This list with email addresses of B2B decision-makers who have shown interest can usher in considerable ROI. Here are the secrets to building a B2B email list:

  • Regularly clean your database

Prioritize cleaning up the database first. If you need a management strategy to keep the information gathered up to date, there is no point in expanding your email list.

Establish controls to regulate data input into your CRM and collaborate with an email list cleaning service or solution to routinely audit your database and maintain the accuracy of your email lists.

  • Showcase your subscription box

Only your website’s footer should not conceal your subscription box. Make signing up for your emails as simple as you can for visitors.

It would be best to mention your subscription box throughout the entire website’s content and place it front and center. The rationale behind this is straightforward: if readers of your blog posts, whitepapers, eBooks, etc. enjoy them, give them the option to read more by joining your email list.

  • On all web forms, provide an “opt-in” option

Give people the option to join your email list when they sign up for a free trial or submit a “contact us” form. Take advantage of the fact that this person has already shown some interest in your business!

  • Protect your most valuable content

Is any of your whitepaper or eBook doing exceptionally well? Put it behind a form and ask readers to join your email list for gaining access to this premium content. While we do not recommend gating all content, selecting specific pieces gives readers the impression that they are receiving an exclusive offer.

  • Give a discount

Giving your prospects and customers a discount for enrolling in your emails, or offering them discounts on special occasions, is another way to make them feel special. People appreciate a good deal, whether a dollar off or a free week of use of your product.

  • Pull it down

Although you can easily add new subscribers to your Customer Relation Management (CRM) using the internet, you can still get some of the best email addresses by going door-to-door. Always ask for business cards from people, whether you’re having lunch with a potential client, chit-chatting on the train, or running a large marketing event. Though it may seem dated, this method is effective.

  • Collaborate with a data provider

Even though organic email address collection is fantastic, working with a data provider is recommended. By analyzing your current database and creating email lists that reflect the traits of your best customers—people drawn to the information and communications offered by your company—leading data providers can help you increase sales.
