You can’t manage what you don’t measure. That’s according to an old business adage that’s still relevant in marketing today, especially now that marketers are drowning in an ocean of metrics and KPIs that let them know what works and what doesn’t. So what numbers should you be keeping track of to get a feel for how your B2B contact list is performing?
As you may know all too well already, everything in B2B marketing starts with your list. That’s why you need to keep this critical campaign component firing on all four cylinders. To find out whether your B2B contact leads database is really up to the task, here are the five key metrics you should always be monitoring:
- Inbox Placement Rates and Delivery Rates
Inbox placement rates (IPRs) and delivery rates are two distinct metrics that measure email deliverability, although they’re often incorrectly used interchangeably. Delivery rates count the number of emails sent that didn’t bounce, while IPRs only consider emails that actually made it into the recipients’ inbox.
These two numbers can indicate the overall health of your B2B contact list. Low IPRs and delivery rates are often taken as signs that a list probably needs some scrubbing and updating. Recent research from Return Path reports that average global inbox placement rates hover around 80%.
- Hard Bounces
Bounce rates refer to the percentage of total emails that were not delivered. Soft bounces happen when emails get rejected from the recipient’s server because of a full inbox. Hard bounces, on the other hand, take place when emails are not delivered because of invalid email addresses.
You want to keep an eye on hard bounce rates, since ISPs and mail providers view high levels of hard bounces as a sign of spammy behavior. To help minimize hard bounces, regularly scrub your B2B contact list for invalid or non-existent email addresses.
- Unengaged Subscribers
Unengaged subscribers are inactive contacts in your list that have yet to promptly opt out. These are subscribers who remain on your B2B contact leads database but haven’t opened or responded to your emails in a while.
Sending emails to unengaged subscribers can harm email deliverability, since doing this tends to trigger spam alerts in most ISPs. So, manage inactive subscribers with a reengagement campaign or by removing them from your B2B contact list altogether.
- List Churn Rate
List churn rate or attrition rate is the proportion of subscribers that either opt out or drop out of your list in a given period. Factors like the number of opt-outs, hard bounces, spam complaints, and subscriber inactivity are the main drivers behind list churn rates.
List churn tells you how fast your B2B contact leads database is shrinking. That’s why you need to acquire new contacts at a rate that exceeds the churn rate in order to grow your list. GetResponse estimates average annual list churn rates to be around 25%-30%.
- Spam Complaints/Reports
Every time a recipient marks your email as spam, you’re racking up spam complaints under your sender record. Once the number of spam complaints exceeds a given threshold, mailbox providers automatically classify your emails as junk. According to data from MailChimp, average spam complaint rates can vary from 0.01% to 0.04%, depending on the industry.
While spam complaints tend to reflect the quality of your email messages, they can also give you an idea about the quality of your B2B contact list. Email lists sometimes contain spam traps, which are email addresses created by mailbox providers to catch spammers red-handed. Clearly, it’s important that you find and remove this type of address from your B2B contacts leads database to help reduce the risk of incurring spam complaints.
Now, you know the crucial set of numbers that help you accurately gauge your contact list’s performance. To gain sharper insights on your B2B contact list, don’t just passively measure these metrics against industry benchmarks. Also actively run tests designed to optimize your database on a regular basis.
