7 Tested Techniques to Sell More Direct Mail Services

In partnership with Impactable.com


Identify which mail marketers anonymously visit your website

Who’s Mailing What! integrates with the Impactable.com Account Data Platform to inform you when a mailer visits your site, allowing you to see the campaigns being sent by that site visitor. Via the Impactable Account Data Platform, the direct mail marketer decision makers are captured to power your awareness building and lead generation campaigns. These are “high intent” prospects since they have already checked out your website. Then build relationships with these hot prospects via the next technique…


Build awareness with an account based multi-channel marketing campaign

The fastest growing direct mail service providers don’t try to get every potential customer. They invest the time to narrow down their audience to the very best “Ideal Customer Profile”. Then, they relentlessly reach out with messages across numerous channels. Our integration with Impactable.com allows you to instantly send messages via LinkedIn connection requests, LinkedIn ads, digital display ads, email and even Facebook with a single click for each prospect.

Create persuasive new business pitches that blow away your competition

The most credible presentations are packed with facts...what is your prospect’s competition sending out? What formats are they using? What discounts or specials are they offering? With Who’s Mailing What! you have 150,000 direct mail examples at your fingertips, all in downloadable PDF documents.


Help your clients get better results from their campaigns

One idea: Offer an integrated multi-channel campaign. This strategy has proven over and over to boost results. For example, VeraData serves the non-profit fundraising industry with audience solutions. They have shown that donations increase by up to 18% if the mail campaign audience is “warmed up” with a Facebook campaign. Another resource, Direct Mail 2.0, partners with printers and agencies to manage cross channel campaigns. They see lifts in response rates up to 44%!


Attract and nurture your best prospects online via authoritative content

Are you ranking high on Google and Bing? Take a look at your toughest competitors with a tool like Semrush. If you’re not beating your competition when people search for information, you’re leaving money on the table. But creating authoritative original content is not easy. Fortunately Who’s Mailing What! can help. Who’s Mailing What! offers packages of co-branded, informative and search engine optimized original material for your blog. Our track record in the direct mail industry speaks for itself if you look up our traffic statistics. Let us do the same for you. Then, once you are attracting solid qualified traffic, identify and market to those prospects via Technique #1 above.


What is your niche market strategy?

Our friends at Impactable.com recommend reading “The 7 Figure Agency Roadmap” even if you are not an agency. In the advertising services space, specialists win. Offering something unique is helpful. What vertical do you have the most experience in? Who’s Mailing What! enables you to research and demonstrate expertise in more than a dozen industries. You can be an instant expert in what offers are being sent right now and which formats are working the best.


Focus on inexperienced marketers and hit them fast!

Look for marketers with successful businesses that are spending money on other channels. Find those who are early in their journey of experimenting with direct mail. Reach out to them before they get results from their current campaign. Who’s Mailing What! is updated daily with new campaigns. If you use data from Who’s Mailing What! to educate these “newbies” on improvement opportunities you have a high likelihood of displacing their current vendor (assuming that vendor made some clear missteps with the campaign).
