There are countless interesting statistics regarding HTML E-mail marketing, below is just a sampling of the statistical facts (from a McKinsey & Company report titled "Harnessing the Power of E-mail"):

• E-mail response rates average 15% vs. 1% for direct mail
• E-mail costs an average 3-10 cents each vs. an average $2 for direct mail
• E-mail generates 80% of responses within 48 hours

Remarkably, despite these facts, there seems to be reluctance among small businesses to embrace the systems that allow for legitimate, legal E-mail campaigns. Direct mail still has a place in marketing, but when facing the numbers why would anyone choose direct mail instead of HTML E-mail marketing? In many cases, an entire years worth of permission marketing can be paid for by foregoing just a single direct mail campaign.

The key to every business' success is the ability to attract, retain, and grow customers. Permission marketing allows businesses to communicate with prospective customers and current customers who are open to their message.

If your clients don't currently use permission marketing as part of their marketing strategy, consider a recommendation of adding it.
