Why Do You Need List Building Services?
Here’s an eternal sales truth: You must concentrate your efforts on reaching the prospect before your competition does. Why? Because 82% of buyers accept meetings with sellers who reach out to them. Not only that, buyers want to meet sellers early in their purchase journey as well.
But sales reps spend only 28% of their week actually selling.
So, what takes up the other 72%? Tasks like prospect research and data entry. These non-selling activities can leech your sales team’s precious time and cost you your deals and, by extension, revenue.
This is where list building services can help you. By helping your sales team dive straight into selling the minute they log in, these services help your team do what they do best—prospecting and booking meetings.
Here are some more plus points of integrating these into your operations:
1. Save Time and Focus on Revenue-Generating Activities
By building a prospect list that’s ready to be leveraged, list building services put more time in your team’s schedule and allow your marketing and sales teams to concentrate on activities that directly affect your revenue numbers. No longer do your teams have to collate prospect lists to eventually start their activities.
Your sales and marketing team can hit the ground running. Sales teams can reach out to prospects confidently with cold calling, cold emailing, and build customer relations to drive repeat purchases, while marketing teams can launch email marketing campaigns, craft better conversion strategies, etc.
This allows your team to focus on bringing in the bucks rather than balancing their time between laying the foundation for selling and actually selling.
2. Access Reliable Contact Information
Reliable data is the foundation of your sales and marketing efforts. And so, the integrity of your prospect data pretty much decides the success of your outreach initiatives.
With B2B list building services, you get accurate and up-to-date prospect data. This helps you increase your email response rate, call pick-up rates, and email deliverability rate.
3. Target your Ideal Buyers Better
Another reason you should consider list building services is that these allow you to segment your prospect list into smaller groups to drive personalization and relevancy when targeting prospects.
For instance, you can divide prospects based on their current tech stack, and approach those prospects using your competitor’s tools with an emphasis on how your solution is better. Those prospects that have first-time buyers in your space could be pitched with a focus on how your offering can help them streamline activities.
This way, your sales and marketing efforts can be customized for prospects sharing similar characteristics, improving your chances of engaging fruitfully with them.
4. Get Better ROI
Custom list building services offer a vast database along with handy filters like revenue, location, technology, etc., to ensure your prospects match your ICP to the dot. This ensures you don’t waste time chasing prospects who have a low chance of conversion.
Thus, by pursuing prospects that are a good fit for your ICP, you improve your lead-to-sale conversion rate and, by extension, drive your revenue.
5. Contact Multiple Prospects in a Company
As a B2B marketer or sales rep, you don’t have to sell to a single prospect, but likely a buying committee. In such a case, you need to engage in account-based prospecting and contact each member of that committee.
But that’s easier said than done. Right from identifying who’s on the buying committee to researching them and gaining verified contact details, it's all on you. Well, not anymore.
A list building service leverages its extensive database to not only identify and research who to sell to in a prospect company but also bolster your efforts with verified contact details. Further, insight into their tech stack, firmographics, and company operations allows you to gain a comprehensive view of your prospect. All in a fraction of the time it would have otherwise taken your team to gain such information.
How To Choose List Building Services?
Now that we’ve discussed the leading list building services in the market and why you need to integrate one into your operations, let’s get into how you can identify the one that suits your team and goals best.
Here’s what you should look for:
- Data Source and Enrichment. Your chosen B2B list building service must collect data from multiple sources and have a robust data enrichment model in place. A traditional single source data list building service can cause a high email bounce rate as they have no way to verify their email addresses. Be sure to check your service’s number of data sources and enrichment model.
- Provides Both Email and Phone Data. Your chosen B2B list building service must be able to offer you both email and phone data on your prospects. A sole email list building service or phone list building service limits your sales prospecting efforts and hampers a multi-channel approach to outreach.
- Compliance with Privacy Regulations. Choose a list building service that complies with global data protection laws like SOC 2 Type II, GDPR, and the like. This helps ensure your prospecting efforts are based on legally procured data and helps foster customer trust while preventing legal action.
- Coverage of Contact Database. Next, evaluate list building services based on the extent of their data coverage. Your chosen service must have access to data across the globe encompassing APAC, NAM, and EMEA regions. Not only that, it must also offer depth in terms of job roles, industries and the like.
- Precise Targeting of Contacts. Go for a list building service that allows you to target prospects right to the T. For this, look for filters that can sift prospects based on technographics, firmographics, company revenue, employee, title, location, etc. This not only ensures you pursue prospects that fit your ICP but also helps gain targeted information within your database with a click of a button.
- CRM Integration. Your chosen B2B email list provider must offer seamless integration with your CRM system. After all, you can’t be expected to copy, paste, download, or upload data every time a fresh list gets generated or an existing database gets enriched.
It won’t just waste your team’s time but might even compromise the integrity of your prospect list if data points get missed or incorrectly added.
This might seem like a long list, but we assure you it’s what your sales and marketing team deserves. And to make things even easier, you don’t have to look far and wide for a list building service that meets all the above needs.
Prospect IQ by Klenty checks all the boxes above. Let’s see how:
