To the Letter: Best Letter-Based Direct Mail Campaigns

It’s pretty obvious that we love direct mail around here. From finding the best ways to automate it to optimizing it, we care about everything that goes into creating a great piece of mail.

That’s why we started showing off our favorite pieces of mail over on our best direct mail campaigns page. The mailpieces in our collection have what it takes to catch consumers’ attention and drive action.

But there are a lot of different factors that go into creating a really great piece of mail: the form factor, the CTA, the copy, personalization and targeting, and so on. How do we know if our next direct mail campaign is the best it can be?

We thought it’d be fun to break down what’s working among some of the mailpieces in our best-of collection. This month, we’re taking a closer look at form factor and analyzing top-performing letters.

Creating a high-performing letter campaign

When we think of letters in direct mail, we often think of transactional letters or perhaps pre-approval letters for loans or lines of credit - but there are so many other creative ways to use letters in your marketing campaigns.

Let’s examine two brands that are effectively using letters in their marketing campaigns or using direct mail to streamline business operations.

Travelers - Auto insurance

This letter appears to have been triggered when a prospect looked at auto insurance rates with Travelers or used a calculator tool on the website. This acquisition campaign has many great elements working in its favor:

  • Simple design: This letter is easy to scan and has plenty of white space to bring balance to the letter. The use of red text also helps draw the prospect’s attention right to the Call-to-Action (CTA).
  • Action-oriented copy: Travelers is directly telling the prospect to choose them in their bulleted copy. It’s actionable and in the present tense.
  • Personalization: The letter includes the specific date the prospect looked at insurance quotes through Travelers, as well as their first name to tailor the letter to them.
  • Social proof: The use of a customer quote reaffirms the main message Travelers is getting across, that the prospect can save more than $600 by switching insurance companies.
  • CTA: The Call-to-Action is straightforward and provides two easy ways to take action, either calling a toll-free number or visiting a specific landing page.

Trafilea - Retail

The use of a letter by Trafilea (parent company of Shapermint) here is a great use case in testing different form factors as Trafilea does send postcards too. Using a letter helped them stand out among other promotional offers and provided a clear and sincere apology without worrying about space constraints. This retention campaign has some winning elements:

  • Copy: By using a letter format Trafilea had the space it needed to accurately explain what had happened, convey its regret over the shipping issues, and address how it plans to fix the issues. The letter feels more personal than a postcard with the same promo code offer.
  • Offer: The CTA is to give Trafilea another try and take $30 off with a custom coupon code.
  • Branding: The letter has subtle branding using its signature pink and a big “S” in the background that makes the letter identifiable to the customer but it doesn’t distract from the message.

To sum up, letters can be an excellent form factor for direct mail marketing for various campaigns. They can be personalized both to your brand and the recipient, and they’re actually the preferred form factor among many consumers. Our State of Direct Mail Consumer Insights report found that those 18-34 are significantly more likely to read letters and envelopes than those 35+.
