Ask the Experts: If you could only use two email metrics, which two would you use?



For 2021, Webbula launched a video series where we sit down with email industry experts to discuss various topics within the email marketing world. 

Each month, Webbula introduces a new lineup of email experts with a new topic. Thank you to every email expert who participated in this video series and provided advice to other email marketers. 


1) Read Rate: Read rate is the most underrated metric in email.

2) Click-to-open rate: CTOR tells you more than just opens and clicks. It goes deeper into email engagement.

1) Engagement score: The engagement score is similar to a lead score. As a marketer, you can control what you want in terms of engagement. 

2) Link level reporting: Link level reporting allows you to track links in the email by categorizing them.

1) ROI (Return on Investment): You need to be able to understand what your ROI is on what you're doing.

2) Click-Through Rate: The open is nice, but if people aren't clicking on your emails and aren't engaging, what is the point?

Revenue: There is only one metric at the end of the day. KPIs are narcissistic. For me, being in sales, it's all about the revenue.

1) Clicks: Opens are now useless. Clicks are still an indicator that people are doing something. 

2) Inbox placement: Inbox placement helps you understand your email program and the health of your list.

Conversion Metrics: What your objectives are, is what your key metrics will be. It will be different based on the sector, B2B or B2C. Focus on conversion metrics rather than the easy-to-access metrics such as opens and clicks. For eCommerce, focus on conversion rate and customer lifetime value.

We often see marketers try to use metrics in ways they weren't intended. Or they see insights in metrics that don't exist.

1) Return on investment: Knowing if a project or email program is generating a positive ROI is very important for business justification.

2) Subscriber lifetime value: We are not in the business of managing campaigns. We are in the business of managing subscribers.

Focus on action is important.

1) Click-Rate: It's a strong indicator someone is engaging with your content. 

2) Conversion Rates: You want conversion. You want to drive the sale or lead form.
