What thank you emails are
A thank you email is an automated message sent to express gratitude to a recipient for a specific action, such as a purchase, signup, or donation. These emails typically acknowledge the action and reinforce a positive relationship. They are a common part of customer lifecycle communication.

What 88 of them actually do
Thank you emails are often a neglected category, sent without much design effort. Most brands focus on warmth and direct communication. Two-thirds, 66%, are text heavy, and the same share use a monochrome palette, suggesting a functional approach. Despite the simple design, most brands send something warm, with 73% of thank you emails using a warm tone. I often wonder, "but can it write a heartwarming thank-you card?" This data shows many brands aim for that feeling.
Simplicity dominates the design and layout of these emails. Almost two-fifths, 39%, are plain text, and 58% use a single column layout. This suggests a focus on direct communication over elaborate visuals. Only 10% include a hero image, and product grids are almost non-existent at 2%. This indicates a clear preference for utility over complex design, with brands like Fair Fight and 24Slides often leaning into this minimalist style.
Brands often personalise thank you emails but vary widely in their calls to action. Two-thirds, 67%, address recipients by their first name, a strong signal of personalisation. The median email includes two calls to action. However, 30% include only a single CTA, indicating some brands prefer a focused message. I personally use a Claude bot to send short thank you notes to new Nitrosend sign-ups, which includes a single CTA to reach out with questions.
Thank you emails serve various stages of the customer journey, often with straightforward subject lines. They are spread across retention (26%), fulfilment (25%), and advocacy (23%), showing their versatility. Subject lines are typically direct, with 44% being transactional plain and 26% personalised. The Claude (Anthropic) welcome email, an RGE 2025 Award Winner in the Welcome Email category, successfully translates a sophisticated AI brand into a warm, approachable email, proving that even complex brands can master this simple form.
None of this helps if the send never lands, which is a promotional email problem rather than a design one.
