Rate (CTR)

    The CTR is the number of recipients who click on the link you send in the email.

    CTR is relevant because it indicates the level of interest people have toward your content and if it makes them move to another level. Perhaps the video or ad’s CTR is low because the content does not interest the group, or the next step to take is not clear.

    Conversion Rate

    The conversion rate indicates how many of the recipients acted as required by going through your email and clicking on the URL link to fill in a form, sign up for a service, or buy a product. Measuring conversion rates explains whether your emails contribute real value to your company. To enhance the conversion rates, please ensure that your emails have a great, strong, and heavily focused call to action button, and such a button should lead to another relevant and optimized landing page.

    Bounce Rate

    Bounce rate measures the number of emails that could not be delivered to a specific recipient’s inbox. High bounce rate is not good for your sender reputation and, in this way, can affect your email delivery. There are two types of bounces: hard bounces –faults of a permanent nature, such as an invalid Email address, and soft bounces –Temporary problems, like a full email inbox. It is good to cleanse your email list, so you have a minimal bounce rate and thus a good sender reputation.

    Reply Rate 

    Reply rate is the number of people who reply to your email. It is crucial to know how many actually showed interest. 

    To enhance this measure, one should design emails, including appealing for response invitations, where questions tend to be open-ended.

    Unsubscribe Rate

    The unsubscribe rate shows the number of recipients who no longer want to communicate with your company. A high unsubscribe rate can be a result of many factors. Some could be:

    • Receiving too many emails
    • Getting irrelevant information
    • Unvaluable content

    This way, you can detect problems with your email frequency, or the quality and relevance of the content you’re sending out. The rate that you should aim towards achieving is a low churn rate; to achieve this, one should ensure that the content is relevant to the interests of the target group.

    Forward Rate

    Forward rate is the number of times that your received message is forwarded to other recipients, which boosts your contacts’ circulation and thus brand recognition. Availability of a high forward rate has implications that make your content interesting enough to be passed around to other people, bringing new leads and prospective customers. To promote this kind of forwarding, provide substance that will look useful, revealing, or a deal that will compel people to forward it to their friends.

    Lead Quality

    Lead quality evaluates the business prospects of the leads produced by your emails. A high quantity of leads does not equate to quality; tracking lead quality makes sure that the contacts that you have generated are interested as well as are suitable for your product or service. To identify which leads are of higher quality based on attributes such as company seniority, industry, and activity level, all leads should be ranked through lead scoring.

True revenue recognition is based on a CRM or an analytical system in which conversions from cold email to final sale can be traced.
