|Vanguard Security Update email|
The email opens in an emphatic tone. It speaks like a communication from Vanguard; that is, the tone fits their their brand identity of taking a stand for investors and treating them fairly.
The second paragraph contains the call to action. It cites a shared responsibility. It explains what is being requested and why.
The third paragraph includes a time-specific call to action. The response window is four weeks -- a bit long in internet time, but fair considering the actions involved.
The fourth paragraph explains (in plain English) what the reader needs to do. Although the call to action is to do something after logging into the Vanguard web site, there is no hyperlink to the login. We may reflexively consider this an error, but it is actually an email security best practice that guards against phishing attacks.
Finally, there is a polite close reinforcing the cooperative nature of the call to action.
There are a couple potential minor improvement opportunities. I would consider adding a valediction, along the lines of "Sincerely, Vanguard Customer Service" or perhaps a couple FAQs. But these are based on my intuition and outside understanding of the target market. In the best possible world, if timing allows, an A/B test could be executed to see which edits would result in improved response.
- When communicating with customers, your communications style should be aligned with your brand.
- Requests to your customers should be date specific.
- A/B test every communication as feasible.
