TL;DR

How can I grow my B2B email marketing list organically?

Core Definition: Growing a B2B email marketing list organically is the process of attracting and converting interested prospects into subscribers through value-driven strategies, rather than purchasing lists. This involves using a solid CRM foundation, creating high-quality content, leveraging existing networks, and offering exclusive information to build a loyal and engaged audience over time.

Email marketing has re-emerged as a fantastic way to keep customers engaged and drive business growth. But its success hinges on one crucial element: a quality email list. Building this list from the ground up, organically and sustainably, is the foundation of any effective email marketing strategy.

  • Establish a solid foundation by consolidating all business contacts into a scalable Customer Relationship Management (CRM) system.
  • Create and promote exceptional content, such as blog posts and industry news, across all your channels to attract your target audience.
  • Develop gated content like eBooks or whitepapers that offer deep insights, requiring an email sign-up for access.
  • Incentivize subscriptions by offering exclusive content, special offers, or early access to information only available to your email list.

Email marketing has changed quite a lot in recent years. Its reputation has also cycled from a legitimate means for companies to stay in touch with their customers in the early days through a period of being seen as spammy, if not a bit scammy, and back to a fantastic way to keep customers engaged.

Start On The Right Foot: The CRM

Establish a solid foundation for your email marketing by implementing a scalable CRM and migrating your existing contacts. Drive sustainable subscriber growth through exclusive content, gated assets, and strategic website opt-in forms.

Effort: 1-2 weeks Tools Needed: 2
1
Select and Implement a CRM Solution

Centralize your leads and subscribers by choosing a scalable Customer Relationship Management platform. Ensure it supports essential marketing tools, social media integration, and email automation.

2
Import and Engage Existing Contacts

Enter your current business cards and phone contacts into the newly selected CRM. Send an initial outreach email asking them to legally opt-in to your newsletter and forward it to their network.

3
Produce and Promote Valuable Content

Publish informative blog posts containing industry news and in-depth product insights. Promote these assets across social media channels with clear calls-to-action that encourage email subscriptions.

4
Design Exclusive Email Content

Dedicate a section of your content calendar exclusively to your email newsletter. Keep subscribers engaged with custom articles, polls, and contests rather than merely rehashing old blog posts.

5
Gate High-Value Marketing Assets

Identify popular blog topics and expand them into comprehensive eBooks or whitepapers. Require visitors to provide their email contact information in exchange for accessing these premium resources.

6
Deploy Website Pop-Ups and Slide-Ins

Remind website visitors to subscribe using non-intrusive pop-up or slide-in forms. Configure these prompts to appear after a thoughtful delay and ensure they are easy to dismiss.

7
Highlight Subscriber Exclusivity and Offers

Emphasize that your newsletter provides exclusive deals and deep-dive data completely unavailable on the main website. Embed sign-up forms on every webpage, social update, and email signature to maximize visibility.

Leverage Existing Contacts

Remember those phone contacts and business cards? Get them all entered into your newly selected CRM and do some outreach. Email your existing business contacts with a legal basis for communication (e.g., a prospect showing interest), asking if they'd like to subscribe to your new email newsletter, and include an opt-in link. That will mark them as subscribed in your CRM, so they'll get your messages.

Then send a follow-up asking those same people (the ones who opted-in) to forward your first newsletter to anyone they think would benefit from hearing from you. Good contacts have other good contacts, so take advantage of your existing network to build your marketing list.

Craft Awesome Content

If you want people to subscribe willingly, the ultimate goal here is to offer them something they value. The best way to do that is with a solid content marketing strategy built around regularly publishing engaging, informative blog posts. Offer industry news, in-depth looks at how your product impacts your sector, personal interest stories about your team and how their work shapes your company’s future, and anything else you know your target audience will be interested in.

Then, promote that content across channels. Tweet out links to each story you publish (can be done via marketing automation), post to Facebook with additional updates along with links, and don’t forget to let your LinkedIn connections know when a piece goes live. And, of course, don’t forget the call to action in each of those updates. These CTAs are crucial for getting people to click through and subscribe for future updates.

Create Engaging Email Content

Once you generate and promote exceptional content, consider what you will send to your growing contact list. You don't want to bore them with rehashed posts from the blog, or they'll unsubscribe just as quickly as they signed up in the first place. You also don't want to be off-putting and send nothing but pushy sales pitches. Instead, create a section of your content calendar specifically for your email newsletter.

Write custom articles that are only available to subscribers. Conduct polls asking for feedback on recent updates or create contests where the prize is some branded swag or free product.

Gate The Good Stuff

Once your list grows and people read your content via social media, email links, etc., it's time to create gated content. Technically, gated content is only available in exchange for something from the viewer. For content marketing purposes, this usually means asking for email contact information in exchange for access to an eBook, whitepaper, or other special content not available more widely.

Don't just pick a blog post to the gate, however. You've got to make it something special to justify your audience giving up contact info for it. So do a deep dive into a particular topic that's been popular on the blog, or maybe write a whitepaper on the state of a certain industry segment if you're a thought leader. Anything that goes deeper into a subject you know your audience is interested in is a good candidate for gated content.

Use Pop-Ups And Slide-Ins

This one requires some finesse to do right. What you don’t want to do is send readers running away from your site when they’re hit with pop-up after pop-up or a slide-in form so tenacious they can’t get rid of it.

You want to remind visitors that you have an email newsletter that offers more value than a quick visit to the site can provide and a simple form where they can get signed up. Don’t forget an easy way to close the message should they not be interested or already a subscriber, and remember only to set these messages to appear after a pause and not to return too frequently.

Remember That Exclusivity Sells

We touched on this earlier, but it’s important enough to warrant its section. Your email must offer something beyond what a person can get by browsing your website. Special offers exclusively for subscribers or deeper dives into subjects that matter to them. Then you promote that these deals and information are only available to those who subscribe, making the form easy to find. 

The fact is that exclusivity sells. People like feeling special, and having access to sales and data that nobody else has access to accomplishes this quite well. The key to these suggestions is including sign-up forms on every site page, links from social media updates, and at the bottom of every email you send. That way, an interested party won't have to dig to get on the list.
