Want to test whether one change to a post-purchase email helps customers place a second paid order?

This seven-page kit gives you a structured way to plan that test, check whether you have enough evidence to run it, and record what the result can actually support.

Inside the download:

Evidence worksheet: separate observations from hypotheses and decide whether to proceed, gather more evidence or stop.

Eligibility and randomization worksheet: define the customer group before assignment and preserve the split.

Three conditional email examples with editable placeholders and fact-check prompts.

Measurement definitions and a blank results log for distinct customers placing a second paid order.

Launch QA and stop checklist.

A clearly labeled fictional example, including an inconclusive result.

You receive the editable DOCX, a matching PDF, and a short readme with usage, license and support information. Both document formats are seven pages. The PDF is for reading/printing, not an interactive form.

Best fit: an online shop owner or small ecommerce team with authorized customer/order data, a spreadsheet, and the ability to keep test groups separate in its email platform. Some teams will need technical or analytical help. At low order volume, results may be inconclusive.

The worksheets are platform-neutral. The purchase includes no software, spreadsheet template, store integration, implementation, custom email writing or analysis service. The email examples must be adapted and all facts and links verified before sending. No increase in sales or other outcome is promised.

Requirements Microsoft Word is recommended for the editable DOCX; other editors may change its layout. A PDF reader is needed for the PDF. A spreadsheet or equivalent tool is needed to run the experiment and is not included.

License For one purchasing person or business and its team. You may fill in/adapt the worksheets and send adapted email examples to your own customers. You may not resell, sublicense, publish the kit, distribute blank templates to clients or other businesses, or claim the unmodified kit as your own. Keep attribution in copies of the kit; adapted customer-facing emails need no attribution. Separate client businesses need separate purchases unless written permission is given. Contra's Terms of Sale apply; mandatory legal rights are preserved.
