- messages must be designed for optimal usability with a user interface that works in the context of a crowded inbox and the user's typically hectic approach to reading mail
- therefore, the first two points to consider are the from field and the right subject line
- from field should clearly show two things: a recognisable brand name and a function that clearly distinguishes the message as a transaction rather than an advert, e.g. ship-confirm@amazon or membership-confirm@nimhe.org.uk
- in tests the main differentiator concerning successful subject lines was the degree to which the subject line explicitely related to a customer-initiated transaction, e.g. "Order has shipped" or Confirm your details for KC membership
- a webword study found that the shorter the subject line the more likely it was successful (ie gets read); so mabybe Confirm Your Details would be a better subject line
- body text
- no extraneous detail or fluff; start with information that matters most to users in the context of the transaction
- always include links to relevant pages of site if appropriate
- include information about what to do when things go wrong
